I am buying a donor boat to get the engine, outdrive, trim tabs, and any other usable part. The motor that is in my 24 ft Reinell is a Merc 165 GM L6 with a 120/140HP outdrive(which I think has wrong gear ratio). The donor boat has a 302 ford V8 merc with 888(I think) outdrive. Loos exactly like my 120/140. So here are my concerns. How or what do I need to do for the engine support frames? Is the gimbal the same? What other issues should I be concerned with. Engine will be rebuilt and outdrive will be gone through. I will be redoing the transom. Thanks
