Pic 1 & 2 shows where the transom started to come apart from the increased stress.
Pic 3 shows the brackets I made to prevent the transom from pushing 'into' the boat and continuing to pull the transom apart. I am also going to run a piece of angle across the bottom of the transom board to stiffen it and help transfer the force to the brackets and sides of the boat.
Unfortunately, I don't have an tig welder with AC (yet) so I tried some of this
stuff but my Mapp torch wouldn't get the aluminum hot enough. Just too much surface area to dissipate the heat.
We'll see how well this all works!
