Attwood Tsunami Mk2 T800 Aerator - 12V - 90-Degree Inlet

The Attwood Tsunami Mk2 T800 Aerator in 12V with 90-degree inlet is a fish-keeping system engineered to maintain live bait and catch during extended time on the water. Attwood's Tsunami aerator line has earned recognition in the marine industry for fish-friendly circulation that minimizes stress while keeping water oxygenated—critical for anyone serious about live bait presentation and fish survival rates during tournaments or extended offshore trips.

The Mark 2 generation introduces installation flexibility that earlier Tsunami models lacked. The 90-degree inlet design accommodates various hull configurations and bilge layouts without requiring custom fabrication. The 3-1/2-inch by 3/4-inch thru-hull opening integrates cleanly into most center console and cabin cruiser designs. Operating on standard 12-volt marine power, the unit draws modest current while maintaining consistent water circulation—important for day-long operation without battery strain. Full backward compatibility with previous Tsunami components means existing Tsunami users can upgrade selectively without replacing entire systems.

This aerator suits weekend fishermen running small baitwell systems and serious anglers operating larger live-wells on offshore vessels. The compact footprint (8 x 4 x 9 inches) and 1.5-pound weight make installation straightforward without adding significant bulk to engine rooms or bilge spaces. Whether you're running mullet, shiners, or herring in saltwater or freshwater conditions, maintaining proper oxygen levels directly impacts bait viability and ultimately your success rate on the water.
