    Can no one help with my Kawasaki stx 15f?

    It rans great until it gets in the 40's mph then it just cuts off, if you just stop it just starts right back up and you can gun it until you get in the 40's. I was thinking there is to much water in the bottom of the ski and its splashing on a sensor or something, tell me what you think. Thanks everyone

    Why is there water in the bottom?

    Have you done a compression test?

    I have 2 jet skis on the trailer and if no one is with me I can't tip the trailer to get most of the water out then I clean the engine really good so more water gets in, and no I haven't done a compression test. It was was running great for like 2 days after I had the spark plugs changed then it started

    Check for electrical shorts, buy a siphon or a length of clear plastic tube, no reason to leave it wet. Check the fuel pressure as well.

    Leave the drain plug out when you pull the trailer up the boat ramp and it should drain the water out.

    Remove the seat and put it in the water and watch to see where the water comes from.
