Johnson 25 part compatibility

[puretic]

How compatible will the parts be between a 1978 and and a 1980 Johnson 25?

 

[timguy]

They should all interchange.

Well----Many parts will interchange.------But there might be an issue with crankshaft splines.----Different driveshafts.

Darn, your good, Racer. I think there was a change in the water pump drive key in there.
