Winterizing takes way too long. I do as little as possible to get the anguish over with as I am more excited in the spring to do more. It takes me a couple of hours but I drain the gas tank, run stabile gas through the carb, fog the engine, drain the system and remove the battery. I take off all the bling on the tower and lower it and cover the boat for a long winter's night. I leave it outside all year long so I also remove the trailer pads, the rear deck and the spare tire.
