Product Compatibility
Designed for 12V marine bilge systems requiring a compact automatic pump with approximately 750 GPH capacity and a 3/4" discharge hose connection. Best fit depends on available bilge space, hose size, wiring, fuse protection, and required pump capacity.
Fitment Notice
Confirm system voltage, existing hose diameter, mounting space, wiring condition, and required GPH capacity before ordering. Bilge pump output depends on discharge height, hose routing, voltage, and installation condition, so real-world flow may be lower than open-flow rating.
When This Part Needs Replacement
Replace the bilge pump if it no longer runs, activates inconsistently, fails to switch on automatically, has reduced flow, makes abnormal noise, has damaged wiring, or the strainer/pump housing is cracked or blocked beyond cleaning.
Installation Notes
Install low in the bilge where water collects, while keeping the pump accessible for inspection and cleaning. Use marine-grade wiring, proper fuse protection, correct polarity, and a discharge hose matched to the pump outlet. Route hose to avoid kinks, high loops that trap water, or backflow into the bilge. Test both automatic and manual operation after installation.

Parts Desk Insight
The biggest checks with this pump are 12V power, 3/4" hose size, and available bilge depth. Automatic pumps are convenient, but they still need clean strainers and routine testing so the switch does not get blocked by bilge debris.
