Attwood Tsunami MK2 Aerator Pump Kit

Attwood Tsunami MK2 Aerator Pump Kit is a high-performance solution designed to keep live bait healthy and active by ensuring continuous water circulation and oxygenation in bait tanks and livewell systems. With its patented X-Air™ impeller technology, the pump actively prevents air locks and reduces the risk of dry running, improving reliability and extending service life. By maintaining cooler, well-oxygenated water, the system helps preserve baitfish vitality during long fishing trips, tournaments, and warm conditions where oxygen levels typically drop. Patented X-Air™ technology prevents air locks Unlike conventional bilge-style pumps, the Tsunami MK2 uses an advanced impeller design that automatically clears trapped air from the system. This ensures consistent water flow and eliminates one of the most common causes of pump failure in livewell setups. The result is smoother operation, fewer interruptions, and significantly reduced wear on the pump over time. Improved oxygen levels and water quality The system continuously circulates water through a dedicated aeration nozzle, increasing oxygen content while helping stabilize water temperature inside the bait tank. This creates a healthier environment for baitfish, reducing stress and improving survival rates—especially during extended periods on the water or when the boat is underway. Easy installation for new and existing systems The Tsunami MK2 can be integrated into existing livewell setups or used as a standalone aeration pump. Its compact design and included installation kit make setup straightforward, even in tight spaces commonly found in marine compartments. All essential components are included for a complete installation right out of the box.
