As a point of order: flooding an engine refers to having so much fuel in the cylinders that it cannot be ignited because there isn't enough air to support combustion. Filling the cylinders with water results in hydro locking an engine because the liquid cannot be compressed on the compression stroke. This can result in damaging the internal parts of the engine. Bent connecting rods are a common issue. If you've gotten in deep enough to get water in through the intake manifold, it's quite likely that a great many other things that shouldn't be gotten wet have (wiring, interior, etc.) and it's not just the engine that will need to be replaced.
