So the solenoid might be waterproof, but what about the contacts that are directly on the winch?My old Warn has been through countless muddy and watery bog holes, hose off after every trip and spray some CRC in the control box every now and again , no worries. Mine still works like a charm.Hydraulic winch = S$&T. Simple as that.
If they are submerged, I can't see things working well if you kick on that solenoid
