    15/22 Impeller ?

    I currently have a 2006 RXP with the mods below and 70 Hours and hit the rev limiter now. I just recently purchased a new impeller ( Got a great deal on a 15/22) My question is this prop to tall ? I am not too concerned with giving up a little acceleration I just do not want to put too much load on the motor and risk damage. Please let me know your input.


    Rear Thru hull Exhaust
    OPAS Delete
    Riva Intake Grate
    Riva rear Intake ( Not installed Yet)
    15/22 Impeller ( Not installed Yet)


    Thanks,
    Nick

    yes that prop is to tall without and external intercooler and bigger SCer...with your setup you would want to go with 14/19r

    Yes, it's too tall. You will need to make some decent power mods before you can spin that prop to 8k+

    I will be working with Speed Freak to re pitch the prop and get the set-back mod. I will let you know how everything works out !

    your motor will not have any damage at all..it will be fine just your rpm will be a little lower sence am guessing you have the stock 6 lb supercharge..lost of acceloration but better top speed if your running on flat flat water..should be around 7700 - 7900 rpm.. the rear air helps alot! if you could get your hands in the future on a rxp-x green injectors and x supercharger, the setup should be perfect going at 8100 rpm and around 75 mph
