The new eco-friendly Rule Mate series of bilge pumps feature a solid state water sensing technology that eliminates the need for separate float switch. All-in-one pump & switch - No float switch required. Pump turns on when water level rises & shuts off when water is removed. Will not pump oil. Straight motor oil will not turn the pump on. Snap-off strainer for easy cleaning. Anti-fouling impeller. Limited three year warranty.

The Rule-Mate 500 and 750 automated bilge pumps offer many design features including a non-mercury float switch in a single compact housing while keeping size and cost to a minimum. When the float rises, the pump turns on. There is no on/off cycling and therefore, no power use until the pump comes on. Especially popular on smaller crafts. Rule 500 pumps are unmatched in pumping power and longevity. 3/4" discharge outlet. 12 volt.

Is this the old style? Two prong fitting? I want to use my old bace that's already mounted.?
No, this is the new style.
