Boat engines are different than other engines. They may operate on gas and need oil but special care must be given to ensure they are winterized properly.
* First, Start off by consulting the owner’s manual. This will have detailed instructions on what must be done to secure your motor for winter.
* Visible nicks and scratches should be painted to prevent corrosion and you should also change the engine oil and filter.
*Engines must be flushed with fresh water prior to storage. Be careful when performing this procedure because all water must be drained prior to winter storage because even a small amount of water can freeze and cause damage to the engine.
*Check inboard or stern-drive engine antifreeze is filled to prevent freezing. It may be advisable to replace this with new antifreeze each season as a precaution.
*Add fuel stabilizer to any remaining gas in the tank and run the engine for a few minutes allowing the treated gas to circulate. This will help prevent the clogging of jets and injectors.
*spray fogging oil it into the carburetors while the engine is running. Turn off the fuel supply and wait for the engine to stop. This will burn off any fuel left in the system.
*Remove the plugs and spray some fogging oil in the cylinders and rotate the engine manually a few times to ensure the oil penetrates through the cylinder.
*Replace the spark plugs and open the carburetor drain. This will remove the last bit of fuel that may be present in the system.
*Remove the prop and inspect it for damage and debris. Lubricate any moving parts as per the owner’s manual and replace the prop.
