Attwood Tsunami Mk2 T500 Aerator Kit

The Attwood Tsunami Mk2 T500 Aerator Kit is purpose-built for anglers running fishing boats with built-in livewells that lack factory-installed thru-hull recirculation systems. After years on the water, any serious livewell operator knows that water quality directly affects fish survival and tournament compliance—stagnant livewells stress fish and compromise your catch. This sealed aerator pump delivers reliable oxygen circulation, keeping baitfish and tournament-caught species alive and healthy during long days on the water, whether you're working shallow coastal flats or deep offshore grounds.

The Tsunami Mk2 T500 features a sealed pump design rated for occasional submersion, ensuring durability in the harsh marine environment where salt spray, moisture, and constant vibration take their toll on equipment. The motor draws minimal amperage, reducing drain on your boat's electrical system—critical when running other electronics. The compact 7 x 5 x 9 inch footprint and lightweight 1.15 lbs construction make installation straightforward in tight livewell spaces. Critically, the electrical connections must remain dry; proper wire routing and splash protection are non-negotiable during installation to ensure long-term reliability and safety.

This kit works best for anglers targeting species sensitive to water quality degradation—stripers, walleye, catfish, and saltwater redfish and snapper all benefit from consistent aeration during transport. Tournament fishermen upgrading older boats or retrofitting non-aerated livewells will find the Tsunami Mk2 T500 offers the reliability and compact design demanded by competition-grade livewell systems. Installation requires basic electrical knowledge and access to your livewell's interior; most anglers can complete setup in an afternoon using standard marine wiring practices and wire management techniques to protect connections from spray and submersion.
