Parts Desk Insights
Best Use Case: This cartridge is the go-to recommendation when a customer's T500 Mk2 pump housing is intact but the motor has failed or lost performance. The cartridge system is the key advantage of the Tsunami Mk2 line — the motor swaps out in minutes without disturbing the through-hull wiring or hose connections. Stock this alongside the pump itself for service-minded customers.
The matching complete pump is the Attwood Tsunami T500 Mk2 Cartridge Bilge Pump, 12V. For higher-capacity needs, see the Tsunami T800 Mk2 (12V) and its T1200 Mk2 Replacement Motor Cartridge. The Tsunami MK2 800 GPH Bilge Pump is another strong option for larger bilge volumes.
