Meet the Attwood Tsunami Mk2 T500 12VDC 3 Amp Bilge Pump, a redesigned manual bilge solution engineered for reliability in freshwater boats. The standout feature is the patented X-Air™ Impeller, which actively ejects trapped air from the pump and pipework, preventing air locks and protecting the pump from burnout.

• Eliminates air locks: The only manual bilge pump designed to eliminate air locks, making it ultra-reliable in challenging conditions.
• Fast, simple installation: External mounting feet and an integrated outlet reduce installation time and effort.
