Run the engine through a few revolutions, either by hand or with the starter motor, and that should pump clear the majority of the water from the cylinders.

How much water does it take to Hydrolock an engine?

If you have a 3.0 litre V6, the swept volume of each cylinder is 500ml. If you have a 10:1 compression ratio (close enough of a guess for a back-of-the-envelope calculation) then the total volume is 500ml/0.9 or 555.55 ml, so hydro-locking the engine would take about 56ml of water in a single cylinder.

Can a hydrolocked engine be fixed?
