Attwood Tsunami Mk2 T500 Aerator - 12V - 90-Degree Inlet

The Attwood Tsunami Mk2 T500 Aerator is a 12-volt marine aeration system engineered to keep bait and fish alive during extended fishing trips and live-well maintenance. This dual-inlet model features a 90-degree inlet configuration paired with flexible outlet options, enabling installation in confined spaces where standard aerators won't fit. Attwood's fish-friendly design prioritizes gentle water circulation that minimizes stress on live baitfish and reduces oxygen depletion in holding tanks.

The Mk2 platform incorporates full backward compatibility with previous Tsunami models, making this aerator an ideal retrofit for existing live-well systems. The 3-1/2-inch by 3/4-inch thru-hull design accommodates standard mounting hardware, while the flexible inlet and outlet configuration eliminates the need to purchase separate adapter kits. At 1.1 pounds and measuring 8 by 4 by 9 inches, the compact footprint fits easily in tight bilge spaces without consuming valuable deck real estate. The 12-volt electrical draw integrates seamlessly with standard marine charging systems.

This aerator serves weekend fishermen managing small live-wells and serious offshore anglers running larger bait systems. The 90-degree inlet option proves especially valuable on boats with unconventional hull designs or where a straight-through installation would create plumbing conflicts. Weekend bass and walleye anglers benefit from the simple retrofit capability, while charter captains and tournament competitors rely on the proven Attwood reputation for consistent performance in salt and fresh water environments.

The Tsunami Mk2 T500 represents the evolution of a marine standard—proven reliability combined with modern installation flexibility. Marine systems require components that handle corrosion and vibration without degradation, and Attwood's track record reflects decades of field-tested engineering in working boat applications rather than consumer-grade alternatives.
