    Stock Impeller Pitch

    Hey everyone,

    I'm trying to determine the pitch of the OEM stock impeller in a 2002 GTX 4-tec and
    a 2003 GTX "Triple Crown" N/A Wake edition. I've looked thru the shop manual's for
    both and no pitch info. I am starting to believe that they are the same pitch - whatever that might be.


    The "original" impeller according to http://impros.com/charts/nu_jet_avail_seadoo.html is a SS 4-bl
    but lists no pitch.

    Skat-Trak impeller chart shows "stock engine" is a 15/20 whereas Solas lists an 11/19 for a stock engine.

    Anyone know where to find the OEM pitch for those 2 machines?

    In my experience skat trak stock replacement impellers are not the same pitch as OEM, however they are close. I ran into this on a 99 xpl and 2007 rxp. Solas seems to be true to OEM on there stock replacement impellers. That being said I do not have experience with your specific application. 15/20 seems steep for that engine though.
