Ok, so let the PB be the filler instead of trying to layer mat on the hull and sanding that to get it completely parallel to the outside of the transom. If I use PB over the whole area you see in the earlier picture of the cleaned inside of the transom, is mat still required between the hull and the new transom plywood??
Clamping is a problem. In one of the first pictures you can see I have about a 4 inch wide gunwale over the top of the transom so it is not straight up like an outboard transom. That prevents running 2x4 clamps vertically The only way I see to clamp it is to clamp through the OMC hole, move up about halfway and clamp with holes drilled through the transom on each side, and then another clamping board near the top using the holes already there for the tie up fitting through bolts on each side of the transom.
For now, back to the transom to measure flatness horizontally across the outside of the transom.
