dont know...keep it in a garage--unheated though and we did have a cold winter so you might be right.
Have big time problem now.....noticed when i was on the lake yesterday boat took on a bunch of water. pulled all of my batteries out and noticed a bunch of corrosion under the batteries and have some water or battery acid dripping out under the boat in the garage now. turning the concrete floor white. #@!@##!!!!
going to take a spray bottle with baking soda/water mix and spray the heck out of everything and let it soak down the bottom of the boat to the leak and then try to seal with aluminum sealer. wonder if that will eat through my plastic gas tank?

might be in over my head on this one......any help appreciated.
