    MSX 150 Problems.

    I have an MSX150 in with the engine warning light flashing when on the water. Revs limited. Access to digital wrench is non existent in this country.
    I removed the intercooler and piping to find milky oil present. removed the 2 map sensors and found one out of spec. Ordered and installed 2 new sensors from here http://www.worldcarparts.co.uk/Defau...ProductID=1231 same spec as Bosch OEM ones but cheaper.

    Also found the baffle plate in the oil tank
    had come loose so i rectified this.

    All back together now and the engine check light is on once I start the ski.
    (Only came on before on the water).
    It now starts fine but idles very high, 3000rpm and if i floor the throttle it will rev to max and remain there, I have to shut it off immediately.

    I have rechecked all hoses and sensor connections to no avail.

    Any help is appreciated.

    No need to panic Steelroe, nothing is wrong, once you put it in the water it will settle down. As a precaution all ways put in reverse when you are out of the water this will hold the revs to a maximum of 3400 if it decides to take off. This is a known issue with the Weber powered MSX's

    Thanks for the reply.

    Original problem brought on the warning light solid.
    Now the warning light is flashing. On a few problems will make it flash, overboost being one.
    Going to take it to water later today and how it behaves.
