I have an older BW Nauset that I prefer to keep an older engin on, I presently have a 1984 Evinrude 75 Hp that over the years I have purchased extra parts such as a a starter , tilt and trim wiring harnesses so I could always maintain this motor. Well the motor had other ideas and blew a hole thru a piston, so I recently bought a 1988 Johnson 70 hp. I always thought that the parts from the early 80's Evinrude/Johnson motors were interchangable between years close to my 1984 such as starter,carbs and most and most parts. Now I have found out that the block and major parts such as splines are slightly different on the new motor from the 1984 year , but wondered if someone could tell me if parts like the carb, starter , tilt and trim and bottom end are interchangable between 1984 and 1988
