High-Performance Live Well Aeration with a 90° Inlet
The Attwood Tsunami MK2 Cartridge Aerator Pump with 90° inlet is built for anglers who need reliable, consistent live well aeration in a compact, serviceable package. The 90° inlet configuration is designed for installations where plumbing runs along the hull or live well wall — letting you route hose horizontally before the pump rather than needing a straight drop-in from above.
The MK2 generation brings meaningful upgrades over the original Tsunami: the motor cartridge is now truly single-handed serviceable with an improved grip, so you can swap it out on the water without tools. The cartridge is also backwards-compatible with previous Tsunami models, which means if you’re upgrading from an older pump, your existing housing stays in place.
Rated IP68 for full waterproofing and built to ISO 8846 Marine ignition protection standards — the same spec required for use near fuel vapors.

Parts Desk Insights
Best use case: The 90° inlet is the right choice when your live well plumbing runs horizontally — for example, when the pump mounts on a side wall or the inlet hose comes in from the side rather than straight down. It eliminates the need for a separate 90° elbow fitting in the plumbing run, which reduces potential leak points and keeps the install cleaner. If your hose drops straight down into the pump from above, the straight-inlet version is the simpler fit. This model is also a strong upgrade path for anyone running an older Tsunami aerator pump — the cartridge swaps directly into the existing housing.
