Questions & Answers
Is this a genuine original part?
This is a genuine Attwood Tsunami Series pump, manufactured to the highest marine standards. 4boats.co.uk provides these as authorized replacements.
Will this replace my older Tsunami 500 pump?
Yes. The Mk2 motor cartridges are backward compatible with older Tsunami Mk1 housings, making upgrades quick and easy without re-plumbing your boat.
How do I clear an airlock in this pump?
The T500 (specifically the Mk2 version) features the X-Air™ Impeller, which is designed to automatically clear air bubbles from the pump and discharge line, eliminating the common "air-lock" failure found in standard pumps.
Note: Please verify your original part number and hose diameter (3/4") before purchasing to ensure fitment. This is a manual pump and requires a separate float switch or manual helm switch for operation.
