Apologies if I posted to the wrong thread. So I have a 1990 bayliner Capri with the 3litre inline 4 mercruiser alpha one. Atleast one seal is done, bad noise in reverse (only can hear it out of the water) and grinds going in gear (tried to adjust cables no luck). I acquired a boat from a friend with a interior that's done. But it has the 4.3l V6 mercruiser and the lower unit was rebuilt before it was parked for years. What's the chances I could direct swap the motor and or atleast the lower unit. It's around the same year. Any input is appreciated
