Parts Desk Insights
Best Use Case: Recommend this cartridge when a customer's T800 Mk2 pump housing is in good shape but the motor has failed or lost output. The T800 is a popular mid-range bilge pump for mid-size powerboats and sailboats — having a spare cartridge aboard means a bilge pump failure can be resolved in minutes at the dock or on the water without tools beyond a screwdriver. This is a strong upsell alongside any new T800 Mk2 pump sale.
