I have looked and looked and cant seem to find the answers I am looking for. We have an 83 OMC 120hp engine that runs great, and then we might possibly buy a boat that has a 83 Merc 120 hp engine with the Alpha Drive. Both motors are form the same year, and they are both a chevy inline 4 design. The merc has a cracked block and has water in the oil. Can the Merc be taken out and the OMC put in its place? I know the Exhaust systems are proabably different and the harness is proabably different. What I really need to know is if I can bolt the drive up to the OMC motor, and if the motor mounts will work with the OMC motor. I kinda need to know quick since the boat in question is being sold so cheap and might be gone to soon.

Look at both engines, if they look the same they will swap.
