    150 goes instant engine temp light and zero throttle response

    After weed plug up, pulling the cone and cleaning the tubes I can't seem to get the ski to run without going to a instant check engine and engine temp. Any ideas of a sensor that may have gone bad?

    How is the coolant level? There are two sensors, one is on the exhaust manifold and the other senses engine temp. The exhaust sensor can be unplugged as a test.

    I will try. Thank you. Before I start pulling stuff apart is there any insight you can give me about the locations of these sensors

    You (or your neighbor) overheated the ski, right? Have you run a compression test yet on it?

    Do you still have the shutoff issue?

    The exhaust manifold overheat switch is on the rear of the manifold... above the oil filter. A single wire/connector goes to it. You can unplug this to test. If the overheat indicator goes away... could be a bad switch.

    The coolant temp sensor is between the intake manifold runners... in the coolant rail. This is a sensor returning temp values to the ECU. You can not unplug this to test.

    Cheers!
