    Dean,

    couple of Questions to help us get to the bottom of your issue...

    -Does the ski do anything at high speed?

    -When on the trailer, is the Jet pointing straight when the handle bars are straight (use verniers to measure the distance of each inner side of the steering nozle toe the jet nozle)

    - Are both your sponsons stepped/level etc the same ?

    - Is something dragging under the hull, ie: one trim tab lower then the other? or in take grate uneven?? (try a different intake grate)

    - Check the Leo hole shot kit is installed correctly and nothing is dragging under where the top and bottom decks are joined

    How long has the ski been doing this for?

    ok...the ski is fine when the engine is running and for high speed,well i havnt been able to have it do that yet.

    hole shot kit is fine..

    handle bars are fine and straight with the nozzle..


    trim tabs look good....

    ill wait to i get it back from danny and check the other things...



    i was thinking that it might have water in between the to hulls...

    water stuck between the hull will make it sea saw/rock side to side not pull to one side....

    ross posted a thread on how to fix that water issue recently but i doubt thats your problem

    Dean, you're probably better off posting this in the Yamaha section then the conversion section... probably going to get better responses over there I'd say.

    It's normal. Some skis go to the left, and some to the right. The ONLY thing I've seen effect it, is where your sponsons are sitting on the hull. Look underneath them, and measure from the last step to the bottom of the sponson shelf, on each side.

    If you are doing stepped sponsons, it could easily go either way.

    Ski's aren't made to go straight with the pump not pushing them.
