After two months I got the outboard bracket back from the Stainless guys. The initial design of the bracket had two mayor flaws: the first was the thickness of the bolts used to attach the bracket to the transom and the second the ability (or lack there of) to keep the outboard set at different heights. The outboard is mounted on a sliding mechanism which was held up by a line fixed to the stern rail. Not only was this highly inefficient and difficult to work with, it was also dangerous.
I therefore had the old bolts replaced with 12mm stainless bolts and had holes laser-cut so that I can adjust the height of the outboard by inserting a “key” in the new holes. I have had some time to experiment with this and it seems to work much better than before.
