Mercury Kiekhaefer Outboard Mark 78 43-26215 43-26214 Gear Set Forward Pinion Bolt Set This would have been compatible

This would have been compatible with all of the standard GM & Ford 2

Some wear on some of the teeth

The coils & points & condensors on this look very new

possibility it might have been used on other models 1971-1975
