    They claim it will give +1 mph, are these claims valid ?

    GPR Hydro Force Steering Nozzle - Now Available

    R&D's new Hydro Force Steering Nozzle for the GPR is a direct replacement nozzle. The new lengthened design delivers a full 1 MPH speed gain over stock. The adjustable pivot point position improves the turning radius allowing you to carve tighter turns with a more positive feel. Improved performance through speed, acceleration and handling.

    Again, I guess every ski is different.

    I personally use one and I did a back to back on "my ski" and I seen a gain with the extended nozzle. I put the stocker back on and lost it. Put it back on and gained the speed back.

    I also prefer the aftermarket nozzle because of the strength vs. the plastic stock nozzle. I've seen one that has broken B4. Ask John Abbott.

    I also prefer the way it turns with it on.

    I don't trust plastic at the speeds we are running and the amount of thrust that is exiting that nozzle.

    my experience is no

    that said, I use a protec nozzle or the R&D auto-drop simply becase as already mentioned the plastic ones break (especially when jumping if you hit bottom)

    I've never had steering cable issues with running my for the last 5 years.
    As for speed differences, i have never did back to back testing. I do love the way it helps the boat turn.

    I have been considering purchasing this for safety reasons and for the fact I think there is enough material to machine them for the Skat interchangable rings.
