I would like to rebuild my front motor mount (inline 6). What is the best way to remove the old one and prepare the fiberglass in the hull? I assume I will make the new one out of 2x8's or whatever it takes to get the correct height. Bevel the ends to fit the shape of the bottom, notch out a drain and coat with resin before installation. Do I glue the boards to the hull? if so, what glue? or just set them and cover in mat and resin? or both?
