The guy who is doing my transom refused to just fill in the area where the notch was due to the fact that my bracket would bolt up between the notch and a new section. If the bracket would have bolted up on the factory transom he would have just fill it in. As it turned out he found my transom was in worse shape than we thought. Now I can rest assured that my transom is in good shape, and actually stronger where the bracket will bolt up due to an extra layer of plywood in that area. :)
