    Gpfzr pump issues

    WOULD BE A GOOD IDEA IF I PUT DOWN THE PROBLEM I AM HAVING.
    THE SKI IS CAVITATING BADLY AND HITTING THE LIMITER ALL THE TIME.
    THE SKI HAS REFLASH-RIVA COOLER -INTAKE UPGRADE FUEL TUNER THERE ARE NO ISSUES WITH THE MOTOR JUST POWER TRANSFER TO THE WATER??

    Probably going to need 158mm or bigger to get any kind of holeshot due to the instant torque these things make.

    What grate, shoe setting?

    Shoe sealeed?

    Rpms on top?
