Expert opinion

« Technical analysis: ATTWOOD Tsunami T-500 Mk2 aerator pump »

The ATTWOOD Tsunami T-500 Mk2 aerator pump (reference 5640-4) is a suitable choice for fishing boats equipped with standard or medium-sized live wells. The Mk2 design brings significant improvements, particularly in ease of installation and maintenance—key criteria for professionals and demanding recreational boaters.

One of the main advantages of this model is its installation flexibility. With a straight inlet and a 3.5-inch (88 mm) through-mount length, it fits various hull or transom configurations. The required 1-1/8" hole diameter and 3/4" barbed outlet are key details for planning the installation.

In terms of maintenance, ATTWOOD has designed a cartridge-style motor with a "Twist-Out" feature that can be replaced single-handedly. This design drastically reduces the time and effort needed to inspect, clean, or replace the motor cartridge—an undeniable advantage for maintaining constant live-well oxygenation without immobilizing the boat. Additionally, Mk2 cartridge compatibility with previous Tsunami models ensures a smooth upgrade path for existing systems.

With a flow rate of 507 GPH (per ABYC specs at 13.6 V) or 1764 LPH (per ISO specs at 12.0 V) at 0 ft/m of discharge head, the Tsunami T-500 Mk2 is sized to provide excellent circulation and oxygenation in most small to medium-capacity live wells. For very large-volume live wells or more intensive water renewal requirements, consider higher-flow Mk2 models in the range, such as the 800 or 1200 GPH versions.
