I have a 1984 Cheetah 142 bass boat and was wondering if there is foam on the floor that can get water logged? The floor is awful close to the hull of the boat being it's s tri hull. I ask because I installed a depth finder a couple of days ago and when I drilled into the transom water trickled out. Could this be coming from the transom or is it water logged? I can move the boat around on the trailer by hand with no problems really so it's not real heavy but I'm concerned about the water in the boat. I do know the transom needs work but the floor is solid to me. What do y'all think? It's a 14' bass boat with s 25hp Mercury on it.
