Does anyone know if I can use a lower end from a different HP engine. Like a 90 Hp or 115 Hp to replace my 75 Hp one? They look the same but want to be sure.
Inline fours and sixes from 65Hp to 150Hp in the 60s and 70s and well into the 80s. I'd stick with one from an inline four for the best chance of the correct gear ratio.
