    polaris msx 140 pipe leak pleas help

    hi My jet ski is taking on water when the engine is turned on. I have ran it through the (this was at the front end off the engine) hose and have found that the pipe had a crack in it where it was about to be inserted . I have cut it off and re attached it. Once again I have put the hose to it and it looks like there is another small leak somewhere that i cant find. I know roughly where it could be but cant find any pipes around there.

    If anyone has any diagram off where the pipes are would you please be able to upload them to me please.

    Also what happens if I leave the hose running with the engine turned off. Does anything get filled up ??

    Thank you

    Never run the hose with the ski not running,Water can fill the cylinders thru the exhaust ports. Always start ski...turn water on....turn water off ....then shut off ski.

    There is 2 fittings on the front side of the stator cooling cover near the fuel tank on the 140,they let water help keep the stator cooler. If you had one cracked hose up there,they both may need replacing. Or the gasket between the cooling cover and stator cover may be leaking.
    Cooling Cover #28, Gasket #33, Fittings hoses attach to #30
