The engine of your boat is a complex mechanism that needs a wide array of maintenance products to remain in good working condition. Some of them are meant to increase power and reduce fuel consumption, others are developed to ensure reliable protection and fewer breakdowns. Whatever your needs are, you should have a basic set of engine maintenance products in your dock box to treat the problem (or ideally, the symptom) as soon as it appears. This list might include a WD-40, anti-corrosion spray, engine degreaser, thread locker, lubricating oil, antifreeze, water absorber, gasket sealant, and other helpful products.

To prevent serious issues, it’s highly advisable to do some basic check-up after every outing. Flush the engine to see if the pump is working correctly and outflow tubes are not clogged, then burn off the fuel left in the motor and carburetor to avoid build-up. Finally, take off the cowling and make a visual inspection for any leaks or defects. These simple steps can help you keep your boat engine in top condition for a long time. And for more serious maintenance jobs, turn to our website and get everything needed for your boat to run without a hitch for years to come.
