I used coosa board for my transom. It was the blue water series and 1 1/2 inch thick. Good stuff - very easy to work with. I first reinforced the corners (hull sides and bottom) with two layers of 1708 tape. Then two layers of 1708 over the remaining transom skin. Then glued the new core to the reinforced skin. Following that I used a layer of 1708, 2408, and 1708 respectively. Finally I added a knee to the center stringer and tied the stringers back into the transom. Everything is solid now and new motor should be going on soon.
