[QUOTE="JMichael, post: 299148, member: 7544"] When I started my mod, one of the first things I did was to remove the flooring. Below the carpet/aluminum was a layer of 1.5" foam. It was so badly water logged that there was no way it could ever dry out. So the hull was constantly exposed to having a layer of water trapped in there. Pitting was non existent on the hull floor. The transom wood was also saturated and that was keeping the inside of the transom constantly wet. The inside of the hull at the transom was pitted so badly that it had eaten all the way through in some areas. So just having water trapped against the aluminum is not the problem. I'm not sure why my transom corroded so badly when the floor didn't but they were both exposed to prolonged periods of water being trapped so there is some other factor causing the problem. I don't have many details about my boats history but as far as I know this was all based on exposure to fresh water. [/QUOTE]
