📦 12V 1100GPH Automatic Submersible Bilge Pump – Marine Water Removal for Boats, RVs & Yachts

Keep your bilge dry and your boat safe with this fully automatic 1100 GPH submersible pump. Designed for 12V marine electrical systems, it moves up to 4,160 liters per hour—enough capacity to handle sudden rain downpours, stuffing box drips, and routine deck drainage without running your battery flat. The integrated float switch eliminates the need for an external controller: the pump cycles on automatically when water rises to a preset level and shuts off once the bilge is clear, so you don't have to monitor it manually. With a compact footprint and a discharge port diameter of 10 mm (inner) to 29 mm (outer), it fits snugly into tight bilge spaces on runabouts, fishing boats, pontoon boats, and small yachts. The durable thermoplastic body shrugs off saltwater, oil, and fuel residue, making it a year‑round workhorse for your onboard water management system. Whether you're replacing a failed original pump, upgrading a manual switch system, or adding redundancy to an offshore‑capable vessel, this bilge pump delivers the automatic reliability that peace of mind demands.
