How To Maintain a Marine Vessel’s Engine

Posted on

A properly running engine ensures your marine vessel takes you where you need to go. Few things are as panic-inducing as when the engine fails while at sea. Stuck in the middle of the ocean or bay water without a properly running engine is not something most of us want to deal with. Proper engine maintenance can help you prevent that from happening and help you prepare in case it does happen regardless of where you are.


Boat engines filter water to keep them cool as they operate. Without a properly running strainer, the engine can become clogged with grass, sticks and other debris floating on the surface of the water. A clogged engine can fail to run. Check the raw-water intake filter prior to departure. Order the Groco strainer replacement part before you need it, so you have it on hand for a quick, easy replacement.


The boat’s engine uses oil and other fluids to operate various parts. Unlike a car, the engine oil of a boat needs replacement annually or after 100 hours whichever comes first. Replacing your engine oil isn’t a task you have to go to the dealer for, but you can. Some old rags, an oil wrench and a pair of gloves can make the job less messy and easy to finish.


Fuel is essential to operating your boat’s engine. Before launch, make sure you have enough gas in the tank to get you where you want and back with some extra to spare. You never know what may crop up while out on the water. Check the fuel lines annually to make sure there are no worn spots or cracks.


As part of your regular trip maintenance, it is a good idea to flush the motor. Fixing a clog before you leave is much easier than on the water. Debris stuck in the motor prevents it from properly running. Regular maintenance of the engine lets you enjoy many hours of boating.
