I have a 1992 Crownline 183br. The transom seems to be a 3 piece design. The center where the out drive mounts is about 3 inches thick, while the sides are only about 3/4 inch thick. I have a soft spot on one of the sides above the floor and was wondering what I could to to repair it. This part of the transom is not exposed to the outside water as it is under the cap and encapsuled by a swim platform.
