Marine Bilge Pumps & Automatic Dewatering Systems for Boats

Marine bilge pumps are one of the most critical safety components on any vessel, responsible for removing unwanted water from the bilge and preventing flooding. This category features a complete range of automatic, manual, submersible, high‑capacity, and multi‑pump bilge systems from trusted brands such as Whale Marine, Johnson Pump, Commodore, BILGE‑B‑DRY, and Attwood.

Choose from compact 500–800 GPH pumps for small boats, powerful 1100–2000 GPH units for larger vessels, and advanced automatic pumps with built‑in sensors for hands‑free operation. Multi‑pump systems from BILGE‑B‑DRY offer exceptional redundancy and rapid dewatering performance, while Commodore’s AMP Sensor and 60‑Series pumps provide reliable automatic activation without external switches.

Supporting components—including float switches, dry bilge systems, sump kits, and high‑flow electric pumps—ensure you can build a complete, dependable bilge management system tailored to your vessel’s size and safety requirements. Every pump is engineered for corrosion resistance, efficient water movement, and long‑term reliability in harsh marine environments.

Whether you’re upgrading an existing bilge system or outfitting a new vessel, these pumps deliver the performance and peace of mind every boater needs.
