    Kaw. 15f Runs Hot

    Not sure if I am posting this in the right spot. I am working on an 06 15f. Ski has 128 hours. Runs fine sitting on the trailer with the grden hose attached. When you put it in the water it will run for about 2 to 3 minutes and then the stream coming off the side of the hull stops spitting water, steam comes out and the overheat warning comes on the display. No trouble codes. All cooling lines are in good shape. Not sure what else to look for. Any help would be appreciated.

    Fitting in the water box I's probably clogged. If you have checked all other lines and the screen on the pump. Then that's the probable cause. Check everything over real good and pull fitting out of side of water.box and check to see if it's clogged.

    I'd check the oil cooler water fitting....they are a known corrosion point, blocking water flow.

    I'm not sure that the 06 had this problem....I think they switched to brass at some point after a history of failed steel(coated) fittings

    That sounds strange.
    If warning light comes on the dash, that means heat sensors (oil temp/exh water termp) automatically send error signal to ECU.
    Have you hooked up the KDS to the ECU and checked for any registered codes?

    If only Oil Temp sensor got triggered - clogging is somewhere in the engine.

    If only Exh Water Temp sensor got triggered - clogging somewher in the exhaust sytem.

    If both sensors got triggered - clogging is at the uppers stream/inlet.

    No, it doesn't block the water flow. The aluminum fitting at the oil cooler corrodes/deterioates away and the cooling water will burst out into the engine compartment, flooding it.
