    Engine Maintenance Display on RXP after Intake Clogged with Rag

    Well - not a good start to the day! The ski is a '04 RXP. After changing a wear ring we got what appears to be a rag stuck in the pump. It ran for a while (I assume spinning the rag on the prop), however, it eventually overheated due to low pump pressure. The overheat warning came on, it went off, and then the check engine light came on. The engine was hot when the hull was opened. There was a "puff" of steam from the engine compartment when the hull was opened (hot). We are wondering if the coolant reservoir overflowed, but not sure. Kind of wild considering that the ski was only running for about a minute before it was shut down. Got hot quick!

    We drug the ski home. Pulled the pump and removed a rag that was spun around the impeller. Put the pump back on the ski, took it back to the dock. The rag was pretty intact. Idle tested the ski - no problems at all. Actually, it runs better than it has for quite some time with the new wear ring. No problems with idle test. No check engine at idle speed. However, when the engine reaches 3,500 rpm the check engine warning and bell goes off. Runs fine, but we decided to quit and check with the forum before proceeding. It did not shred the rag, but we are going to check other cooling lines. There are no codes in the system to indicate why the check engine display comes up! Any ideas what to check next?

    Ok, did some more research on my '03 manual and found out to test when running. I received a fault code of P0544. This is a Exhaust gas Temperature Sensor Functional Problem. I am guessing at this point that she got hot enough to damage the sensor.

    Am I on the right track?

    You overheated exhaust, threw a code and put ski into limp mode....dealer will have to reset buds,also check that you didn't melt exhaust temp sensor(i did once )
