SEAFLO 12V 800 GPH 13F Livewell Aerator Kit

Best for: Anglers who need a portable, self-contained livewell system with reliable 800 GPH performance. This kit recirculates water to maintain oxygen and temperature, suitable for bait tanks or as a fail-safe backup pump in some setups. The system operates quietly and supports a 3/4” outlet. Caution: ensure compatible wiring and tank fittings for your boat’s configuration.
SEAFLO 04 Series 800 GPH Baitwell Pump

Best for: Frequent anglers who need strong 800 GPH water flow with long-term reliability. This pump features a replaceable cartridge motor and a long warranty, making it suited for regular use on longer trips. It supports saltwater and freshwater, with a ¾” NPT outlet. Caution: higher current draw (about 4.0A) means ensure your power system can handle it.
Retisee 12V 800GPH Livewell Kit

Best for: Boat owners with limited space who want easy maintenance and flexible outlet options. The kit includes multiple stainless steel strainers and a cartridge-style pump for easier cleaning. Internal fins promote even water flow in smaller wells. Caution: verify compatibility with your livewell’s outlet configurations before buying.
SEAFLO 09 Series 350 GPH Portable Livewell Kit

Best for: Smaller livewells or mobile setups where space and power are limited. The 350 GPH rate, adjustable spray head, and compact form provide flexible installation. Caution: lower flow may be insufficient for larger tanks or high-traffic bait wells.
Amarine Made 12V 800GPH Livewell Pump

Best for: Those seeking a robust 800 GPH option with easy maintenance and compatibility with various livewell configurations. The pump features a corrosion-resistant design and 90-degree intake. Caution: check if your transom and hoses can accommodate the included outlet options.
Buying Guide
What size livewell requires what flow rate?
Smaller livewells may operate well with 350–500 GPH pumps, while larger bait tanks or high-traffic setups benefit from 800 GPH or more. Higher flow preserves oxygen levels and prevents stagnation during longer trips.
Portable vs. built-in systems: which fits?
Portable kits are ideal for anglers who need flexibility or temporary installations. Built-in or cartridge-style systems are better for long-term use on boats with limited space and frequent in-water operation.
Power considerations: voltage and current draw
Most livewell pumps run on 12V DC. Higher flow rates generally draw more current, so ensure your battery, fuse ratings, and wiring can safely handle current draw without voltage drop.
Maintenance and warranties: how to choose
Look for replaceable cartridges, easy-access cleanliness, and long warranties. A four-year warranty often signals durable construction and vendor confidence in performance across marine environments.
Materials and corrosion resistance
Stainless steel shafts and corrosion-resistant housings help ensure longevity in saltwater use. If you operate in freshwater, corrosion resistance remains beneficial but less critical than in saltwater environments.
Ease of installation and compatibility
Check hose sizes, outlet thread types (¾” NPT vs. hose barb), and inlet orientations (straight vs. 90-degree) to ensure plug-and-play compatibility with your livewell and existing plumbing.
Frequently Asked Questions
- What is a livewell aerator pump used for? It circulates water to oxygenate and cool livebait and fish, helping keep them healthy during transport.
- Is 800 GPH necessary for all livewells? Not always; it depends on tank size and the number of live creatures. Larger setups generally benefit from higher flow.
- Can I use a 12V pump in saltwater? Yes, most 12V livewell pumps are designed for both fresh and saltwater; verify corrosion resistance.
- Do I need a through-hull connection? Some kits are self-contained and recirculating, while others require a through-hull or external fill system for continuous operation.
- How often should I clean the pump cartridge? Regular maintenance with easy-access cartridges helps prevent blockages and maintains flow.
- What is the difference between 350 GPH and 800 GPH? A higher GPH rate provides more rapid circulation and oxygenation, beneficial for larger or busier livewells.
