Thanks for the comments everyone. I've opened a can of worms with this project. I knew purchasing the boat that it would need the floors replaced, but once you remove a section, you'd have to remove another section that was damaged underneath. At the moment, it has been gutted completely and the transom has been replaced. The foam insulation was partially soaked and had to be removed. I've since float tested the boat to check for leaking rivets and have cleaned the floor to prep for a rubberized sealant. I'll post pictures as this project takes shape. Rollcaster............
