You will also need such.
I wound up using a stainless backing plate of the same footprint. That, in combination with the very thick transom glass lay up on the A-30 seemed to do the trick (the A-30 transom is small and thick, and held the bracket vane with ease and no perceivable flex). I only used a 2hp Honda 4s on the bracket, and I removed two springs as I couldn't easily compress the bracket downwards with such a light load on it. It worked extremely well.
