SEAFLO Auto Bilge Pump 750 GPH 12V – Built-in Float Switch
Leave the bilge to the pump. The SEAFLO 750 GPH automatic is an all-in-one unit — pump and float switch in one compact body — so you don’t buy, wire, or mount a second switch.
When water comes up, it starts. When the water is gone, it stops. That’s it. No panel flicking on a quiet night at the ramp, and no power draw until the float actually calls for it.
Rated at 750 gallons per hour (about 2,840 L/hr) through a 3/4" (19 mm) outlet, it is sized for tinnies, runabouts, and mid-size hulls that need a proper auto pump without a bulky install. An anti-fouling impeller keeps flow up. The snap-off strainer pops off for a fast clean when the bilge gets messy.
Straight motor oil in the bilge will not turn this pump on, so you are not pumping a slick over the side. Fully submersible, marine-duty wiring, and a 2-year warranty.
No extra float switch required. Wire it up, sit it in the lowest point of the bilge, and it looks after itself.

Buyer note
Automatic operation uses the brown/white + black wires. For water only — not oil, fuel. Use a correctly rated fuse.
