Impeller pitch for 98 GTX Ltd???

[halomatic]

Hey guys! I’m trying to buy a replacement impeller for my 98 GTX Ltd. The service manual (pg 09-02-2) says OEM pitch is 14/21. However, every time I search the internet for a replacement I find something different like 15/20 or 14/22. Do you think the manual is wrong? Or, maybe that pitch was updated to something better over the years? Not sure what the performance difference would be but maybe a 14/22 is close enough?

And another thing… Since this ski is designed for 3 riders, does the OEM pitch reflect that? I never/rarely ride more than single, so should that influence my choice of pitch?
Thoughts?

There is no standard for published pitch. So each brand is going to be different.
Contact Impros for a replacement and they will tell you which one is best for your application.
