So I think that I am going to winterize my boat myslef. My plan was to not do it all because to boat is in a heated garage but I would feel better and not have to worry if I did it. This procedure is great but it doesn't talk about the heater. My boat has one and I was wondering if anybody had any input on how to winterize that too. Obviously pictures would be great but if nobody has any handy then just instructions would be awesome. Thanks for any input.
