SEAFLO 13E Series 1100 GPH Livewell Pump
Flow: 1100 GPH. Voltage: 12V. Head: 12 ft. Outlet: 1 inch or 1-1/8 inch. Motor: SFMA1-G1100-13A. Application: Marine livewell. Warranty: 4 years. Delivers strong 1100 GPH circulation, optimized for baitwell environments, with anti-airlock features and a cartridge motor for reliability.
Best for: Anglers needing high-flow circulation in larger livewells or bait tanks. Choose this if you require robust flow in challenging marine conditions. Caution: Some setups may require compatible fittings due to variable outlet sizes.
Buying Guide: Livewell Pumps For Pontoon Boats
- Flow rate vs. tank size: Match GPH to your livewell volume. Larger tanks benefit from 800–1100 GPH pumps, while smaller tanks can use 500 GPH models to avoid over-circulation.
- Head height: Consider the vertical lift from pump to outlet. Higher heads reduce effective flow; choose a pump with adequate head for your setup.
- Submersible vs. in-line: Submersible pumps simplify installation on pontoons but ensure proper sealing and clearance. In-line pumps require secure mounting and hoses with clamps.
- Anti-airlock technology: Look for anti-airlock features for consistent water exchange, especially in livewells where air pockets can disrupt flow.
- Durability: Corrosion-resistant housings and stainless steel components are beneficial in saltwater or mixed environments typical of close-drift pontoon use.
- Power and wiring: Most livewell pumps run on 12V DC. Check current draw to ensure your boat’s electrical system can handle peak needs without excessive battery drain.
- Hose compatibility: Verify outlet size (commonly 3/4″ or 1-1/8″) and ensure hoses and clamps are included or purchased together for a leak-free setup.
- Installation simplicity: Look for models with universal mounting bases or quick-connect fittings for ease of maintenance and cleaning on a pontoon.
Frequently Asked Questions
- What is a livewell pump best used for on a pontoon boat? – It circulates fresh water in bait tanks or livewells, keeping fish healthier and preventing stagnation.
- Should I choose a higher GPH pump for a small livewell? – Not always; oversizing can cause unnecessary turbulence. Match GPH to tank volume and need for rapid water exchange.
- Is anti-airlock protection important? – Yes, it helps maintain continuous flow and reduces the risk of stall in critical periods.
- Do pumps come with hoses and fittings? – Some do; check the product details and consider purchasing compatible hoses to complete the install.
- What maintenance is required for livewell pumps? – Regularly inspect for leaks, clean debris, and verify electrical connections and mounting stability.
- Can these pumps be used in freshwater and saltwater? – Most listed pumps are designed for both environments, but verify corrosion resistance for saltwater use.
