    Help - GP760 Dies with throttle in water

    I had the 99 GP760 out last weekend for a few hours and it ran great. This weekend, I dropped it in the water and it fired up and idoled but as soon as you accelerate it would die. It would fire back up, but die every time you accelerate. I took it out of the water it it fires up and can rev no problem. I did take the head off and replace the head gasket between last weekend and this weekend, but that is the only thing I did. All bolts are tightened to spec. I checked spark plugs and the little thing that screws on top of the spark plug came off inside the spark plug wire. Plugs were a bit black (rich), so I went ahead and replaced the plugs (BR8ES). Carbs were just rebuilt by OSB a couple months ago, so gas and spark should be good. Any thoughts? I will try to do compression test tonight.

    1) Possible Air leak?
    2) If battery is strong enough to start the ski, is should not affect keeping it running right?
    3) Fuel pump? Not getting enough gas to accelerate?
