    07 prop upgrade advice

    I just had a driveshaft on an 07 strip and need to replace the prop. The ski has:

    255 super charger
    42 lb injectors
    4 in intake
    r and d grate

    Should I go with the 15/19, or the 15/20? or something else.

    The ski is running the stock ECM and I don't see it going to higher RPMs in the future.

    Thanks for the advice,

    You haven't said if its a P or a T. If its a RXP I would go with a 15/20r and if its a RXT I would go with a 14/19r and dial the impeller in from there. In either case I would also throw a wedge in there. JMO Good luck
