Hi, I have 2 Johnson 30 hp motors, they are both the same year however one is a long shaft the other is a short shaft . the long shaft motor runs extremely well and has electric start, the short shaft motor is pull an is very unreliable. I have a 1968 boston whaler 13 with a 15 inch transom, I would like to swap the shafts. Can this be done and if so how hard is it.
