Twice the Output. Twice the Value.

Clever Multifunction Pump

The Attwood Tsunami Dual-Outlet Aerator Pump is more efficient and more useful than any competitive livewell pumps.

Some dual-port aerator pumps offer a second hole below the pressure chamber to get the “dual-port” name, while others simply glue a threaded housing to the bottom of an existing aerator pump. But, as you would expect from the world's top producer of boat parts, Attwood delivers much more. The Tsunami's second outlet is integrated into the pressure chamber, so it looks — and pumps — like part of the aerator.

Beneath the standard 3/4" barbed outlet, there's a second hose-threaded outlet on the pressure housing. Both outlets are engineered for the precise position and angle that will deliver optimum performance.

Output and Performance

The advantage of the dual outlet livewell pump is that you can feed multiple applications through a single thru-hull fitting, which can be straight thru-transom, remote or seacock-mounted. Whichever you choose, you can actually feed two livewells…or use the second outlet for a low pressure rinse hose. Or, use one outlet to aerate, and route the other outlet to a positive displacement pump, using it as an intake for a high-pressure washdown application.

Our Most Versatile Aerator

This Attwood aerator pump delivers all the engineering advances of the leader in livewell pump engineering:

• Water-cooled motor inside a tough housing made of engineered alloy resin.
• Housing resists impacts, UV, chemicals, and the plasticizers used in most hoses. Even resists the acetic acid used in silicone sealants
• Patented stainless steel reinforced motor shaft seal that ensures perfect alignment and sealing.

Marine's Best Livewell Pump

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

Attwood uses the most advanced material available, including the best quality bearings and state-of-the-art brushes, alloys and magnets - just what you'd expect from the industry's top manufacturer of boat parts. Their patented shaft seal centers directly on the aerator pump 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 Attwood livewell pump wiring is caulked and tinned to eliminate wicking, prevent water damage and resist corrosion.
