• Marine Engine Maintenance Guide

When you’re  yachting ,  fishing , or running commercial boating , you need to know how to maintain your marine engine. A clean and cared for diesel engine keeps every passenger on your boat safe, so it is critical that you conduct proper boat maintenance.

From how to take care of your engine cooling system to basic marine diesel engine maintenance, you want to understand everything involved in owning and taking care of a marine engine. First, you may want to know the typical costs of boat service, repair, and maintenance.

How Much Does Boat and Marine Engine Maintenance Cost?

A variety of factors affect the cost of boat and marine  engine maintenance and repairs . What you pay to maintain your engine and boat depends on the following:

• The type of boat and engine
• Who performs the repair
• The type of maintenance or repair
• Whether or not your engine needs a diagnosis
• The part of the engine that needs repairing or maintenance

Your location may also have an impact on the marine engine repair cost, but in general, the problem with the engine is the most significant factor along with who repairs it.

If you want to know how much boat maintenance costs if you hire an expert to do the work, contact them beforehand to get an estimate. It’s a good idea to interview several repair companies, to get an idea of the typical price of the work you want to be performed. While you do want a good deal, you don’t want to choose the cheapest option.

Your boat needs maintenance and repair. Working with an inexperienced company or trying to do the job yourself can mean it needs more extensive repairs, at a higher cost, down the line.

Know what you need to maintain gives you an understanding of how much you can expect to pay.

Most Common Marine Engine Problems

Some types of marine engine problems are more common than others. If you notice any issues with your boat or engine, it may be one a lot of boat owners experience. Some of  the most common marine engine problems  are:

• Blown fuses
• Corroded electrical connections
• Loose alternators
• Loose belts
• Clogged fuel filters
• Clogged sea strainers
• Old antifreeze
• Water or other materials in the fuel
• Damaged impellers
• Plugged mufflers

While some of these are an easy fix, you may have something more complicated on your hands. Depending on the problem or combination of problems, you could need new parts or help from an expert, including  an engine rebuild . Some repairs and maintenance are simple to conduct on your own, though.

Follow the Manual

Sometimes, the answer to questions like “Do I need to change my boat oil every year?” or, “How do I clean my marine engine?” are easy to find. The boat’s manual might give you step-by-step instructions or otherwise guide you through the process of changing the boat’s oil or cleaning the engine.

You don’t want to rely on general directions or advice when it comes to making repairs to your specific boat model. The maintenance and repair processes are often different for different models and engines. When in doubt, read the manual.

Some of the information you’re likely to find in the manual includes:

• Changing the oil filter:  Your manual should tell you what type of oil filter to use in your marine diesel engine. If you use the wrong one, you risk restricting oil flow throughout the engine.
• Putting the raw-water pump back in:  Your manual may advise you to take your impeller out in the fall and replace it in the spring, which is an essential part of engine maintenance. You’ll also want to check your manual when putting the pump in place again. You should find a tightening sequence and torque specs for hose clamps. Follow the steps when reinstalling your raw-water pump to avoid issues with the mechanism.
• Re-torquing cylinder heads:  You should leave the process of re-torquing cylinder heads to the pros. Your manual should tell you how often you should have someone perform this maintenance. The frequency is based on hours of operation for your engine, so be sure to keep track of how much use the boat gets.

Consider your manual your ultimate guide to boat maintenance. If you have any questions, read the manual, as you’ll likely find a helpful answer there.

Whenever you perform any maintenance tasks, be sure to keep records. Taking notes on repair and maintenance is good practice for any mechanical system, especially marine diesel engines. It lets you see when a task was performed and can help you determine what an issue might be.

A few things to document when it comes to repairs include:

• A description of the issues
• What you did to correct the issue
• Who performed the maintenance or repair.

Keep the maintenance log somewhere safe and remember to update it whenever you conduct anything from basic marine diesel engine maintenance to complex repairs. You can take notes on engine hours of operation and create a calendar or schedule for repair in another section of the log. Recording how much use your marine engine has gotten will help you know when it’s time to re-torque cylinder heads or change the oil.

Your maintenance and repair notes will be useful to anyone who uses your commercial boat or performs repairs. If a driver notices an issue with the engine, they can consult the notes to see if it’s an ongoing problem. A repair person can review your notes to see if similar problems have happened before or if past maintenance work could have contributed to the current issue.

When You Need a Professional

While prior knowledge and a manual will help with certain fixes and upkeep, some systems require  the help of a professional . When it comes to engine maintenance, rely on someone with experience and the right tools to take care of:

• Valve adjustments:  Any diesel engine needs a periodic valve adjustment to keep everything running smoothly. Making a mistake when adjusting the valve of a marine engine can be disastrous, which is why it’s best to leave this one to the pros.
• Re-torquing cylinder heads:  After a certain number of hours of operation, you should have a professional re-torque the cylinder heads. A professional knows the specifications to follow during this process. The specs need to be followed precisely to avoid harming the engine.
• Turbochargers:  Turbochargers help an engine’s power and efficiency, so you don’t want to risk any damage to them. They also need specific service specs, which are best left to the pros.
• Engine control module (ECM) and common-rail engines:  An expert will use their computer to inspect electronically controlled engines further. You can conduct basic service, but be sure to take it to an expert for more in-depth repairs.

If you ever feel unsure about what to do, your safest option is to connect with someone who knows what they’re doing. You don’t want to risk damage to any part of your boat, especially when you use it for commercial purposes.

How Often to Change Your Boat’s Oil

One maintenance task that’s easy enough for most people to handle on their own is changing the oil in a boat engine. Oil does a lot for a marine engine, such as:

• Lubricating the system and reducing friction
• Keeping the pistons and cylinders cool
• Sealing cylinder walls, turbochargers, and valve stems
• Keeping out contaminants
• Preventing corrosion

How often you need to change the oil depends partly on how frequently you use your boat. Usually, you’ll want to change the oil after a certain number of hours of use or in the fall, before you put the boat away for the winter. When you change the oil, also replace the filter, gaskets, and seals at the same time.

Check your oil before every trip to make sure there’s enough in the tank. You don’t want to risk running low.

Know Your Cooling System

The  cooling system is one of the four critical aspects  of a marine diesel engine — along with fuel, lubrication, and electricity. A malfunctioning cooling system can damage the entire engine.

A cooling system has two main components:

• The raw-water system:  The raw-water system takes in seawater for the rest of the engine system. The seawater cools your engine’s freshwater and exhaust gas before leaving the system. It enters through an in-line pump and exits through the exhaust system.
• The freshwater system:  The freshwater system services the turbocharger, cylinder jacket, and cycle head. Since the freshwater system is a closed-loop, it relies on raw-water to cool it.

The raw-water and freshwater systems contain other components that keep them functioning, just as the engine as a whole does. Clogged sea strainers are not just one of the most common marine engine problems, but they are  the number one cause of failed boat engines . Along with that issue comes raw-water impeller failure.

A properly functioning impeller should look like a gear with rubbery veins. Over time, the part absorbs seawater. As a result, the impeller and its veins harden, bend, or break. If that happens, your engine can’t pump seawater in to cool down freshwater and other systems.

Removing the impeller in the fall keeps its veins from hardening. You can reinstall it in the spring or get a new one to replace it. You’ll need a socket wrench and a tool to remove the impeller, but they are worthwhile purchases since this is a maintenance task that you need to do yearly.

When caring for your freshwater system, focus on the pressure cap. Without a proper seal, your engine could overheat, so choose a quality seal and install it according to specifications. Another simple maintenance fix is changing antifreeze every two years. Use extended-life varieties and only mix with distilled water to keep your marine engine running right.

Some maintenance jobs should be performed by a professional. For example, every three years, you must remove the heat exchanger for cleaning. You should send this device to a professional, but with most engines, you can remove it yourself. Remember, though, that if you have an ECM or common-rail engine, an expert should take care of the entire process.

Maintain Your Fuel

What’s the simplest way to take care of a diesel engine? Keep your fuel tank full. A full tank helps prevent microbial growth in the tank, which can harm the engine system. Other things to do to take care of your fuel system:

• Maintaining the fuel filter:  Before every trip, be sure to check the inspection bowl. Drain it and rerun it if you see any water. You’ll have to replace your fuel if the bowl fills with water the second time you inspect it. The boat’s manual should let you know what type of fuel filter to use if you need to replace the one in your engine.
• Bleeding the fuel system:  Air in the fuel system spells disaster for a boat’s engine. Since it will shut down the engine, you need to know how to bleed the fuel system to remove air. There should be a hand pump, which you can access after loosening the screw on the filter. Pump until only fuel comes out of the system. You’ll have to vent the fuel-injection piping with a fuel line wrench if that process does not work.
• Cleaning up spills:  Spilled fuel could be hazardous to others or damaging to your boat. After refueling or maintaining your marine engine’s fuel system, check for any spills. Use dish detergent to help break down and clean up the diesel. While a spill doesn’t impact your fuel system, it can affect your boat.

The ultimate boat maintenance checklist to make sure your yacht is ready for launch and the start of the sailing season

Check your rudder for hairline cracks or damage

Boat maintenance: Mast & Rigging

Check all your standing rigging connections. Credit: Colin Work

• The mast cap is out of sight, out of mind 99% of the time, but serves multiple functions: backstay, forestay, cap shrouds, radio antenna, nav lights, halyard sheaves. Rotate mast and boom sheaves to check they are not misaligned or worn by a bad halyard lead. Lubricate sheaves with WD40 or silicone grease.
• Spreaders, gooseneck, mast heel, kicker, mainsheet and topping lift connections all need checking for wear, damage or corrosion.
• Check for galvanic corrosion between different metals.
• Check electrical connections, deck and spreader lights.
• Wax mast tracks and luff grooves with candle wax or Teflon spray.
• Standing rigging: Look for areas of wear or stranding on the wire. Check mast tangs, T-ball joints and rigging screws.
• Wash furling drum and swivel and check they move freely. It’s common for the top swivels to become stiff and sometimes seize, which can compromise the forestay wire.
• Running rigging: check for chafe and that the shackles aren’t seized. Sheets, halyards, warps: wash in fresh water to get rid of salt and grime.
• Deck winches : strip down, wash parts in paraffin, wash off with soapy water and lightly regrease .
• Windlass : if manual, check it’s working, clean and tighten. For powered versions check foot switch for water, clean and use Vaseline on the connections.
• Anchor chain : Re-mark lengths if faded, or add chain markers. Check for condition and wear.

Head, bilge & gas

Check bilge pumps it might sound ok but is it actually attached to a hose?

• Check impeller on bilge pumps and grease with water pump grease only (Vaseline will rot impellers)
• If you have an automatic bilge pump, check float switches work.
• Dry bilges thoroughly then if water appears after relaunch you’ll know you’ve got a leak.
• Fill water tank and add purifier such as Puriclean or Milton
• If the pump on the heads is stiff look to service and lubricate with silicon grease.
• If you have a gas sensor, check it works.

Boat maintenance: Below waterline

Hull and skin fittings.

Check jubilee clips for rust. Credit: Bob Aylott

• Most vessels have DZR (dezincification-resistant brass) seacocks. Look for any signs of corrosion on the skin and tail joints, which are common points of failure.
• Ensure all valves are greased.
• All hoses should be double-clipped. Check jubilee clips for rust . Do you have wooden plugs attached in case of emergency?
• Check skin fittings are free of blockages/ growth or antifouling.
• Check anodes have plenty of life . Don’t forget prop shaft and saildrive anodes.
• Check leading, trailing and lower sections for damage or hairline cracks.
• Check for play in bearings, stock or quadrant. Movement should be minimal. Grease steering cable.
• Check for stress cracks or movement internally and externally – especially at the keel root and around the internal framing or matrix, and around fastenings and backing washers.

Prop shaft & stern gland

• To check bearings, grasp prop in both hands and try moving it up and down and from side to side. There should be little, if any, movement – no more than 2mm.
• Check P-bracket for stress cracking from misalignment or damage.
• Stern gland packing. Many yachts have some form of deep-seal arrangement that has a service life of around seven years. Those that have a proper stuffing gland will need to be greased to prevent drying out and getting brittle. The gland may need pulling down or repacking at some point.
• If you have a saildrive, check the condition of the seal and the metal ring that holds it in position. Again, note the seals have a life expectancy of between five and seven years depending on manufacture.

Boat maintenance: Mechanics

Check all filters

• If you didn’t change the oil when you laid up, change it now.
• Change fuel filters.
• Remove rags stuffed in outlet pipes from winterisation.
• Impellers – if removed at lay-up – reinstall with a smear of water pump grease.
• Reinstall the engine belts and check tension: there should be no more than half an inch of play.
• Check oil levels. Check durability of the gaiter seal. Check rubber faring and reseal if necessary.
• Change internal engine anode.
• Check engine mount is secure.
• Check diesel tank for water from condensation . Drain off or replace fuel. Add an appropriate biocide to help kill off diesel bug .
• Check inaccessible wiring, such as bonding wires from the anode and earthing wires from the starter motor. Clean the terminals and smear them with Vaseline or silicone gel.

Batteries and electrical systems

• Check electrolyte level if yours is an open lead acid battery; tighten battery securing straps and make sure vent for gases is clear. Clean terminals and coat with Vaseline. For sealed batteries, check the condition of indicator light, or other charge indicator.
• Switch on instruments and use backlighting to help reduce any condensation.
• If the anode looks serviceable for another season, check bonding and wires. If they haven’t worn at all they may not be working so check Ohm resistance max 0.2 from propeller to anode.
• Check for chafe, wayward stitching and tears. Do you carry a sail repair kit?
• Take to a sailmaker if the sacrificial strips is worn out.

Make sure your navigation apps are up to date

• Update charts from Notice to Mariners .
• For electronic charts, check with your supplier how to update. New chartplotters can connect to WiFi, or you may need to connect the chart chip to your PC at home and download the update.
• Download operating software updates for your chartplotter and instruments.
• Make sure your subscriptions for navigation apps on phone and tablets are up to date with the latest charts.
• Check age of hoses. If they are over five years old, they should be replaced. Check for kinking or wear in gas hosepipes. If in doubt, replace.
• Check hose clips are tight. Hoses behind cookers should be armoured.
• Check thermal cut outs on hob, grill and oven work.

Harness/lifelines

• Check stitching and get repairs done by a sailmaker if necessary.
• Jackstay and Danbuoy lines: check condition and points of security.
• If you have the traditional type, check the bulb, battery and that it actually works. The new types have various ways of testing, and all have an expiry date.

Lifejackets

Is your lifejacket fit for purpose and in good condition? Credit: Theo Stocker

• Inflate using mouth tube. Leave inflated overnight to check for leaks .
• Wash with fresh water
• Weigh cylinder and check lights if fitted.

Stanchions/lifelines

• Check stanchions and make sure lifelines are still suitably secured at each end and cords and pins are in good order.
• Watch out for wire failing if you have plastic sheathing.
• Make sure these are in date, in a watertight container and are easy to reach. It’s worth having gloves and goggles to hand too.
• Make sure these are in date and registered with the correct contact details.
• Ensure this and the hydrostastic release are within the service date, and you are aware of its contents .
• If its secured with a rope, consider if you could release it in an emergency with ease.
• Make a grab bag up with essentials

Boat Motor Maintenance & Engine Care

Follow these basic steps to maintain your boat's engine:

• Read your owner's manual.
• Avoid fuel problems.
• Avoid battery problems.
• Complete annual servicing, either DIY or by a professional technician.
• Winterize your engine (if used in a colder climate).
• Check your propshaft.
• Boat Maintenance Guide

Read Your Owner’s Manual

The marine engine owner’s manual outlines basic maintenance procedures and has a schedule for regular maintenance. If your owner’s manual is missing a dealer can order you a new copy, or you may be able to order a paper copy or download a digital copy from the engine manufacturer’s website.

Avoid These Two Common Problems

When a marine engine has a problem, it’s usually related to either fuel or the battery.

Avoid Fuel Problems

• When possible fuel your boat with gasoline that does not contain ethanol. If only ethanol-blend fuel is available, make sure to only use fuel with up to 10 percent ethanol (E10). No marine engine is certified to operate on fuel with more than 10 percent ethanol. Try to by fresh gas from a busy fuel dock or gas station.
• Use a fuel stabilizer additive if you don’t anticipate using most of the fuel in your boat within a week or two. Modern gasoline can begin to oxidize and form trouble-causing deposits in the fuel system in just a few weeks, especially in older engines fitted with a carburetor rather than fuel injection.
• Install a 10-micron water-separating fuel filter between the fuel tank and the engine, which will have a spin-off filter element. Many newer boats are already equipped with these filters, which can keep water and very fine particles of debris out of the engine. Carry a spare filter element on the boat.

Avoid Battery Problems

• Always replace the engine cranking battery with another marine battery, which has thicker plates and a more-robust design than an auto battery to withstand the vibration and pounding a boat can deliver.
• Secure the marine battery with a good battery tray, which should have a base that is screwed or bolted to the boat and either a rigid bracket or a locking strap to hold it to the base. You don’t want the battery banging around in rough water.
• Frequently check the battery terminal connections to make sure they are snug and free of corrosion.
• If you use the boat infrequently, use a maintenance-type battery charger to keep the battery fully charged between outings.

Annual Service

Follow the service schedule outlined in your marine engine owner’s manual. Most outboard, sterndrive and gasoline inboard engines require basic service every 100 hours or annually. This basic service will include an oil-and-filter change (for four-stroke engines), changing the gearcase lubricant in outboard and sterndrive engines, changing the fuel filter element, and perhaps installing fresh spark plugs. A good service shop will also check the accessory belt on sterndrive and inboard engines, inspect and replace sacrificial anodes as required, and check the condition of power steering and hydraulic trim fluid. Make sure the water pump impeller is changed on schedule. This service is often combined with winterizing the engine for off-season storage.

Winterizing the Engine

This procedure will also be outlined in the owner’s manual. If you will be storing the boat in a climate with below-freezing temperatures a sterndrive or inboard engine will need to have its cooling system flushed with antifreeze. This expels all of the fresh water from the cooling system, which could otherwise freeze and damage the engine. Even engines with a closed cooling system that is filled with antifreeze may need to be flushed to expel water from the exhaust and heat exchanger. You can do this yourself but it’s really a task best left to a marine service shop. Many shops will combine winterizing with annual service.

Learn More in our Winterization Guide

Diesel Issues

Keep the tank full and use a quality diesel additive to prevent microbial growth. Check the fuel filter inspection bowl for water before every trip.

Clogged sea strainers are the most-frequent cause of engine failure on inboard diesel engines (and inboard gasoline engines). A fouled strainer prevents raw water from being drawn into the cooling system. Check yours before each outing.

Check Your Propshaft

Outboard and sterndrive owners should remove the propeller(s) several times a year to check the prop shaft for fishing line. Line discarded in the water can become wrapped around the shaft and will eventually damage the prop shaft seal, allowing water to enter the gearcase, which can lead to catastrophic failure and an expensive repair bill. Again, check your owner’s manual for instructions on removing the prop and inspecting the shaft.

Boat And Trailer Maintenance Checklist

Advertisement

Take care of the boat, trailer, and engine and the chances of a problem occurring on the water or the road will be minimized. Here's what you need to know.

Whether you do it yourself or leave it to the pros, routine maintenance is essential to keep your rig in tip-top shape.

So you're a new boat owner. Your pristine center-console sits proudly in your driveway, the outboard shining brightly in the sun, and even the trailer is sleek and polished. How can you keep it at least close to looking and performing as it does now? Maintenance is the key.

But if you're not mechanically inclined, how can you properly care for your new rig? If you're all thumbs, budget in some bucks for dealer maintenance. In this case, it's probably best for both you and your boat if you leave the mechanical details to the pros. You can, however, perform all the tasks that don't require technical expertise. Such tasks as keeping fittings and moving parts lubricated, cleaning and waxing the finish, checking the drive lubricant and engine oil, making sure that fishing line isn't wrapped around the prop shaft — these are all examples of simple skills a responsible boater should learn, especially to protect his or her investment. While boats have never been cheap, they seem to be more expensive than ever when compared to the average paycheck, so it's smart ownership to make sure that all is up to snuff.

To help you out, we've created a simple Timeline and Maintenance Chart, one that works for DIYers and tech-savvy boaters alike. Refer to the chart to check maintenance items before every outing and at every 20, 50, and 100 hours of use. Seasonal boaters should consult the chart before every layup. With our chart as your guide, your rig will stay like new for longer and command top price at resale or trade-in time, particularly if you keep records of what you've done and when. The chart is the suggested schedule, although some boats may require more frequent checks. If in doubt always follow the manufacturer's recommendations for your particular boat, engine, and trailer.

A Guide to Yacht Engine Maintenance

• by yachtman
• September 4, 2023 August 26, 2023

Yacht engine upkeep is a must for any yacht owner or captain. There are several maintenance tasks to keep in mind, such as checking oil levels, replacing filters, inspecting belts and hoses, and keeping it clean and lubricated. Don’t forget fuel management either! Impure fuel can lead to serious engine damage.

Now, here’s a cautionary tale. Once upon a time, a passionate yacht owner neglected his engine’s maintenance. He overlooked routine check-ups and ignored minor issues. On an adventurous voyage with friends, the yacht suddenly stopped working in the middle of the ocean. The owner was overcome with regret for not taking better care of his beloved boat. Until help came, they were stranded.

Importance of Yacht Engine Maintenance

It’s vital to regularly maintain a yacht’s engine for its optimal performance and longevity. Not doing so can have terrible effects, such as costly repairs or even complete breakdowns while sailing.

Doing the maintenance involves various steps. These steps include:

• Changing the oil
• Inspecting & cleaning the fuel filters
• Checking wear & tear on belts & hoses
• Making sure there’s proper ventilation

By doing these regularly, yacht owners can prevent problems from becoming major ones.

Owning a yacht symbolizes luxury; keeping it in better condition requires proper maintenance. The engine is the heart of any vessel; without it, a yacht is just a floating piece of art. Therefore, taking care of the engine and ensuring it's running smoothly is essential. Here are some yacht engine maintenance tips to help you keep your luxury vessel in top condition.

Schedule regular maintenance and inspections .

Regular inspections are one of the most important things to do when maintaining a yacht engine. Inspect the engine and its components every time before setting sail. One crucial aspect of yacht engine maintenance is conducting a comprehensive examination of critical elements like the engine, fuel system, cooling system, and more to detect and address any possible concerns before they escalate into significant complications. For example, look for signs of corrosion, loose wires, or oil leaks. A quick inspection can save you from bigger problems in the future.

Check and Change the oil regularly .

Checking the oil level in your yacht's engine is crucial for proper maintenance. Your engine oil should be changed regularly to ensure maximum performance and longevity. Ensuring the engine has its oil changed regularly is crucial for maintaining its lifespan. The oil lubricates the engine's moving parts, reducing friction and preventing wear and tear. Change the oil every 100-200 hours of engine use or as the manufacturer recommends. Use high-quality marine-grade oil that's suitable for your engine.

Keep the fuel system clean .

Contaminated fuel can cause serious damage to the engine, including decreased performance and reduced fuel efficiency. Therefore, it's important to keep the fuel tank and lines clean. Use a fuel stabilizer to prevent the growth of algae and bacteria. Also, change the fuel filter regularly to prevent debris from clogging the fuel system.

Fuel filters are a necessary part of your yacht's engine system. They prevent impurities, dirt, and water from entering the engine and causing damage. Fuel filters should be checked and replaced regularly to ensure they function correctly.

Turn off the engine and close the fuel valve to replace the fuel filters. Locate the fuel filter housing, usually on the engine or fuel line. Remove the filter housing cover and remove the old filter element. Replace the filter element with a new one that matches the specifications recommended by the manufacturer. Tighten the housing cover, open the fuel valve, and start the engine.

Monitor engine temperature and oil pressure .

Regular monitoring of engine temperature and oil pressure is essential to ensure the health of your yacht's engine. Overheating can damage the engine and other components, so monitoring the temperature gauge and taking action if it starts to climb too high is important. Similarly, low oil pressure can lead to engine damage, so it's important to monitor the oil pressure gauge and top up the oil as needed.

Maintain the cooling system .

The cooling system of a yacht engine is crucial in preventing overheating. Check the coolant level regularly and replace it if necessary. Inspect the hoses and clamps for any signs of wear and tear. Also, clean the sea filter and the heat exchanger to prevent clogging.

Check the belts and pulleys .

The belts and pulleys of the engine need to be checked regularly. Examine for indications of damage, such as cracks, fraying, or wear and tear. Tighten the belts if necessary, and replace them if they're damaged. A loose belt can cause the engine to overheat, leading to costly repairs.

A dead battery can ruin your day out on the water. Therefore, it's important to inspect the battery regularly. Inspect the connectors for any indications of rust or oxidation and clean them thoroughly if needed. Also, check the voltage and replace the battery if it does not charge.

Keep the engine room clean .

A clean engine room is essential for the proper functioning of the engine. Dirt, dust, and debris can clog the air filter and cause the engine to overheat. Therefore, it's important to keep the engine room clean and well-ventilated.

Store your yacht properly .

Proper storage is also important for maintaining your yacht's engine. If you store your yacht for an extended period, drain the fuel system and fog the engine to prevent corrosion and other damage. It's also a good idea to cover the yacht to protect it from the elements and prevent damage to the engine and other components.

Lastly, it's important to seek professional help for yacht engine maintenance. While regular yacht engine maintenance is essential, it's also crucial to schedule professional maintenance and inspections periodically.

Quick & Easy Boat Engine Maintenance Checklist...

Quick & easy boat engine maintenance checklist.

Ever get the feeling that you haven’t done everything you can to make sure your boat is in tip-top shape? Then there’s a chance you don’t have an adequate boat engine maintenance checklist. The good news is that a maintenance checklist doesn’t have to be so cumbersome that it ruins the experience of owning a boat altogether. Here’s a quick and easy guide to caring for your engine that can help you keep your engine performing its best.

Essential Items For Boat Engine Maintenance

When it’s time to maintain your boat engine, here are the items you won’t want to miss:

• Cleanliness. Is your boat clean? Is the engine itself in good shape when you give it the “eyeball test”? Browse BoatLIFE’s cleaning products to identify the best product for your engine.
• Oil. Think of oil as the lifeblood of your engine. Just like a car, your boat needs its oil changed to function properly. Many boat owners recommend changing the oil for every 100 hours of engine use—which tends to mean about once per year, depending on your individual consumption. You can either learn how to change your specific engine’s oil or take it in to a dealer for an oil change.
• Propeller inspection. How does your propeller look? You can use a deep well socket to remove a propeller on an outboard boat motor and ensure that seaweed or fishing line hasn’t gotten through, which could severely impact the quality and function of your motor. You’ll also want to inspect for signs of damage, because dings and dents can have a surprising effect on the efficiency of your motor. There’s no sense paying all that money for gasoline if your propeller isn’t giving you full efficiency.
• Regular flushing. DiscoverBoating.com recommends flushing out the engine after every trip—freshwater or seawater. This involves starting up the engine to let the water pump works its magic—and don’t forget to inspect the pump itself. After it’s finished, they recommend disconnecting the fuel line to burn the rest of the fuel left in the carburetor.
• Inspection. Continually inspect your engine for leaks and damage. Discovering a leak may not be a fun prospect, but it’s better to address it quickly with a boating professional. Inspect your engine after every use. For long-term maintenance, regularly inspect the fuel line for cracks, as well as the fuel primer bulb and any relevant fittings. You’ll also want to check for common problems including rust, corrosion, fuel tank damage, water in the fuel, and the proper functioning of the tank vent.

Final Thoughts

Sound like a lot? Once you get your boat engine maintenance checklist down pat, it will seem like any other routine. Just make sure to take good care of your engine and bring it in to a professional when you’re in doubt. And don’t forget to stock up on BoatLIFE’s maintenance products to ensure you always have a clean engine that’s in good working condition.

• Before every outing, check all lifejackets on board to confirm they are still in good working condition, including life jackets for children . These may not be a part of your boat, but it is your legal responsibility to wear one while on board, making them an essential element of boating safety equipment.
• Regularly check any elements of the boat that could be implicated in a rescue , such as navigation lights , visual distress signals (including flags) and radios to confirm they are in good working order. 
• Check all other safety equipment , including boat fire extinguishers and backfire flame arrestors , ladders and ropes, and throwable PFDs to confirm they are not expired and in good condition.

Checklist: Seasonal boat maintenance

• Beginning of the boating season : Change the oil, inspect the fuel system, and check the electrical system. Clean and maintain bilge pumps, inspect safety equipment, and clean and wax the boat. Ensure your registration and boat insurance are up to date.
• At the end of the boating season: Winterize mechanical systems by draining water and adding antifreeze. Remove and store canvas and loose equipment, and clean and wax the boat. Change oil and filters, fill fuel tanks, and use stabilizing agents to prepare the boat for storage.

Boat maintenance costs

Annual maintenance costs are typically around 10% of the boat’s original price, though this can vary based on size and usage. Regular maintenance efforts are well worth it, as they can extend your boat’s lifespan and prevent unexpected issues.

Whether your sailboat is stationary for a long time, or whether you live and travel with it, there are several key things to keep an eye on. Regular maintenance of your sailboat will ensure more years of use and better performance. Furthermore, your sailboat will be safer and it will keep its value longer. Below you’ll find a checklist for routine mission-critical checks. Some of these checks have to be performed both daily and monthly. Others require monthly and annual checks, but always make sure to inspect everything, thoroughly. Follow the steps of the list and ensure trouble-free sailing.

The engine of your sailboat is something that requires a lot of care and attention. Inspect regularly the condition of the engine and look for corrosion, as well as make sure that the outboard motor is securely in place. Daily maintenance of the engine consists of:

• Check the engine’s oil level.
• Check the belt tension.
• Transmission fluid level.
• Inspect pulleys as well as the alignment.
• Alternator and water pump belts have to be tight.

And now we’re moving on to the monthly maintenance of the engine which includes:

• Change the oil and filter of the engine.
• Clean the thru-hull.
• Clean the siphon break.
• Fill up coolant and antifreeze if needed.
• Check pump, impeller, and raw water strainer.

Finally, let’s see the annual maintenance of your sailboat’s engine:

• Test the batteries.
• Check the diesel tank for damages.
• Inspect the shaft and propeller.
• Change primary and secondary fuel filters.
• Bleed the fuel system.

Check the Bilge and Bilge Pump

The bilge is situated at the bottom part of the sailboat and collects excess water. The bilge pump is the piece that removes water from the bilge. If the bilge pump is damaged, your sailboat can even be sunk! In order to keep yourself and your boat safe, check the pump hoses for debris that could cause clogs. In case you find a leak, the first thing you should do is to taste the water. Is it freshwater or saltwater? So, every few days survey the bilge for oil, water, or fuel leaks. Moreover, it’s important to lift a central floorboard often just to ensure that the bilge is dry. Leaks can be caused by different areas. For instance, leaks that come from holes in the deck, loose hatch seals, or improperly sealed windows.

Always inspect probable damages to your sailboat, even if it’s in a well-maintained condition. It’s recommended to make monthly and yearly checks to make sure it stays in perfect condition. Firstly, inspect the hull, keel, and rudder and look for any damages, cracks, and blisters. Then, make sure that the drain plugs are in place. Apply gel coat restorer or a rust inhibitor to the scratches or to the rusting of your sailboat’s bodywork. Moreover, you will also need to remove your sailboat from the water, once a year. It’s easier to do this during the winter months and although this can be a costly thing to do, is really worth it. Like this, you’ll get a better image of the hull’s condition and fix anything that needs repair. Finally, remember to annually carry out anti-fouling and any re-painting or zinc replacement.

Raw Water Strainers and Freshwater Levels

Don’t forget to check your seas strainers! If you’re running your generator, heat/air conditioning, or anything that requires saltwater or raw cooling system to function, you might want to surveil your strainers. Furthermore, inspect the water flow on all of the raw water cooling systems. You have to see an easy flow of heating, Genset, refrigeration, and aircon cooling water out of the system. If the freshwater system, which is pressurized by an accumulator tank gets too low, then it throws the whole system out and thus it will not be working properly. So, it’s imperative that you never let your water tanks empty.

As for the electrical system it is recommended to check it every month. Check the condition of the wires, if they’re neatly secured, dry, and inspect their casings to see if they are intact. However, there are some sailboats that have their generator running periodically to charge them up. So, keep an eye on your battery’s charge levels. Also, the electrical lines must be in good condition to keep the electrical system on your sailboat up and running. Any damaged lines could provoke a fire hazard. To prevent electrical lines from erosion, remember to keep them clean, and use a digital multimeter to make sure everything’s working properly.

Without the battery, which is the heart of your sailboat, the engine won’t start, nor the electrical components will work. So, take good care of the battery and check it once a year, or more often, i.e. during the boating season. Keep in mind that batteries naturally degrade over time, so this is a must task to perform. You can check the battery’s charge with a digital multimeter, and the connections for corrosion. Moreover, test the batteries and check if they’re clean and dry. There are sailboats that have solar and wind power that continuously tops up the batteries. Other sailboats depend on having the generator running periodically in order to charge them up.

In case you’re running the generator you will need to check its vitals at least once a week. So, check the oil, belt, water level, and inspect for leaks and loose connections. You can see the leaks easier if you keep the Genset clean.

Oil and Filter

Remember to regularly change the oil and oil filter. In case you don’t, then it is possible to provoke damage to the engine parts. In order to change the oil, let the engine run for about seven minutes, then turn it off. Subsequently, place a container under the drain plug. Take out the drain plug and loosen the screw that is located above. Then, let the oil drain out for about 30 minutes. During this process change also the oil filter. After the oil drains out, replace the drain plug and tighten the screw. Finally, fill the engine with the proper oil.

Fridge and Freezer Temperature

The effectiveness of a fridge often depends on the temperature of the sea. Many boat refrigeration systems get a charge over time which makes them less effective. Therefore they slowly reduce the temperature gauge. So, it is recommended to change the temperature gauge at least once a week. The temperature of the fridge has to be below 5 degrees and the freezer below freezing.

Sails and Rigging

Sails and rigging have to be checked at least once a month. Firstly, look out for any chaffing where the headsail sheets attach to the clew, and also to the traveller and boom vang. Secondly, examine thoroughly if there’s any wear on the mainsail. Then, check if the cotter pins and shroud are in place and in good condition. Finally, make sure that the turnbuckles and pelican hooks on the lifeline are in good condition.

Summary- Maintenance List

Your sailboat’s maintenance needs to be taken seriously. When you’re regularly maintaining your sailboat, you also ensure its life spanning. Some basic items that require constant maintenance are the generator, the battery, the plumbing, the bilge, oil, and the fridge and fluid levels, among others. However, there are others that require monthly or yearly maintenance, such as the engine, the electrical system, the sails and rigging, the propeller, zippers, hinges, upholstery, etc. In case you can’t repair or check the condition of these parts, then consider contacting a professional to help you with the maintenance process.
