SEAFLO 04 Series 800 GPH Livewell Aerator Pump
The SEAFLO 04 Series 800 GPH pump provides strong oxygenated water circulation with a 800 GPH output and a 4-year warranty. This model uses a replaceable cartridge motor and offers a ¾” NPT outlet for common livewell fittings. Best for anglers with mid- to large-size livewells who need reliable, long-term operation in both salt and freshwater.
Best for: boaters needing high flow with durable long-term reliability. Not ideal for ultra-compact spaces due to its dimensions, but the robust 13 ft max head suits deeper tanks.
Limitation: higher current draw (about 4.0A) may impact battery life on extended trips if not paired with a suitable power setup.
Yaegoo 12V 800GPH Livewell Pump
Yaegoo’s 800 GPH livewell pump emphasizes compact design with internal anti-airlock fins for even water flow. It’s suitable for anglers needing a smaller footprint while maintaining solid flow, and it includes two outlet configurations for flexibility. The motor is designed to resist rust and corrosion in fresh or salt water, making it a versatile choice for varied environments.
Best for: boats with tight livewell spaces or those seeking easier maintenance via a removable cartridge system. Choose this if you want flexible outlet options and corrosion resistance.
Limitation: might run hotter under back-to-back heavy use, so ensure adequate cooling and battery management on long trips.
Attwood Tsunami MK2 T500 Aerator Pump
The Attwood Tsunami MK2 T500 offers 500 GPH with a through-hull straight setup and two fittings (elbow and straight). It’s designed for reliable bait and catch aeration and supports quick, tool-free service. The dual outlet options enable rapid adaptation to different livewell configurations, making it a practical choice for flexible installations.
Best for: anglers who want a proven, easy-to-install option with flexible outlet configurations. Better for smaller livewells or spaces where a larger pump isn’t needed.
Limitation: lower flow compared with 800 GPH models, which may be less ideal for very large livewells or aggressive aeration needs.
Amarine Made 12V 800GPH Livewell Pump
Amarine Made delivers an 800 GPH livewell pump with anti-airlock fins and a corrosion-resistant motor housing. The design emphasizes a compact profile for tighter installations and a 90° threaded intake for versatile mounting.

This SEAFLO portable kit features an 800 GPH flow rate, a submersible design, and a self-contained system with a spray head for aeration. It’s optimized for use as a backup pump or for temporary, portable livewells in boats, camps, or fishing ventures. The 4-year warranty signals long-term durability for mobile setups.
Best for: boaters needing a portable, self-contained aeration solution or a reliable backup pump. Choose this for versatility and ease of transport.
Limitation: as a portable unit, it may require more frequent setup and teardown compared with permanently installed pumps.
Buying Guide
- Flow rate vs. tank size: Larger livewells benefit from 800 GPH units; smaller tanks can use 500–600 GPH without over-aerating.
- Power and electrical load: Ensure your battery capacity and wiring can support pumps drawing 4.0 A or more, especially on long trips.
- Installation type: Submersible, through-hull, and portable kits suit different boat layouts. Consider outlet configurations (straight vs. 90°) for flexible routing.
- Material and corrosion resistance: Saltwater environments demand stainless steel shafts, corrosion-resistant housings, and easy cleaning.
- Warranty and serviceability: A multi-year warranty plus replaceable cartridges can reduce maintenance costs and downtime.
- Maintenance considerations: Look for anti-airlock fins or simple cartridge systems to simplify cleaning and prevent airlocks.
- Space constraints: Compact profiles help fit in tight livewells or small boats without sacrificing flow.
FAQ
- What’s the recommended pump size for a 20–25 gallon livewell? A pump around 600–800 GPH is typically suitable for that range, depending on desired turnover rate and aeration needs.
- Can I run a livewell pump on a 12V marine battery? Yes. Ensure the battery capacity supports the pump’s current draw and that connections are water-safe.
- Is a portable livewell kit as effective as a built-in pump? Portable kits can be effective for backup use or temporary setups, but built-in pumps often offer more consistent performance and integration.
- Do I need both straight and 90° outlets? Having both provides installation flexibility to fit different livewell fittings and routing paths.
- How often should I clean a livewell pump? Clean every fishing season or sooner if you notice reduced flow or debris buildup.
- Are these pumps suitable for saltwater? Most listed models are designed for both fresh and saltwater use, but verify corrosion resistance and shaft material for your environment.
