    Exhaust overheat

    Hi guys I have a '16 PX 300 and yesterday I was running alright and suddenly I had Exhaust overheat, not was fail sensor because I touched the exhaust and it was really hot and rubber of down was smelling burned. In the house with garden hose it is going well and exhaust and intercooler pisher is like normal. When I was in the water with the problem I removed a small hose from exhaust manifold (the upper one) and running the engine the water was coming out so in that point it not was blocked. The resonator is ok so i think only have more temperature in the waterbox

    Somebody know what could be? the pump dont have anything and my pwc always is running in salt water but always is clean with fresh water the exhaust system

    thank yo so much

    You may have clogged the strainer in the jet pump

    there are quite a few discussions on exhaust overheats due to various blockages, but the pump strainer is the most likely, you can try to garden hose flushing, but most of the time the screen is packed with coarse sand that juist won't flush out, so mechanical cleaning is needed. good time to pull the the pump and grease the driveshaft splines anyway....

    before you start melting some really expensive bits...
