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.
