2-Piece Rear Main seal applications (Pre-1990)

Crankshaft Compatibility by year: (this is based on my research and the OMC parts diagrams)

Works on 1968-1985 120hp 2

but this was pretty common on all of these that I have processed & seen because of how they oriented the soldered wires coming off of the tab connections in conjunction with how the wires were typically routed

Generally used 1990-1998
