HI and thank you for your question.
I do have a couple of questions for you.
1.) Do you know if water got in the engine?
2.) If yes, what did you do to get it out of the engine?
3.) Was it salt water or fresh water that flooded the engine compartment?
There are a couple of ways.
The first would be pull the spark plugs out and crank the engine over and see if it sprays water out like a high pressure fountain.
If it isn't spraying water out, there could be a bit of water in it. A way to check that is to pull the spark plugs out and tap the threaded end on the palm of your hand and see if droplets of water come out of the tip on your palm.
If neither of those happen, you did not get water in the engine. If either happens, you need to get it running ASAP to mitigate the damage. Salt water is extremely corrosive and will cause internal damage due to corrosion.
