Buying Guide
- Flow rate needs: Choose 1100 GPH for rapid drainage on larger jets or boats; 750–1000 GPH is common for smaller craft and moderate bilge loads.
- Automatic vs manual: Automatic with built-in float switches reduces manual monitoring; manual pumps require a separate switch or control system.
- Outflow fittings: Most pumps use 1-1/8″ or 3/4″ outlets. Confirm hose and fitting compatibility with your hull design.
- Durability: Look for corrosion-resistant housings and water-cooled or reinforced components for saltwater use.
- Installation kit: Some kits include hoses, clamps, and thru-hull fittings; consider these if you’re wiring a new system.
- Power draw: Check current draw to ensure your battery and wiring can support peak operation without overload.
- Maintenance: Anti-airlock features and sealed housings help reduce maintenance and prevent clogging.

- What does GPH mean for a bilge pump?
