    03 GTX SC with Solas 12/20, what RPM's?

    What RPM's should I be turning on this ski?
    The only mods are the impeller and a Worx intake grate.

    I rode it again yesterday, and it's only turning 7100 rpm's.
    Am I better off with the OEM impeller?
    I have a brand new one that I could install if it will pick the speed up a bit.

    All aftermarket props are not 100% perfect out of the box, you need to match them to your ski...you will need to repitch...

    My father's old 04 GTX had a full stage 1 on it, minus the prop...So we put the prop on, and he went from 7600 to 7300ish...He was going to rip the prop off, but we checked the prop and all 4 blades were different...So we trued them up and then pitched it a little, and got his rpm's to 7550-7600 in the heat....Ski was completely different then


    BUT going from 7600 to 7100, thats a LOT....what is your current oil level?

    Im only at 7000

    I am turning 7000. This is with a 2 degree wedge, OPAS blockoffs and a riva intake grate. I was turning well over 7300 with only the blockoffs. After I added the wedge, grate and prop; I started turning only 7000. I know that I should have added one at a time to evaluate but you know how that goes.

    Oil is exactly at the half way point.

    you will need to send your prop off to somebody such as IMPROS and
    tell Dave your speed (hopefully gps) and RPMS. He will then
    pitch your 12/20 accordingly.
    Just put in the stock prop till you get it to and from him.
    You will be very happy with the Solas over the stock prop once
    you get this done..
    Just be patient.. You would think that when you spend
    all that $$$$ the product would work out of the box...
    BUT in this performance world, there's too many variables to
    get a one size fits all product.
