Man I've seen that "rotten wood" visual on mine and it's not pretty. I poured my transom so I did not have to deal with the wood. If I did I would use two layers of 3/4' marine plywood or composite. I would then make a cardboard template(s) to fit in as tight as possible, so cover all the corners.This may not be the best way to do it, however I would place each sheet, front and back sheet, in the cavity in two pieces. Confusing I know. I would cut the sheets vertical at 80/20 right for one and 80/20 left for the other. You can then trim them to fit much tighter and fill all the gaps. Doing it in two pieces would enable you to wiggle the wood all the way to the sides and top....trial and error well before glassing. The middle of the transom would be solid 1 1/2" with the seams on opposite ends, one seam on the inside piece and the opposite seam on the outside piece. Lots of 1708 and epoxy resin and there will be no flex. As it is now you could never get a real tight end to end...top to bottom coverage with a single solid sheet of plywood. Confused?
