Buying Guide: Key Considerations For Livewell Bilge Pumps
- Flow rate vs. tank size: Match GPH to your livewell volume. Larger livewells benefit from 750–800 GPH pumps; smaller tanks can use 600 GPH without overworking the motor.
- Voltage and wiring: All pumps listed are 12V DC. Check your boat’s electrical capacity and plan for appropriate wiring gauges and fusing.
- Head height: Ensure the pump’s max head fits the vertical distance water must travel. Higher heads require higher flow pumps to maintain performance.
- Durability and environment: Saltwater use demands corrosion-resistant housings and components. Look for stainless steel shafts or corrosion-resistant plastics.
- Maintenance: Replaceable cartridges simplify service. Ant-Airlock features help maintain consistent flow in livewells with variable water conditions.
- Installation considerations: Submersible pumps save space and simplify mounting. Consider automatic switches for hands-off operation in bilge roles.
- Warranty and support: Four-year warranties are common with SEAFLO models, offering long-term security for boaters.
