Fabricating something out of aluminum is a little more than I was thinking of, honestly.
I was just thinking of taking the rear wooden plate on my transom, transferring that pattern to another piece of wood with an added 2-3 inches, then adding a support immediately above the transom. Basically adding a new rear plate that could be bolted and unbolted fairly easily.
For reference here’s a picture of the back of my boat, along with my older sister and I on the Wakulla River
