    Water in cylinders ??? Wasn't there before hooking up hose

    I tried to start my sisters GP 1200 and it would not start. I pulled the plugs and cleaned them. Hooked up the hose to the place under the seat and tried again. It still would not start. Now when I pull the plugs there is water on them. I disconnected the hose and cranked it with all three plugs out. Water spit out of each cylinder as it cranked.

    Is it probably a cracked engine? How can I get the water out to prevent damage?

    Any place with instructions for fixing/replacing engine?

    Thanks,

    dale

    you say that you hooked up hose? I'm hoping you cranked ski before turning water on and turned off water before turning off ski?

    Keep turning motor over with plugs out until all water quits shooting. then put a little gas in, plugs back in and crank. If it cranks, take to water and run ski for awhile to make sure all water is gone and will not start rusting anything. You can't wait 1 or 2 days to do this.

    Maybe the water pressure was too high? You can flood the engines of some jet skis if you supply too much water even if you follow the right flush procedure.

    What if it has been 3 days already??? I did hook up the water while trying to start it. I do not know how much pressure was on. It did not start so I took the water off but it ran while the engine was off.

    I was so worried about the engine over heating. Much of the water came out when turning it over but it may not be dry yet.

    OOOOOPS!

    thanks for the info,

    When you flush you first start the engine and then immediatly supply water and let the engine for about five minutes. After the flush turn the water off and then rev the engine a few times(DO NOT OVER rev it though, just a little) to get the water out of the exhaust and then turn the engine off.

    I would like to just clear up what I should do.

    Flush the engine by cranking with spark plugs out/in?
    Let the engine pump water out as much as possible so cylinders will work?
    Start engine with water hooked up but turned off until engine is running?
    Let engine run for five minutes with water hooked up? How much water?
    Turn water off while engine is running and rev for a few seconds to get the water out before shutting off engine?

    Thanks,

    dale

    just remember this.......engine off = water off
    engine running = water running

    but right now you NEED TO GET THAT THING RUNNING !!!

    Don't wait for the fireworks or your favorite TV show.

    You should take the ski out and run it for at least 30 minutes, get it nice and hot to burn off all the moisture.
    If you don't than you will loose the crank.
