There's a couple of types; some with internal or external float switches, or you can get external solid state switches. Yours, I believe, comes on periodically and if there's nothing to pump, it shuts off after a few seconds.
I personally don't like the idea of that, as the current drain on a boat that's sitting is considerably higher than a pump with a switch. That's jst me, though.
On my smaller boat, the 500gph Rule that I had featured a removable base. I believe it was a sort of bayonet mount. You mount the base to whatever you're putting it on, and then snap the rest of the pump onto it.
I do agree with others, though; 500gph sounds pretty small for a boat as large as yours.
