Marine's Best Bilge Pump

Attwood, the marine industry's largest and most trusted manufacturer of boat accessories, is famous for their superior bilge and aerator pumps - and the 500 GPH Tsunami is no exception. It is durable and designed to last, too. The efficient design circulates water around the pump motor housing, helping to absorb the heat given off by the operating motor extending the life of the entire unit.

Attwood uses the most advanced material available, including the best quality bearings and state-of-the-art brushes, alloys and magnets. Their patented shaft seal centers directly on the motor shaft, preventing leaks caused by misalignment and the exclusive molded two-wire seal is permanently fused to the insulation to prevent a leak path.

Finally, the pump's wiring is caulked and tinned to eliminate wicking, prevent water damage and resist corrosion.

As with all of our products, EzAcDc engineering helps to make every part of your boat wiring project simple, smart, and safe. When connected to EzAcDc products, you are assured of industry standard circuit protection.
