In any case you still can't trim the drive like a Mercruiser. The OMC Stringer trim system (if equipped) allows you to trim the whole engine and drive as a unit, but how far? The Stringer 400 that's in my boat has no trim system to begin with, the drive is either up or down. For a boat made in the 80's where tilt & trim was standard on every Mercruiser produced since the early 70's OMC was late getting on the bandwagon.
Ditto. I can't imagine a scenario where Mercruiser wasn't an upgrade. Leave it to B-liner to put a four banger in a 21' cruiser. Yah sure, you can get on plane... with a 10 pitch prop, no friends, no gear, no beer, and no fuel on board... with a tail wind. Jeez.
I took out a Buick V6 and Muncy Gear Works outdrive. The Stringer is an upgrade, and I don't have to totally rebuild the transom. My 800 has power steering.
Hmm... The Stringer is an upgrade... you don't hear that every day!
And just an observation (no response necessary) if you haven't
already totally rebuilt the transom in that '63 boat... you should.
