    New Day- New Problem

    I am one unhappy RXP owner! I am having some big time issues with my ski. Any help is appreciated.

    Problem 1- It keeps overheating. Yes I have checked my water flow, strainer, IC, IC flushed, fittings, and sensors. I have also drilled out my yellow spacer and removed my rear exhaust line to increase water flow. But it still overheats! I thought I had it beat as it was good for about a week, but now its happening again. Oh and no error codes to report.

    Problem 2- Today on a ride (which was my worst day ever) BDNJ and I went out and I kept over heating so we decided to return home. On the way home I overheated again and shut the ski down. Now I can't get it to start. The starter turns but it wont start. I checked for spark and compression which is fine. It just won't start.

    Problem 3- Due to the ski not starting Brendan towed me in. Upon returning in I began looking for problems and when I checked my oil it had water in it. I checked it before we left and it was fine. But after the tow the oil was millky. How could this happen?

    For those of you who dont know me I have a 05 rxp with riva stage 2 and have been battleing this issue for sometime.

    Help me please,
    Mike Idizzy

    When you tow these things you need to pinch off the water inlet line.
    If you don't it will fill with water. That is probably how it got into your oil.

    that is correct and if you don't have a hose pincher or another tool to pinch the exaust hose stay well bellow the maximum towing speed of 15mph. i have seen this happen well too many times when a ski will not start because a simple dead battery or spark plug and by the time you get towed home to the ramp you get a bigger issue like a fludded engine.
    MODERATORS SHOULD MAYBE PUT THIS UNDER HOW TO SECTION.

    Its not your engine that is overheating its your exhaust temp sensor reading hot.

    Since you have flushed everything out its probably just a bad exhaust temp sensor.

    Never tow without pinching off the line going from your pump to your intercooler.

    If it is a bad sensor then this will be munber three. Why do they keep breaking?
    As for towing, I did not pinch the line and I was well OVER 15mph. But how would water get in the engine? Is that not closed loop? I thought only the exhaust was open to water and even if that backed up into the engine would it not just be sitting on top of the piston, thus either hydrolocking the ski (which did not happen) or staying there so it would not show up in my oil? Am I wrong?

    Also any ideas on why the ski will not start?

    Change the sensor and see if it starts.

    Water is pushed thru the piston rings and into the base when towing like you did.

    I removed the water/oil and replaced with new oil. Will I be OK? I will change the sensor today.

    You may need to boil out the engine. In most cases the oil will not become clean with one oil change.
