That shouldn't cause any problems either. The ESC should be fairly well protected in the fuselage, and freshwater condensation will not affect the motor. I'd dry everything out carefully after a wet...

You may need to reverse the throttle servo. ESC may be getting a full-throttle signal and won't arm. I'd recommend removing the prop until you have reliable throttle...
