If you are older - I am 73 - you might like the Seawise davits that has your motor permanently on a bracket. The motor is brought up and off the dinghy when raised and down and on the transom when lowered. You need a swim platform for these davits which can be manual or electric. Some use a cordless drill to raise and lower the dinghy with the turn handle (manual).
I replaced my swim platform from roughly 14 inches to 18 inches. Extra brackets - went from 3 to 5 - to reinforce the platform so it could take the dinghy/davits and handle the stress. A local aluminum manufacture made the brackets for me.
Seawise davit system:
Something like a Highfield 9 1/2 RIB will fit nicely on your boat, I have something like that with a 10 foot beam, your beam is one inch shorter so its nice to have a bit more length with your dinghy if you can do it.
