Attwood Tsunami Mk2 500 GPH (5606-7)

Next-Generation Anti-Airlock Bilge Pump

The Attwood Tsunami Mk2 is the most reliable manual bilge pump in its class, engineered to solve the most common cause of pump failure: air-locks. Featuring the patented X-Air™ Impeller, this pump actively ejects trapped air bubbles from the housing and pipework, ensuring the pump never runs dry or burns out prematurely.

RELIABILITY: Built with 40% better protection against water ingress and electrolysis compared to the original Mk1 series.

Key Features

  • ✔ Patented X-Air™ Impeller: Prevents air-locking.
  • ✔ One-Hand Release: Easy-to-service motor cartridge.
  • ✔ Flexible Installation: 90° rotatable elbow outlet.
  • ✔ Retrofit Ready: Matches Mk1 hole patterns.

Questions & Answers

Is this a genuine original part?

Yes, this is a genuine Attwood Tsunami Mk2 product. 4boats.co.uk supplies only authentic marine equipment to ensure safety and compliance.

How do I know if it is compatible?

We recommend checking the SKU/MPN 5606-7. If you are replacing an older Tsunami Mk1 (Series 4600), the mounting base will fit the same holes, making this a direct "plug and play" upgrade.

Does "Threaded Outlet" mean it fits standard NPT fittings?

The "Threaded Outlet" descriptor refers to the pump's discharge port, which features a 3/4" thread designed to accept the included Attwood barb fittings. This provides a more secure, leak-proof connection than simple friction-fit barbs.

Note: Please verify your original part number against the references above before purchasing. For any installation queries, refer to the Attwood Marine technical datasheet.

For the products under £150 the shipping is £6.99.
