With innovative engineering and a compact design, Tsunami bilge pumps deliver high output from a small package. Durable and designed to last, these pumps feature cooler-running motors, watertight seals, and waterproof priming. The efficient design circulates water around the pump motor housing, helping to absorb the heat given off by the operating motor. Cartridges are replaceable, interchangeable, and easy to install. 3/4" Hose Size | T800 Tsunami Bilge Pump
