    Impeller help 750sx cavitation issues

    Skis is the one in my sig. Cavitates like a mother, still using the stock prop. I have a Solas in my spare pump but it's pretty beat up and it might still be the same pitch.


    I'd like to get more top end out of my rig as that's what my motor is built for. What's a really high pitched prop that will still give me good overall performance?


    Stock prop pitch is 9/17. My buddy suggested something along the lines of up to 20 degrees or more.

    If you do have the stock impeller in your ski then it's an aluminum 14/19. The sxi had the first stainless impeller for a 750 and it was a 9/17.
    Never argue with an idiot, they will drag you down to their level then beat you with experience.

    I have a solas prop in my spare pump but it's not in the best shape and I'm not sure what it is.


    I just want to be able to make use of the top end of my motor

    I have a nice standard Skat 12/20 that should be a good match for that setup, ill give you a good deal on it. Otherwise if you want something new, I love the Solas Concord 12/18 that I have on my sxi.

    PM me what you'd have to have for the 12/20

    Turns out the stock pitch is 14/19 according to Impros. They call for a 13/18 or 9/17
