    Thumbs up SHO Nozzle On a GPR

    Here is my SHO nozzle I got from Island Racing. Carl recommended boring it to the GPR dimensions, so he did. I think this is a great alternative compared to the R&D or the Riva one. No real performance gain, just much better reliability than the stock plastic POS. and at a better price.

    And I might add, OEM Yamaha stuff is of a much better casting.

    Excellent and very true!...
    I found the SHO nozzle to be more precise when turning. I had the stock version. come back to this when you test and tell us how you like it...

    What was the ID before boring it?

    Is this the nozzle everyone was talking about from boats.net for $28?

    It's oval...87w x 90h. Yep they're cheap, but if you have a machine shop bore it make sure they understand how important it is get the hole centered. My buddy that did mine said he used a 3-axis lathe after throwing out the first one that another machinest F'd up.
