Changing the oil and filter on a boat is most likely the boat maintenance chore that gets neglected the most. That’s inevitably because it’s a dirty job that seems too complicated, especially if you’re not mechanically inclined! So, you procrastinate and make excuses until your engine performance tanks – or fails altogether. Here, we’ll give you an all-in-one DIY guide on how to change your boat oil, what to expect, with a few pro tips along the way.
How Often Should You Change Boat Oil?
Ideally, you should change your boat’s oil and filter every 100 hours of runtime or every season. But one thing to note is that every engine is different, so it’s always best boating practice to refer to your owner’s manual.
Let’s face it: in the midst of the glorious summer days out on Lake Travis, the last thing you’ll want to do is deal with changing your oil. It’s easy to rack up long hours out on the water with those glorious lake days.
A safe bet to ensure you’re consistently maintaining your boat, regardless of the hours put in during the summer season, is to always have it serviced before storing it for the winter. This way, you can ensure that your boat is properly maintained for the following summer season.
If you’re unsure whether it’s time for a boat oil change, watch for warning signs such as dark or gritty oil, reduced engine performance, unusual engine noises, or an unknown maintenance history. Staying ahead of routine oil changes is one of the simplest ways to protect your engine and avoid more expensive repairs later.
How to Change Boat Oil Step by Step
To change your boat’s oil, you’ll need tools, oil, and a filter. You’ll want to pick up the manufacturer-recommended OEM oil filter and marine oil in accordance with your owner’s manual.
You will need an appropriately sized oil filter wrench, a box wrench for the crankcase drain plug, or one of two varieties of oil change pumps. You will also need: a large-capacity bucket, grease rags, and a sealable plastic baggie. Once you’ve gathered all the necessities, you can begin!
Warm Up the Engine
Now the real nitty-gritty fun begins. Ladies and gentlemen, start your engine! Allow it to warm up to at least 130 degrees and turn it off. The reason we do this is twofold. Hot oil drains more easily, bringing up gunk and contaminants that are unhealthy for your engine.
Drain the Old Oil
Next, place your bucket into position. Begin draining your oil by either pulling the drain plug or using your preferred oil drain pump. Once the flow has slowed to drips, replace the drain plug or close the oil pump’s valve. Be careful not to overtighten or cross-thread the plug!
Replace the Oil Filter
Grab your filter wrench and loosen the oil filter until it moves freely by hand. Grasp the filter with a plastic baggie and finish removing it without spilling. Place the filter upright in the bag, seal it, and set it aside.
Wipe the oil filter housing mount with a rag to ensure a clean surface and that there’s no double gasket causing a leak. Place a small amount of new oil on your index finger and smear it onto the gasket of the new filter. Finally, screw the new oil filter on snugly by hand. Again, do not cross-thread or overtighten.
Refill with Fresh Oil
Refill your crankcase with the recommended oil in the recommended amount. Never overfill or underfill, and be sure to clean up any spills or drips. Replace the oil cap and start the engine. Allow it to run for 60 seconds – watching for leaks around the plug and filter. If you spot a leak, immediately stop the engine and correct the problem. Otherwise, check the dipstick level. If it is still below the proper level, add small amounts of oil until it is full. Viola! You’re done. Easy peasy!
Dispose of Used Oil Properly
After you’ve successfully changed your oil and filter, give yourself a pat on the back, and then be sure to dispose of the used oil properly. It’s crucial never to pour used oil onto the ground, into storm drains, or into the lake. Collect the old oil and used filter in sealed containers and take them to a local recycling center or automotive parts store that accepts used motor oil for recycling. Proper disposal helps protect the crystalline waters of Lake Travis and keeps harmful contaminants out of local waterways.
Boat Oil Change Cost
The cost of a DIY oil change varies depending on your boat’s engine size and the required oil type. Changing the oil and filter yourself can cost anywhere from $50 to $75, depending on your vessel and any supplies you may need. If you choose to take your vessel to a service technician, you’re looking at spending around $300 or more, so it’s still cost-efficient to do the oil change yourself if you feel comfortable.
While routine oil changes are a small investment, staying on top of regular maintenance can help extend your engine’s lifespan and reduce the risk of more expensive repairs down the road.
