Yes, but there will inevitably be salty moisture lingering between close fitting parts (ooer
) so it won't just be when the trailer is being dunked. The moisture may dry out, probably leaving salt deposits, which will rehydrate (think that's the word!) if it gets fresh water on again. What happens to brakes when you dunk the back of a vehicle in salt water when launching is a good example.
