    Stacking wedges?

    I had bad luck stacking wedges! It required longer bolts and discarding my newley installed reverse along with steering and trim adjustments! way to big of a pain! so I'm trying this option I milled the nozzle seating surface and the wedge itself to a total of 7degrees this mod required no other mods and also while I was in the area I machined the trim nozzle to allow more range of motion! we will see how it performes ??

    If you go to GroupK's site, you'll find the they discarded the wedge and milled the rear of the ride plate to raise the bow.

    Sorry, I was surfing another page. Here ya go.

    2 SEATER HANDLING- There are no modifications that can make the 2 seater Polaris a good rough water machine. However it is possible to improve it’s ability to "deal" with rougher water conditions. Perhaps the biggest problem of the 2 seater is the porpoising. Based on out testing, the majority of this porpoising is caused by the nozzle wedge (between the exit nozzle and the vane case) that aims the water thrust slightly upward. Polaris installed this wedge to help lift the front of the hull away from the water (resulting in slightly higher speeds on smooth water). Unfortunately this same thrust angle serves to compound the porpoising problem. Some owners have reversed this wedge to improve rough water handling and reduce porpoising. The porpoising is certainly reduced, as is the smooth water peak speed (by 3 - 5 mph). Our approach to the problem is different. We remove the nozzle wedge altogether. This still makes for a "slightly" nose heavy ride that offers good control in semi-rough water. We then machine the ride plate in a way that lifts the nose of the hull slightly away from the water surface (on smooth water). The net result of this combination is reduced porpoising and improved acceleration, with no loss of smooth-water peak-speed ability. The angle and face of our ride plate modification requires considerable accuracy, hence the cost. Too little cut causes a noticeable loss of speed, while too much cut causes viscous porpoising at all speeds.
    During all our 2 seater tests we used the stock scoop grate and sponsons. To date, we have not found aftermarket replacements that offer a significant handling improvement and still maintain the good peak water speeds of the stock parts.

    Mocked up the 8deg wedge and it fits fine. The nylon water tube bends just nice like. I see no reason the reverse will not work.
