    Cavitation on holeshot with VXR?

    I have been reading about ways to decrease cavitation on hole shot with the vxr.

    I am wondering where people are standing, or sitting when they take off.

    In the absence of having a variable trim I have found i need to get my weight forward, leaning over the nose.

    When I get my weight forward, I can pin the throttle off the launch without any cavitation whatsoever.

    As the ski accelarates, I find I have to quickly shift my weight to a more neutral, but still slightly forward position.

    This seems to work well enough to keep up with most of the stock SC skis that I run with.

    In any sort of chop it takes alot of work to stay hooked up, but it is doable to a point.

    Thats pretty close mate.

    I stand neutral..as ya punch it I yank the bars to lift the nose, then I throw my weight forward to get the boat flat as fast as possible. Its kind of all one fluid movement. Once you have a trim trigger fitted you can do this more seamlessly...Its worth practicing over and over.
    Just leaning forward buries the nose too much.

    Once on top get as far back as poss.

    Id check the clearance of the prop to housing...Im at 89 hours and had excessive clearance....I did suck a rock through it last summer in Florida....a little dink on the leading edge of the prop but I dont think any damage to the "wear ring" but just wear on the outer edge of the prop and housing....just a thought.....
