Well finally got the transom out. I'm guessing I am gonna find some corrosion when I clean the no less than two tubes of silicone out of there. He had the z bar siliconed to the boat and the transom siliconed to it and the aluminum skin. I set up two block and takles so I could alternate pulling more on one side then the other to try to break it loose. The wood is trash. It good enough to use as a template
