Seriously, I mistakingly thought the engine was small enough to be a clamp on outboard, got my mucking threads fuddled.
I don't like stainless for clamp on outboards as the clamps don't 'bite' into the surface and can move about or even slide off.
For a bigger outboard I'd still consider Ali as it's easier to work with, and it would come down to how much cutting, drilling etc I needed to do.
Obviously the Ali would need to be thicker than Stainless so weight wouldn't come in to it.
It would also depend on what material I'd scrounged out of a skip lately.
