Parts Desk Insights
Best Use Case: Ideal for boats that want reliable, automatic bilge pumping with the convenience of the prewired Ultima digital switch and cartridge-style serviceability.
Common Issues: If performance seems reduced, confirm the Dura-Port hose connections and check valve seating during installation/service. For troubleshooting cycling behavior, inspect the switch mounting and ensure the bilge area where sensing occurs is not obstructed, and verify correct power/12V wiring to the Ultima switch system.
