    Seadoo 951 carb intermittently dies/shuts off

    A little backround, 2000 carbed 951, fuel lines changed. Fuel valve, main filter/bowl, and internal carb filters cleaned.
    Opened mag cover and didn't see any broken gear/teeth from bendix floating around causing a short to the stator. All fuses good.
    Idling and midrange throttle runs good, no hesitation, no bog, nothing, then at full throttle "sometimes" it'll just shut off. It starts back up, runs fine again. Idles at 2900 on trailer and about 1400 in water. When it does not shut off, it will rev to 6800-6900rpm. What could be causing this?

    Possibly a bad DESS post or a bad key. If the start/stop button or the wiring to it fails it can shut off randomly also.

    If all that tests out, it's a long shot but try and run with the gas cap off. Just in case the check valve is stuck.

    Check your compression. It might be seizing. Remove the RAVE valves and look at the pistons.
