Boat Bilge Pump 1100 GPH 12 V - High Performance & Reliable

From Sea-Harvester, a name mariners trust for durable, dependable marine hardware, the Boat Bilge Pump 1100 GPH 12 V is built to keep your bilge dry under real-world conditions. This compact, fully submersible pump tackles everyday spills and sudden deluges with ease, so you can stay focused on the voyage ahead.

Power and efficiency you can rely on: a 12 V DC motor delivers up to 1100 gallons per hour while drawing a safe 3.0 A under load. For steady operation, pair it with a 5 A fuse on a dedicated circuit. The pump runs quietly and with minimal maintenance, making it a practical addition to any boat’s bilge system.

Durable, corrosion‑resistant construction: a stainless steel shaft resists saltwater and splash, and the unit is fully submersible to handle wet bilges and rough seas. It uses marine-grade materials and complies with RoHS, SGS, and ISO standards for safety and environmental responsibility.

Flexible control for any setup: choose automatic operation with a compatible float switch for hands‑free bilge management, or use a standard on/off switch for manual pumping. The 1-1/8" discharge connects to common marine hoses, and the pump can push water up to 12 feet (4 meters) of head, accommodating a wide range of vessel configurations.

Easy installation and maintenance: a compact design with a 3' (1 m) power lead simplifies routing and connections in the bilge. The pump delivers dependable performance in both freshwater and saltwater environments, making it a versatile choice for small to mid-sized boats, runabouts, fishing boats, and pontoons.

Why it stands out

This model blends choice of control modes, a durable stainless shaft, and a generous 1100 GPH capacity, delivering rapid dewatering without excessive run time. It’s well suited for rain spouts, bilge wash‑downs, or maintenance where quick water removal matters, with reliable operation season after season even in challenging marine conditions.

Practical setup tips

• Ensure the 1-1/8" discharge matches your hose fittings for a secure, leak‑free connection.
• Position the pump for optimal intake flow and easy access to the 3' power lead.
• If using automatic mode, pair with a float switch and route wiring away from bilge debris to avoid false triggers.
• Use a 5 A fuse in the circuit for reliable protection—don’t exceed the pump’s load rating.
• Regularly inspect for debris and clean the intake screen to maintain maximum flow.
