    you gotta see this to beleve it

    up here in michigan we had a cold front come in and it was 85 last weekend
    and droped to 70 deg today.
    on sunday I ran a new personal best of 73.3 mph on a 1/2 tank low humidity at 7950 rpm,
    TODAY 70 deg 50perct humidity I went 74.3 on almost full tank see pics
    at 8050 rpm
    and at 1/2 tank went 74.5 at 8050 rpm
    my prop is a little to tall keeping me under 8150 rpm limit
    but in 60 deg weather I think I will go faster
    see my mods at the bottom and I also added a vortech impeller
    with a fresh stock ac clutch that i built with no shims just stock

    YES I WAS THERE. KEVIN WAS FLYING!!! He was a consistant high 73.+ on a full tank and ran 74.5, 74.3 and 74.? numerous times with half tank. IT was no fluke. The temps outside were cold, but hell for what he has done to the ski it was flying. No intercooler and tons of free mods.... That's almost up to the speeds of a Stage 2 rxp.
    CONGRATS! KEVIN! time to change your signature

    Frank actually got his rpm's back up to 8450 bouncing on the limiter but was runing too small of a prop for top speeds (14/18 ).

    I went 76.0 on his boat bouncing on the limiter so he needs to put his 14/19 back in and see his speeds increase back to the normal 78-80 range. He was runing a brand new stock 2005 clutch and supercharger this time. His whole problem before was that stupid HD clutch and runing rich basically. The weather sure plays a big part with that rotax racing ecu.
