I have a 1992 Evinrude 60 with a bad lower end I was told that a 1993 Johnson 70 lower end would interchange and work on my Evirude. I am looking at the end of the driveshafts and they do not match the Evinrude has 16 splines and the Johnson has 4. Can I swap out the drive shafts and make the Johnson work?
