Rich, the Volvo drive is on the Scimitar, it's the original equipment. I'm going big block and Mercruiser Bravo One. I did just notice today that the motor spins standard left hand, but the prop spins opposite of the Mercs, thought that was interesting. no idea what kind of power this Volvo drive could take, but I had enough of no trim and reverse locking mechanisms when I played with older outboards!
I know the Bravo will take what I intend to throw at it, and parts are common. plus, I have a much better understanding of them. thanks for the offer of diagram assistance, I'll be sure to let you know if I need it. as long as the bolts don't fight me too hard, should be able to get this out of my way quickly.
