I'm putting in a new wood transom on the back of my aluminum bass boat. The transom sits in between two thin walls of aluminum. The three layers are held together with 2 1/4 inch screws and nylon lock nuts, and also with the motor mount bolts. I want to seal the ends of the screws (where the head and lock nuts tighten up to the aluminum) and need advice on what sealant to use. Several of the screw holes are below the waterline. Any recommendations?
