New to outboards so this may seem like a stupid question, but how do you choose a prop for an 84 Johnson 90hp, such as pitch and blades? I have a 15'8" KingFisher Tri-Hull. I would like some more top end speed.
I was wondering the difference between a 90hp and 140hp Johnson V4 from 1984. They seem to have the same bore and stroke. Is it the carbs? I have a 90hp, but want more power. (As always!)
