I have a 1985 Gator Bass Boat. The previous owner had a hole for a seat in the floor that went all the way down to the foam. We just bought the boat a couple of weeks ago. Everything is ok with the 50 hp evinrude thats on it, and the prop is right. We're thinking that maybe the foam got saturated with water because the boat will not go over 10 mph. Could it be THAT saturated that it would weigh the boat down that much? IF SO, is there any way to dry out the foam?
