Boat Engine Maintenance:

How To Keep Your Engine Running Smoothly


One of the most important things you can do for your boat engine is to change the oil regularly. Check the oil level in your engine every time you take the boat out for the day. If it's low, add more oil. Also, keep an eye on oil quality. Using a high quality engine oil offered on you can be sure that you are giving your engine the best protection against the harsh marine environment. If the appearance of the oil turns milky in color, this could indicate that you have water intrusion into your engine and should be addressed immediately. Be sure to check your owner's manual to find out what type of oil is best for your engine.

Gear Lube.

Another important aspect of boat engine maintenance is changing the gear lube. Your lower unit has several gears that rely on quality gear lubes to minimize friction and overheating. Over time, lower units can become susceptible to leaks and allow water to enter, and mix with the gear lube. This will greatly reduce the gear lube's ability to maintain proper lubrication and protect your gears from damage. Regular inspection can help you identify leaks early and reduce repair costs. This should be done according to the manufacturer's recommendations.


Boat batteries are essential for starting your engine and powering accessories. Most marine batteries are lead-acid batteries and require special care. Check the battery regularly for corrosion on the terminals, which can be cleaned with a mixture of water and baking soda. If the battery is more than three years old, it's probably time to replace it.

Keep your engine happy.

By following these tips, you can help keep your boat engine in good working order. Regular maintenance will prolong the life of your engine and help ensure that it runs smoothly when you need it.
