Put di electric grease inside both ends of the plug wires. Buy a can of wire drier (stp) from vatozone, shake it up and douse anything that looks like it may need it liberally. Let it dry and hit it again. Maybe two or three coats should do it. Pay attention to all the connectors if you're injected. Find a way to turn the fan off while in the water. I can blast into water an easy 50 mph and never skip a beat........
