    Questions About Prop Pitch

    My prop now is a 11/19 and the stock one is a 10/18. My rpms are about 7200. Before I was getting 7400. So would I get more speed with less pitch or maybe I can tweak it? Also, I saw a diagram on tweaking props on here. Does anyone have that?

    You should get max mph with the higher rpms provided you stay off the limiter. I forget what the limiter is on the N/a Skis. 7600???

    yea I would get it to about 7400-7500 if your limiter is 7650

    The colder it gets the more rpms you will have so thats why I say 7400-7500

    I only have experience with supercharged skis but you can pitch the prop to what ever you want. However the root angle of the prop might be different.

    Example is I can bend a 15/21 into a 14/19 but it wont be the same as a unbent 14/19 due to the root angle being different.

    Ok in regards to tweaking.... If you don't bend each blade perfectly, will the prop vibrate excessively? Also I saw a picture on pitching, does anyone have that?

    close maybe do 1mm and try that see what you get. It might be different for you with a non supercharged ski.
