    No the plate is not below the shoe.

    Mai think I just need to find some smooth water and the speeds will be a lot faster. Even with the small chop it's not staying hooked up 100%.

    Maybe tweak the prop to get it to rev ... OutlawGPR looks like he has a similar setup but with a 14/22 prop doing 84mph .drop the nose and speed will lift it ...and it will handle the ruff stuff better too ..

    7,500 is not far off the factory limit
    Unless that was including the unhooking

    So if you run stock sho motor, stock rpms without a tune, is a 13/22 too big of a prop? Im only seeing 72 mph.

    my gpsho ran 78gps on a completely stock setup with no tune with a 14/21 and I am pretty sure it is sitting on the rev limiter.
