    my 94 polaris 750 will not start!

    hey guys, i am really desperate for some help. i rolled my jet ski over in the water a couple times this past weekend, now it will not start. I changed the plugs , that did not help. I crank it and when i pull the plugs out, they are wet. Any ideas? HELP!!!

    You need to start with the basics. Check compression, check for spark, and squirt some fuel mix in the carbs and see what happens.

    Welcome Ducati. Open the elec box and see if any water got into it, after you check for spark of course.

    Hi ducati, WELCOME to the Green hulk Forums!!

    Work quick, water is your cranks enemy. Do you still have or do you know if you have water inside the engine?

    Also check pulse line and fuel pump. You may have damaged the pump diaphrams.

    When you say plugs are wet, are you talking fuel or water?

    i think it has water in the engine?

    i t has spark because i can pull the plugs out and they will arc. but there is a foamy looking mix that will come out of the plug hole when i crank it without the plug in . HOW DO I GET THE WATER OUT ? DO I PULL THE ENGINE ?

    There are drain bolts under the exhaust down low one for each cylinder.

    Turn OFF the fuel or pinch the fuel supply line. Turn the craft on its side (read the decals for proper direction) and crank until you have no water exiting the cylinder. See if it starts then.
    How much water exited the cylinders when you originally cranked the engine after the roll overs?
    Was it running and just die?
    Did you have a rollover and then it wouldn't start? A little more info there please.
    Did the hull have a lot of water in it, after the roll overs?

    Ooooh, I like beers idea about removing the drain plugs, I never get the chance to do that because we're usually down the river when somebody fills a ski with water.

    there was quite a bit of water exiting the cylinders, it is mixed water fuel and oil.
    No it died when it was flipped the last time, i guess everytime it kept getting more and more water in the hull.yes it was really full of water . i will definetely try everyones ideas tonite
