SX/SXi/SXi Pro 750 sxi pro impeller

[Undert8ker]

I have a friend trying to get more bottom end out of a 2002 sxi pro. He is wanting to change the impeller. Everything I read says 9/17 swirl. We took the pump apart and it has a 8/16 swirl is there that much difference in them?

He already has a better impeller for bottom end than a 9/17.

That was my thought but not sure. The ski has a a ton of mid to top end but it also has a factory dry pipe with ecwi, where my ski has a wet pipe and a lot better bottom end power.

Find an 80mm Reduction Nossle. Will get the most out of the Stock Prop. All the 92-94 SX models had them STock, and many sitdowns as well..
