    Question on High Altitude Props RXTX - 2800 to 3800 Feet

    I ride between 2800 and 3800 feet in elevation. My ski rpm’s are usually at 7980 at WOT. My best top speed so far is a little over 70MPH. So I am looking at a 14/19 or a 14/17. Which will provide the best bang for the buck? Can I expect a 2MPH increase in speed?
    I am not looking to lose any low end torque.
    Thanks

    Your not far off at all. I would probably leave it alone or take a little pitch out of the stock prop.

    the stock prop is not bad, I prefer the solas props.

    So adding a different pitched prop won't give me any increase in speed?

    Doesn't really work that way... As you modify your ski you add more pitch to your prop, however... your RPM's stay the same... that's the key! Your right where you need to be... only 20 RPM off... I'd leave it alone
