Compatible with most MerCruiser GM engines 1983-1986/87/88sih using circular cast style coupler that mounted to the crankshaft bolts

Please Close-up Pictures of gear teeth

Generally used 1982-1996 (mostly just the early stuff but referenced in the newer parts manuals) on V6 4

From my research it could have possibly been on something with a Chevy / GM 283 engine as it seems like it's some sort of 4-barrel carburetor
