So my mother and step-father bought a pontoon this summer and with that dreaded W word coming I mentioned to him about winterizing. It is a 40HP 2 stroke Merc. No water systems onboard to deal with so just the engine and fuel system. I told him to dump some Star-Tron in the tank and run it a little while to get it up into the fuel lines. Also mentioned using fogger but not sure how on an outboard and have never even done that on mine. Anything else need done to make sure all water is drained from the engine?
