Attwood Tsunami Mk2 T500 Aerator - 12V - Straight Inlet

The Attwood Tsunami Mk2 T500 Aerator with 12V straight inlet is a fish-keeping system designed to maintain bait and fish vitality during extended boating trips and fishing outings. Built on Attwood Marine's proven aeration technology, this unit combines proven fish-friendly operation with updated installation flexibility that addresses common deployment challenges found in earlier Tsunami models.

The Mk2 T500 features a 3.5-inch by 0.75-inch thru-hull opening, accommodating standard baitwell installations on center console, express, and offshore fishing vessels. The straight inlet configuration works alongside optional 90-degree adaptors, giving anglers flexibility in routing intake and discharge lines to match existing hull geometry and internal baitwell layouts. The 12V power specification aligns with standard marine electrical systems, drawing modest current suitable for dedicated circuits or secondary battery banks on fishing-focused vessels. Backward compatibility with previous Tsunami components simplifies retrofits and repairs on vessels already running older aeration systems.

This unit addresses the needs of saltwater and freshwater anglers who rely on live baitfish or hold catches for extended periods. Weekend fishermen keeping mackerel or mullet alive during all-day trips benefit from stable oxygen levels, while tournament competitors and commercial operations depend on consistent aeration to maintain fish quality and survival rates. The Tsunami Mk2 T500 serves center console boats, bay boats, and cruising vessels where space constraints and installation logistics demand proven, service-friendly equipment rather than experimental designs.

Attwood Marine's reputation in the marine accessories market reflects decades of experience serving the recreational and professional boating sectors. The Tsunami line remains a recognized choice among anglers seeking predictable aeration performance without over-engineered complexity. The Mk2 generation represents an evolution focused on practical installation improvements and long-term serviceability rather than fundamental redesign.
