    HELP!! My 13' RXP X 260 keep over heat. Sand cause problem??? HELP??

    Hai guys.

    Thanks to this forums. Anyway i found my rxp is keep over heat. To be honest i play it on the beach. And when i start the engine and start the engine, sand sucked into the jetski. And speed getting low and low. I called the mechanic and he replace the oil cooler. Now its still the same? Do you think we need to clean all the sands from the waterbox? Any advise would be much appreciated.


    Second question does anyone tried springs cycles inter cooler?

    Welcome to the GH
    you may need to flush out the manifold
    it could have a lot of sand in it restricting water flow
    It is probably only a exhaust overheat not the motor
    overheat exhaust can cause the ski to sink

    why would you replace the oil cooler.... there should never be any sand in the engine cooling system
    unless you have modified it

    Hai Thanks for your explanation.

    anyway my mechanics was think since they are over heat, he was accused from broken oil cooler, so he change the oil cooler.

    anyway can you give me idea which one is manifold in the machine. This time i will try to fix my self. is it easy to open the manifold? big thanks!

    On the pump is a large plastic hex screw (cap screw). The purpose of that screw is to filter out larger particles from getting into system. These holes can get clogged so I suggest you remove it to inspect it. Back-flushing may not help in this case.

    Also if all the above fails pull the pipe off where it bolts to manifold there are several little small holes there and if several get plugged it will overheat in a hurry I had this happen and took me awhile to figure out. it would overheat after 2-3 minutes of riding had small pieces of gravel plugging holes
