    2000 polaris genesis.. cranks but wont start. carb engine

    hi guys

    I'm new to the forums as well as pwc's. I have a polaris genesis 1200 red 3cyl carb engine.

    I have a problem with my polaris. i had it in the water all morning and it was running fine until a buddy of mine rode it and sucked up seaweed in the jet and it choked, he didn't know and gave it gas. He flooded the engine i believe. After some cranking i managed to start the engine but it was running real rough and wouldn't go over like 20mph, and suddenly it just shut off. after that i tried cranking it and nothing.

    so i took it out of the water and brought it home. I took a look at it and it seems that i'm not getting any spark. I checked the wiring and it all seems to be intact.

    Is it he distributor or the coil pack? I have no clue about this as its my first polaris and have never worked on them before.

    any help is appreciated.

    thanks

    My guess is that the engine was overheated from repeatedly revving it without water flow. Check cylinder compression.

    No spark I suspect is caused by a weak battery.

    the compression is above 120 on all 3 cylinder. I am going to fully charge the battery and see if that helps, but in the mean time is there anything else i should do or check?

    thanks

    Runnng rough and then stopping suddenly, after prior sudden stopping while clogged with weeds?
    Hmm, sounds like a piston is hot seizing or possibly a crank bearing. Possibly the jet pump.

    I would remove the jet pump and check for binding in the pump bearings or debris stuck in the blades.

    removed jet pump-clean and no debris
    charged battery and was getting 13.0 voltage. cranked it and herd it jump once and that was it.
    checked plugs for fuel it was wet.

    also found out that when my buddy was riding it the bilge pump stopped working and the ski was half way full of water. he took it out and emptied the water out and than like 30 min later all this happened.

    any other opinions?

    thanks

    So the hull was flooded? Open the electric box and check for water/moisture

    The electrical box was wet and full of moisture. I took it apart and let it dry out. Is there anything that can be damaged by water? What should I do next?

    Thanks

    Hard to say, I had same problem once but everything works fine after e-box was dried out.

    Electrical box is completely dry now. Been sitting in the sun for the past two days.

    New battery with 13.1+ voltage

    Still nothing. No spark to the plugs.

    Ignition coil no good? Wires no good?

    Anything else I should be looking for?

    Thanks
