I'm amazed you can't buy such a thing off the shelf. All the aux brackets I have ever seen advertised are not things I would hang an engine off that my life might one day depend on. There must be a market for a simple bit of chunky alloy or stainless angle welded together to make a solid bracket to hang a little aux off where it can't fit on the transom.
