Thanks!!
I had to do the transom in separate pieces. It was either that or take out a 5 brackets, the big one holding the transom to the floor. I did not want to drill out 20 or so rivets holding it to the floor. Instead I used 2 1/2" thick piece of plywood for the transom. The original was 1" thick. I made a cut 10" off each opposite side of the boards. Glued them and screwed them in. Seems very strong.
I still have to put spar urethane on the gunwales. I think I'll let them sit on the boat for a few days. Hoping they will somewhat bend to the shape of the boat before I take them off.
