Sorry I took a little long posting these pics but perhaps there still something useful that can be still taken away from them.
This is the transom before repair when I did my motor swap.
There are cracks and prior epoxy repair. I assumed that the transom brace and epoxy repaircame after the cracks.
Sanding the epoxy repair away I could see the two large cracks. The small holes for the trim was letting water in, which was early before any real damage was done as the transom is still solid.
I opened the cracks and the screw holes to allow fresh epoxy to bond.
Marinetex laid down before sanding smoth.
The new trim is heavy 2x2" aluminum angle stock trimmed to fit like factory.
If I were to do it again I'd go with stainless steal angle instead of aluminum like Trapper did.
Not that the aluminum has had an issue, it hasn't but if you can build it better...
Everything installed with 3M5200 sealing all holes. Three shims of aluminum stock the thickness of the angle piece were installed again with 3M5200, one long directly under the angle and two lower where it bolts up. I thru bolted the ends with stainless bolts and double fender washers to further add strength to the transom.
You can see the shims better in this shot.
Here you can see the transom saver plate all painted nice and remounted, the reinforcing extra bolts to the sides, and you can just make out the white traction tape I laid down prior to bolting it all up. The wide traction dresses it up, hides imperfections, and protects the repair underneath.
This was all done in 2015 and still looks as good today.
