Attwood Tsunami MK 2 Cartridge Aerator Pump – 90° Inlet | 56544

The Tsunami MK 2 is Attwood’s most refined livewell aerator pump — built for anglers who want reliable bait and fish survival without the hassle of complicated maintenance. The cartridge design lets you swap the motor with one hand, no tools required, and the updated grip makes it faster and easier than ever. IP68-rated for full submersion and ignition-protected to ISO 8846 Marine standards, it’s built to handle the marine environment and the safety requirements that come with it.

  • 90° inlet configuration — inlet draws water at a right angle to the pump body
  • Single-handed serviceable motor cartridge — no tools required
  • Backwards compatible with previous Tsunami pump cartridges
  • IP68 rated — fully submersible
  • Ignition protected: ISO 8846 Marine
  • Improved grip for faster, easier service

Parts Desk Insights

The 90° inlet is the right choice when your pump mount location doesn’t allow a straight inlet to point downward into the water — for example, when the pump is mounted on a side wall of the livewell rather than the floor or lid, or when plumbing constraints require the inlet to turn before entering the tank. The right-angle profile keeps the inlet submerged and drawing water even in awkward mounting positions where a straight inlet would be out of the water or blocked. If your installation allows a straight inlet, the Attwood 56634 Short Straight Inlet and Attwood 56604 Long Straight Inlet are available in this same MK 2 platform. For a lower-output 90° inlet option, see the Attwood 56504. For a recirculating aeration setup, the Attwood Tsunami Recirq Aerator Kit is worth considering.
