The engine mount bolts on top of my transom were sinkng in a bit. After determining the wood in my transom was still solid I decided to just reinforce it. There were also a few holes from a previous motor which I sealed up with 3m 5200. The current motor is a mercury 60/40 jet.
There are several 3/16" aluminum plates under to match the thickness of the knee brace bracket. I then ran 1/4" aluminum across so that it rests on the knee braces. I sealed the holes with 5200. I decided to use two plates so that I could add them seperately and didn't need to take off the motor. Definitely solid and I don't have to worry about the bolts sinking. The hardest part was drilling he 5/8" holes in the aluminum.
