I used that method (except I got a thread adapter and screwed the pump into the threaded drain) when I first got my S-12 because I didn't want to drill a hole in the bottom of my boat. It worked well for pumping water but it left the pump as a big obstacle for the bait and they didn't circle the tank well. It will work fine if you don't crowd the tank too much. In the end, I drilled the holes and mounted the pump through the hull with no problems.
