Got a bit of experience with two strokes and water, best thing is to wash it out, use wd-40 or any other water displacer on the electronics especially and then let it dry.
Particularly with salt or brackish water, it's best not to let it dry without a complete rinsing to get the salt out.
I'm normally in fresh water so don't have to worry about drying, just pull the starter cord a few times to flush the cylinders, dry the plugs and go.

That day I had a messed up leg so took pics instead of playing.
