I don't imagine it would have been so happy if it had been in salt
water. I'd be worried about the water getting the bearings and washing
the lubricant out.
Salt water is also electrically conductive, so you would lose power to
the water, even if it wasn't conductive enough to actually cause a short
circuit failure.
