    Flush gone bad ... am I screwed??

    Newbie and first time poster. I've spent whole days reading this forum and think I came across this answer once, but spent an hour searching and couldn't come up with anything.

    I know I have to run the engine before turning on the water flow when flushing the cooling system. This is what happened.

    I hooked my ski up to a coin operated water dispenser. Turned on the ski, then paid the water dispenser and it started to flow. Everything is fine. I reved the engine once, waited a minute, then again, waited a minute, and then when I reved the third time the throttle got stuck open and the engine was reving very high (note - this never happened before and is a separate issue altoghether). I tried pumping the throttle a couple of times to see if it would unstick but that didn't work. I then followed my next instinct which was to kill the engine by pulling the laniard. So now the engine is off but water is still flowing (about 10 seconds). I freak out so I turn the engine back on (which in hind sight was NOT a good idea). The engine fired up but didn't really sound happy so I shut it back down after just a couple of seconds and removed the hose which was still flowing as quickly as possible but still took about another 30 seconds.

    So how bad did I f!$% up? My ski is at my dealer but I'm worried they don't have the experience to handle this issue.

    Please help.

    They need to find the throttle sticking problem first. Your motor should be fine if you didn't let it run more then a minute.

    The rough restart may be a throttle body issue. They can do a compression test on all 4 cylinders.

    Something ain't rite to get a throttle stuck open.

    Thanks Skip. I agree the throttle problem needs to be fixed. I was worried that water would have found its way into the engine.

    You would have had to let the hose run long enough to fill both waterboxes and even then its only a possibility. Only exposure to water is in the pipe from filling up and over the exhaust manifold to rest ontop of the exhaust valves.

    If your oil is not milky then you should be fine.

    This past weekend I was flushing my ski, Came across this. Throttle was stuck slightly. not WOT. But still was reving high. Not sure what caused it yet.

    did you turn the handle bars while hitting the throttle? if you did it may have something to do with the k.s.s

    Mine just kicked up on its own. Handlebars straight.

    The k.s.s. idea is very interesting, but I don't think I moved my handlebars either. Mine was not WOT either, but definitely reving in the 4-5k rpm.

    the very first time i rode my ski the throttle was sticking. It had something to do with the adjustable height or tilt steering. I could adjust the height and it would stick at a certain level. After it would stick i had to move the height to get it to idle down. Had to be a cable routing thing. Never has done it again.

    My ski was also revving high; I mean so high that I could not even pull the reverse lever while trying to back off the trailer. I paid no mind and did a U turn off the trailer. My ski idle at 7mph and thought there has to be something wrong.

    I remembered the last thing I did was adjust the throttle lever so it wouldn’t pinch my fingers at full throttle. It turns out I pushed it so far to the left that it was not fully closing on deceleration, it got caught on the rubber handle bar cover keeping it from closing fully.
