I have a 69 13' Sport and i need to know if a Johnson 40hp with a 15-16" shaft will work with my hull. if anyone could help that would be great.
Thanks

If your boat has the notched transom then you need a short shaft (15) motor,

I have a '71 13' Sport and just bought a '92 Yamaha 40hp. The shaft is ~21-22". Is it possible to use this motor?

Do you have a notched transom? If so, you would have to use a transdapter. If not yes you can use it.
