    Pump Wedge Question

    On the RXP, my best speeds are obtained when the trim is at two clicks above the mid point of the trim. So there is more trim available if desired.

    Anything above that, you scrub off a bit of speed.

    So with that in mind, why would you want to install a wedge?

    I assume a wedge points the nozzle a bit more skyward right?

    Are people using a wedge on the RXP? or are they just installing it on the three seaters that do not have trim..........


    Thoughts?

    A wedge is closer to the impeller so it directs the water more efficiently. The farther from the pump you direct water the less efficient the water flow. Thats why with the RXT we flip or modify the steering bushing to straighten it out.

    Are people using them on RXP's though?

    mostly preference. You gain speed but your nose rides higher and can cause porpoising at high speeds. You then have to put on pro or RE blockoffs , change the sponsons or do trim tabs to calm the porpoise. Mostly I've heard the RE, pro blockoffs have stopped it. I believe it's 75+.

    I will never go naked on my pump again. I hate crashing waves or slight chop instead of slipping over them with the wedge.

    I say get one if you have a aftermarket grate
    If you don't have an aftermarket grate then I say get one then get a wedge

    The wedge installs before the venturi.

    You scrub speed above 2 notches above neutral with or without the wedge. I believe it's because after that point the angle between the steering nozzle and venturi becomes too great. That's when you start to lose speed. Sorry I can't give a more scientific explanation.

    Grngoblin, as for your question about conditions the wedge is fine in chop. I notice no difference so long as you have your trim set correctly. Realize that without the VTS extension rod, when your display says your trim is all the way down you're actually at neutral trim.

    I will say the wedge did nothing but help me. You will gain at least 1mph on top end with it.

    If you're worried about trim in chop then get a VTS extension rod.

    I am a supporter of the wedge.
