    99 Polaris Genesis, over heats after slow driving

    99 Polaris Genesis, fuel injected, 1200cc

    It gives me an check engine/overheat notice after I have been driving really slowly in the water or shutting down in the water (when taking a break).

    Otherwise, it runs fantastic, and the overheating has never left me stranded *touch wood*

    The last time I had it out, drove for about 1hr+, and the machine only started complaining after a few stops in the water to wait for others to catch up.

    When I saw the notice, I shut her down, popped off the seat and felt the engine and exhaust pipes...the engine felt a little warm (you could eat it if it was dinner), and the exhaust pipes were a bit hotter compared to my friends Tigershark 1000.

    After I fired it back up, started driving at a reasonable speed, it took a few minutes and the over heating indicators went away, suggesting that higher speed driving was cooling it down.

    Any idea where to start looking?

    thanks

    I'd say either you have a partial cooling system plug, or the thermostat is starting to fail.

    You got that Genesis running?

    The MFI display said "HOT", or "Check Engine"?

    The heat sensor may have been cooked by the previous exhaust/engine overheating. I would replace the sensor.

    What did it take to get it running?
    Did you update your old thread?
