Frequently Asked Questions

  • How does a heavier intake grate improve hookup?
    The weight drives more water into the pump tunnel for more hookup in the straights, and especially the corners. The increased weight also adds weight down low for better stability.
  • How does this grate compare to other aftermarket intake grates?
    The RB300 uses the single scoop to load the pump more efficiently to reduce the air draw sound and feel. We have seen 1+ MPH speed increase over the WCOT grate. The WCOT grate has the double scoop loads of the pump well with water but has the negative effect of slowing down the ski heavily when off the throttle, like hard engine braking on a motorcycle.
  • Will my ski accept a heavier intake grate?
    Yes but understand that many older skis may have thread inserts which may become ripped out. This is a big problem even with the stock intake grate as your ski ages.
  • Is this intake grate legal for racing?
    Our RB300 intake grate is legal for racing. However, do your own research for the specifics in your class(es).

    I was able to receive one of these protypes!!! I rode my new 2k3 Yama SupaJetto 😊 and from stock to installing this grate, freestyle ride plate and the quick steer.

    My goodness the response and the instant power with less cavitation from stock is just night and day.

    I will be very interested to see if they will change it from original. I give it a thumbs up with all their products. 🤙🏽
