    You would notice a big difference. There are quite a few upgrades available to you.

    The green charger impeller would be a good impeller if you are just starting out and don't have many mods. You will notice a real nice difference with this impeller.

    The Riva stage 1 kit and the green charger impeller would get you off to a real nice start.

    The Riva Stage 1 Kit comes with a new impellor..You may have to tweek it according to were your RPMs are at..Here is what all comes in a Riva Stage 1.
    Add a Greenwheel to this setup and you should be a 72-73 MPH ski with great acceleration..

    Riva RXP Stage 1 Kit

    $724.50

    All components purchased separately total $789.80. When purchased as a kit sale price is $724.50. No other discounts apply. Kit Overview: This modification delivers the maximum level of performance through easily installed air intake and pump enhancements. No internal engine modifications are required.
    RIVA RXP Power Filter Kit is installed. Power Filter provides greatly improved acceleration and a 150~200rpm increase by replacing restrictive stock intake system. Features a large 3” diameter intake duct and oversized K&N filter element that feeds your Supercharger with a steady diet of cool air. Installs quickly and securely using a silicone coupler and sturdy bracket.
    RIVA RXP Pump Wedge is installed between pump stator and output nozzle. 2-degree wedge trims up your pump nozzle raising the bow of your craft for less drag and more control. Substantially improves top-speed and handling.
    Solas Concord Impeller is installed. This impeller is specifically pitched for our Stage I RXP package using a pitch block to ensure accuracy. Billet impeller cone is included.
    RIVA RXP Top-Loader Intake Grate is installed. Unique reverse wing design eliminates prop spin and cavitation while delivering improved handling and top-speed.
    NOTE: Sea•Doo and RIVA both strongly recommend the use of premium octane (92+) pump fuel in your craft.
