Impeller size/pitch?

[idaho_forkman]

Hey, I've looked through the threads for anything on impeller sizes and haven't found anything that answers my question.
What size/pitch impeller is recommended for my 2003 Seadoo Sportster 4-Tech? Its non-supercharged 155hp. Looking at store sites I get contradicting sizes. WhenI do order the impeller, I assume there is a matching size to order for the wear ring?
Any info would be appreciated by this inexperienced owner. Thanks! Rob

call impros and ask them. They sell different brands and pitches. Tell them what you have and what you want it to do and they will hook you up.
