    Yeah, the stock impeller is ok to use. Your rpm should increase to 8200+ with the VTech 8375 tune. You can purchase a Solas SRZ 15/20 at a later date.

    The stock RXPX prop is better than u think ..

    The more rpm you can pull the better they are .

    With just the 8350 tune, my PX was at 8400+. Assuming you'll be higher because of your mods, not a great move with stock valvetrain imo

    What other mods do you have? Which 8350 tune do you have?

    You will be fine with stock prop during summer but you will be all over the limiter once air gets cooler (@ sea level).

    To bring RPM's back down you can do one of the following:
    • Springs & retainers (great insurance policy)
    • Solas prop
    • Kick stock prop 1mm

    I've tweaked my stock prop every possible combination (6 times) and it did well up to 75.8mph (gps). After that it became a big obstacle, went Solas and never looked back. The stock prop is fine but it will require you to spin motor higher RPM to get the maximum out of it. Example - you can't comare brand A 15/19 with brand B 15/19 props. There is much more to it than the final number.

    If you have an extended warranty, I would stick to the 8350/8375 limit. If not, let the motor eat! These things come alive once you let it "spin"....but you must have proper supporting mods - injectors, logger, flywheel bolts & prop.

    On a mostly stock ski, the L13 will drop his RPM a huge amount (at or over 200rpm)....in summer it will feel like a pig.
