Thanks for the detailed reply. I'll have to see what the local scrapyard has for stainless angles. Its not inexpensive.

I assume the inside plate can be aluminum since it's basically funtioning like a giant washer. Would you think that a 6" or 8" square plate for each of the bolts would serve nearly as well, or would you stick with your recommendation of a giant plate? I think an 18" 6061 aluminum plate 1/4" thick can be had for around $40.

The old motor was bolted to the transom with 4 bolts. OK to bolt bracket to transom using just these four?
