Whilst it's a bit off-thread with regard to permanent installations, we have a very successful "emergency" outboard bracket on Spring Fever which may be of interest: -
SF is fitted with an inboard MD6A, but we also carry a Mercury 3.3hp outboard for the dinghy.
Our boarding ladder is fixed fairly central on the stern (it's a four or perhaps five step model, which hinges in the centre) and we have constructed a 6"x8" board which is clamped around the bottom tread.
This makes things more comfortable for climbing out after a swim, but also means that if we hinge the ladder by 90 degrees and secure it with a lanyard to the pushpit rail, we then have the facility to clamp the dinghy outboard onto the back.
We've tried it twice, once to move berths in a marina when the MD6A was out of commission - it manouvred better than usual Also once at sea, when we were becalmed and drifting aground after the MD6A had overheated - it pushed us along at 2.5knots very easily, until we found some wind to sail.

Steve,
What do you mean by the "usual fibreglass precautions etc"? Someone
please enlighten me in my ignorance?
I have a bracket mounted on the port side that worked fine for many
years with my Honda 9.9 longshaft. Tilted and raised the motor was
always clear of the water. Unfortunately last fall an @$$#&*% in a
large powerboat thought it would be fun to run right past me and try
to swamp me with his wake and the bounce bent the bracket which I now
need to replace.
