Possible new thruster source/idea

I found something interesting in eBay today and thought I'd share. In case you haven't come across them yet...brushless submersible circulating pumps. I wonder how these would work? No depth rating on them, but then again the bilge pumps weren't designed for more that a foot or so either

interesting.

I wonder if they are reversible.
