    • Add fuel treatment and stabilizer to fuel tank(s) as required per gallon • Change water separating fuel filter, if equipped. • Connect portable fuel tank containing manufactures recommended winterizing fuel, stabilizer & oil mix. • Run engine up to operating temperature, circulating winterization mix to protect internal engine parts. • Reconnect engine fuel line. • Drain and refill lower unit gear lube and install new washers. • Pressure test lower unit if any indication of water exist • Change engine oil and filter using only quality products. • Grease engine fittings.

    That is good advice from bubbakat, and I want to add, do not spray fogging oil into the intake of any EFI engine. The oil will put a coating on the MAP and any other sensor in your intake, causing problems with the engine management system next spring.
