Looking to beef this motor up a little bit. What all can you actually bolt on to these motors and pick up hp?

[99yam40]

You need to find a racing forum to ask that kind of question.\

I say buy a larger HP motor if you need more HP

A smaller boat.

Add a blower, nitrous oxide, etc. Maybe run nitromethane.

Be prepared for a reduction in engine life.

Are you looking for more speed or do you want to get up on plane faster? What kind of boat?
