    pro 785 impeller

    What is the best impeller to use on a pro 785 with ADI heads, hot seat shortened water box, red tops??
    I pulled my pump off the wrecked ski to start transfering stuff over to the new racing hull, and found my old impeller is pretty narled up on some of the leading edges,
    I have a new polaris # 5131366 17/23 that came with a 6 vain s/s stator and a 10.5/16.5 skat track that was in a box in the trailer,
    thanks,

    You can have that damaged impeller refurbished by Impros for less than $100 and it will be just like new.

    I know, I was just wondering which pitch was the best for bouy racing?
    I will get this one off tomorrow at the shop, I have bowman propellers in town that do pretty good,
    thanks,

    That 10.5/16.5 will pull like a horse and let it rev if everything is tuned right. According to PolarisRacer it will top out around 60 but get there fast. Try that one, or a stock Polaris Scat 12/17.

    Without any aftermarket pipes... 10.5-16.5 or 12-17. Make sure you are using a LONG blade impeller for better hook up

    I have my old impeller off and it is a 11/16 Skat trak I was only getting 7750 rpm with this one,
    should I go with the 10.5/16.5?? the only time I get to wide open is on the start and the front and back stretch,

    The grease really smelled like rotten eggs when I pulled the tail cone off, PHEEW!!


    thanks,
