Your motor is likely hydro- locked on water.

Remove all the spark plugs and spin the engine over to get the water out of the cylinders. Don't be surprised if it has done serious internal damage. If the engine was running when this happened, it usually bends or breaks connecting rods. I've had to change many engines for that reason. NEVER drive through high water.
