Buying Guide: Key Purchase Considerations

  • Automatic sensing vs. manual: If you want hands-off operation, choose pumps with electronic sensing or built-in float switches. If you prefer manual control, some SEAFLO models offer both modes.
  • Flow rate vs. head pressure: 2000 GPH is a high-flow rate suitable for most mid-sized bilges. Check maximum head height (feet) to ensure it matches your boat’s bilge depth.
  • Outlet size compatibility: Most pumps use 1-1/8″ or 1″ outlets. Confirm your hose and fittings match the discharge size to prevent leaks.
  • Durability and materials: Look for corrosion-resistant housings and marine-grade wiring for longer service life in harsh marine environments.
  • Warranty and support: A longer warranty signals manufacturer confidence and can be valuable for ongoing maintenance and parts replacement.
  • Installation considerations: Some pumps require adapters, filters, or strainers. Consider access to the bilge, vibration, and mounting options.
