    '09RXT-X - overheating

    I put my ski in the water yesterday & it filled up with water. I never took it off the trailer or start the engine. All the water was coming out the exhaust. I checked all the hoses to make sure they were on tight & everything looked good. I noticed the temperature switch was melted off the waterbox, so I unscrewed the threads out of the waterbox. The 3 inch hose going from the waterbox to the resonator was tight, but right below the hose clamp the resonator melted. That is where the water was coming in at. Does anyone have a solution?

    Seems like prior to this it ran without water to cool those exhaust components. Plastic melts fast with no water. You must have some idea about a prior overheat alarm or something? The only solution is to pull and replace all damaged exhaust components. Then retest and check for proper water flow and exhaust cooling

    I'd pull every water line and blow compressed air through it. It's amazing what can become lodged in certain places. Blow compressed air through the exhaust manifold as well. When you pull the stock water box, make sure the aluminum isn't melted on the exhaust manifold.
    For the money, throw a riva box and thru hull system on it.
    Good luck!

    Disregard ......your pump setup is different than my 2010 TX. The resonator IS the same.

    Check the main water intake line from the pump, hose, clamp, pump screen, restrictor, etc.

    I had this also, due to main supply hose from pump to iBR split.

    Raise your iBR gate, inspect S shaped hose from pump to left side IBR wall. It may have popped off or split wide open.

    I know of 3 others that had this happen also!
    Good call JT! I going with the hose being split too
