Common Concerns Answered
Is the Attwood Tsunami MK2 T1200 worth the investment compared to less expensive pumps?
While the initial cost may be higher, the unique Patented X-Air™ Impeller technology and enhanced freshwater protection offer significant long-term value by preventing common airlock failures and increasing durability in corrosive environments, directly mitigating potential repair costs and ensuring vessel safety.
Can I use any outlet fitting with this pump?
For optimal performance and to fully leverage the pump's engineered capabilities, it is recommended to use the specific Attwood Tsunami outlet designed for this series. While it is compatible with 1" and 1-1/8" hoses, using the proper outlet ensures efficient discharge and prevents potential flow restrictions.
How does the X-Air™ Impeller actually work to prevent airlocks?
The Patented X-Air™ Impeller is engineered with specific ports that actively eject any trapped air from the pump chamber during operation. This prevents the formation of air pockets that would otherwise disrupt water flow and cause the pump to run dry, a common issue in fluctuating water levels or when the pump is not fully submerged.
Frequently Asked Questions
What is the primary advantage of the Attwood Tsunami MK2 T1200's Patented X-Air™ Impeller?
The Patented X-Air™ Impeller is engineered to actively eject trapped air, preventing airlocks and ensuring consistent, reliable bilge water pumping, especially critical in freshwater applications.
How does the Tsunami MK2 improve upon the previous Mk1 model for freshwater use?
The Mk2 offers approximately 40% better protection against water ingress and electrolysis compared to the Mk1 model, specifically enhancing its durability and longevity in freshwater environments.
What is the maximum pumping capacity of the Attwood Tsunami MK2 T1200?
The pump is rated for a maximum flow rate of 1200 gallons per hour (GPH) when operating at its specified 12V DC voltage.
Can the discharge outlet be positioned easily for different hose routing scenarios?
Yes, the Tsunami MK2 features a 90° rotatable elbow outlet, allowing for 360° orientation of the discharge hose to facilitate easier installation in confined spaces and optimize routing.
Is this pump compatible with older Tsunami Mk1 components?
Yes, the Attwood Tsunami MK2 is backward compatible with the motor cartridges and hole mounting pattern of the previous Tsunami Mk1 series, simplifying upgrades for existing installations.
