    witch prop or repitch

    Hi guy's.

    Got a 2008 gtx 215 and I'm going to install a x charger and 42# injectors.
    In order to get full potential from my mods I know I will have to get the right prop. Witch one should I go with or ...can I just repitch mine?? The sotck prop pitch (according to the shop manual) on a gtx is 10/21 and stock prop on a rxt-x is 14/25. Is it possible to get up to 14/25 from a 10/21??

    "Witch Prop"

    15/20 bent to your satisfaction!

    The root angles are going to be different on the OEM vs aftermarket

    You will want the 15/20R impeller for your setup.

    The 15/19 is a 3 blade and is used for higher modified skis (Riva stage 3 kit)

    You will want the 15/20 with your planned mods. It's a 4 blade impeller.

    I think a 14/19 would be fine. Depends on your weather, altitude, etc.
    Don't want to argue with the experts , but I think you'll be
    "custom" pitching anyway. If you can find a 14/19 in good
    shape even used, that would be a great starting point
