    2009 Yamaha FX SHO Bad Idel and No Power All of a Sudden

    Today I took out my Wave-runner for the first time and it started right away and ran fine for about 20 MINS. After that I noticed when I gave it gas it would bog a bit but still get up there. Then it lost power and stalled. After 5 Mins it would start again but idle HORRIBLY and then shake while idling, didn't sound right at all. If I gave it gas it would bog and sputter and I had to limp it home. I changed out the plugs and the issue is identical. I don't know what the issue is but I fear I blew the motor. The oil is clean but has some white stuff in it. Below is a video of the issue.

    I have all the basic boltons, a larger intercooler with HKS BOV, and a C1-11 Wheels. Last I rode it it was perfectly fine and ran like a champ. Today it ran OK, not perfect and then died. It'll idle poorly but that is it.





    Any and all advice would be greatly appreciated.


    Regards

    Can you explain more about the "white stuff" in the oil? Water in the oil can make it look cloudy white. Or are you talking about little white particles?

    Cloudy for sure. I read it is moisture. Not a crazy amount but it is there.

    I will leave this to the experts, but my fear would be a blown head gasket.

    mine did a similar thing, it was the sensor under the exhaust manifold, it corrodes and throws a fault code. sounded like a big lumpy cam

    maybe take it to a dealer and see if they can check the ecu for any codes.

    I can't even get it to run anymore. I don't see any codes or issues and my oil is milky so I am guessing a blown head gasket. It had power but it was gradually losing until dead.
