Boat Maintenance Guide. Most outboard, sterndrive and gasoline inboard engines require basic service every 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.
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. Many shops will combine winterizing with annual service. Learn More in our Winterization Guide. 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. Shop Collection. Boat Building. Chrysler Outboard Repair Manuals.

Electric motors are lightweight and almost no noise, easier in construction and cheaper to operate. However, due to the fact that powerful electric motors would require too large batteries, they are produced at low power - up to 5 hp.
Electric motors are usually used in water bodies where the use of gasoline engines is prohibited for environmental reasons or where excess noise is undesirable.
The power range of the internal combustion engine is much wider, they are enough even for operation on the most high-speed and heavy vessels. The sailing range is much higher than on boats with an electric motor. Such vessels can go into plane mode, which reduces fuel consumption. However, these models weigh more electric. In addition, they are more expensive both by themselves and in operation.
