    Beautiful ski!!!

    For top speed gain and reduced cavitation go with the Solas 13/18 impeller along with the Lucky 13 adjustable pump cone. This will get rid of cavitation and improve performance.
    Be sure to shop in the GreenHulk store to save money. Use the discount code: greenhulk when you checkout in the store. This will save you 10% off the listed price of most RIVA parts, all WORX Racing parts and all Solas impellers.

    I have also listed all the stage 3 upgrades for you below.

    Thank you for your business!
