    New best today! hull mod is the truth

    Just tried out a different nozzle and modded the hull with a buddy of mine.



    Only got 4 passes in of which my last pass i could hold for a full pass, due to no wake. but this is at 8650ish RPM it would spike 8700 but not hold it. Half a tank and me (295lbs)




    Ill get someone lighter on the ski and shoot for 89 next week.

    Best tip would be don't try it yourself as you can make pump more prone to stuffing and can make your ski slower and less stable if you fuk up. There are some pros at it that have proven results.

    85.5 at 8600 rpm. Only thing i changed was to an 87mm 5 degree nozzle and hull mod. SKi picked up 50-100 rpm from the nozzle, i have some more things my buddy wants me to try.

    The stock 85mm 3 degree i think is the stock SVHO nozzle. Apparently what jerry said was that this nozzle slows you down, i wish i would've brought the other to truly test back to back and see but the weather was shitty and only could get 4 attempts in.
