My hull is too far to get to as well, so I can't help you with dimensions, but I'd like to share how I solved the issue of protecting the transom. I'm using a trolling motor, but the way it clamps to the transom should be similar enough.
Instead of reinforcing the boat, I added some padding and reinforcement to the clamp.
I took a sheet of the felt-padding that is sold for gluing under furniture (it's about the size of a small postcard) and glued it on the inside of the motor side of the clamp. That left the two screws on the opposite side that normally end in two flat cups. I glued a strip of wood across both cups to prevent marking up the inside of the motor well and to distribute the load further. I didn't go much outside the existing dimensions, so the clamp still fits with room to spare, but the overall surface area is now double what it was, and the wood is soft enough to not dent or scratch the fiberglass, like the metal cups might have.
