Lower unit compatability between older Johnson and Evinrude

[steveinsene]

Can anyone tell me if a lower unit from a 1994 90 hp Evinrude will work on a 1978 115 hp Johnson? Thanks

The driveshafts are different as are the engine crankshafts that they fit into. Shift rods have different part numbers.
