Attwood Tsunami Mk2 T500 Aerator - 12V - 3/4" NPT Inlet

The Attwood Tsunami Mk2 T500 Aerator - 12V - 3/4" NPT Inlet is a marine-grade air circulation system designed for bilge ventilation, live well aeration, and bait tank oxygenation on recreational and commercial vessels. Built by Attwood Marine, a trusted name in marine plumbing and ventilation solutions, this aerator delivers quiet, reliable performance in demanding saltwater and freshwater environments where water quality and equipment longevity directly impact operational success and safety.

This 12-volt aerator operates on standard marine electrical systems found on most boats, drawing minimal current while maximizing airflow efficiency. The 3/4" NPT (National Pipe Thread) inlet connects seamlessly to existing plumbing manifolds, fittings, and hose systems without adapter requirements. The Mk2 T500 design incorporates corrosion-resistant construction suitable for saltwater exposure, coupled with a sealed motor housing that prevents water intrusion and extends component life. Its compact footprint—measuring just 5 x 4 x 8 inches—allows flexible installation in engine rooms, under-deck spaces, or cabin areas where space is restricted, while the lightweight 0.8-pound design minimizes structural load on mounting brackets.

Boaters managing live wells, bait systems, and ballast tanks benefit most from this aerator's consistent output and low maintenance profile. Installation requires only a 12V power source (typically wired to the boat's auxiliary battery or switched panel) and standard hose barbs or NPT-threaded plumbing connections. The Tsunami Mk2 T500 is compatible with fresh and saltwater applications, making it ideal for bass boats, center consoles, commercial fishing vessels, and offshore platforms where reliable aeration prevents fish mortality, maintains bait vigor, and supports environmental compliance during long operational periods.
