On the advice of the Chicago Sea Ray Service Manager, I went ahead and had them winterize the boat before going into heated storage. What he said, which made complete sense to me, is you winterize not just to prevent freezing but also to provide corrosion protection to those systems that use water. The engines are fresh water cooled so the blocks already have antifreeze with corrosion inhibitors. The reason I chose heated storage was to reduce thermal changes on the boat and prevent excess moisture over the winter.
My basic question for the future is two fold. First, is the corrosion protection that critical over the winter? Second, if the first is true, am I really wasting money on heated storage and would be just as well off with unheated covered storage?
