Rule 46DR Replacement Motor — 800 GPH
Features: This 12V, water-cooled motor uses a stainless steel shaft and durable materials for long life in demanding marine conditions. The snap-in cartridge design makes maintenance quick, helping anglers minimize downtime. It delivers robust 800 GPH flow to keep bait and livewell water refreshed during a day on the water.
Best for: Boat owners upgrading an existing livewell without replacing the entire pump. Its simple snap-in cartridge reduces servicing time, making it ideal for tournament days or weekend trips where downtime matters.
Limitations: As a replacement motor, it assumes an existing compatible livewell unit. Ensure mounting compatibility with your current pump body and head assembly before purchase.
Yaegoo Livewell Pump — 800GPH
Features: A compact, rustproof 12V submersible with a stainless steel shaft and long life motor. It includes anti-airlock fins for even water flow and comes with two outlet configurations (straight and 90°), making it adaptable to tight spaces and various tank layouts.
Best for: Anglers with small to mid-sized livewells who need reliable performance in confined installations. The dual outlet options simplify fitting into boats with limited space.
Limitations: The shorter wiring and compact profile may limit maximum placement flexibility in very large livewells or high-volume boat setups.
SEAFLO 04 Series — 800 GPH
Features: 12V DC, 800 GPH, with a replaceable cartridge and a 4-year warranty. This unit is designed to deliver strong water circulation while remaining efficient on power. It has a durable housing resistant to corrosion for both salt and freshwater use.
Best for: Anglers seeking a balance of high flow and long-term reliability, suitable for regular use in varying marine conditions. The four-year warranty adds long-term peace of mind.
Limitations: Slightly larger footprint compared to ultracompact models; verify fit in very tight livewells before purchase.
SEAFLO 04 Series 800 GPH — Straight Intake
Features: Similar to the 600/800 GPH lineup, this variant includes straight intake with a 3/4″ NPT outlet and a replaceable cartridge. It’s designed for flexible routing around hulls and transoms with a four-year warranty for long-term reliability.
Best for: Boats with straightforward plumbing routes where a straight intake and simple installation are preferred. Great for replacing older, less efficient pumps with minimal plumbing changes.
Limitations: May be overpowered for very small livewells; ensure the 800 GPH rate suits your tank size to avoid turbulence or bait injury.
Retisee 12V 800GPH Kit
Features: This kit includes one 12V 800GPH livewell pump plus four stainless steel mesh strainers. The cartridge is easy to remove for cleaning, and the pump uses tin-coated 18-gauge wiring for safety. It provides dual outlet configurations (straight and 90°) and a compact, submersible design.
Best for: Anglers who want a complete kit with strainers for quicker setup and straightforward maintenance, particularly useful for backup systems or new livewells.
Limitations: The included strainers are helpful but ensure compatibility with your exact livewell inlet size and mounting layout.
Attwood Tsunami Mk2 — T800 (12V)
Features: 800 GPH, through-hull straight with fittings (elbow and straight), designed to keep bait and catch alive. Includes both 90° and straight outlets for flexible installation and faster service with no extra sealant or tools required.
Best for: Boaters needing a robust, widely compatible option with easy replacement and flexible routing, suitable for mid-sized livewells.
Limitations: Through-hull installations require careful sealing and compatibility with hull material; ensure you have the correct fittings for your vessel.
Attwood Tsunami Mk2 — T500 (12V)
Features: 500 GPH through-hull straight with fittings, dual outlet versatility, and straightforward service. Designed for dependable aeration and freshness in smaller livewells or when space is at a premium.
Best for: Smaller boats or livewells where a compact, easy-to-install pump is preferred. Good for lighter-duty use or when installing multiple livewells on a craft.
Limitations: Lower flow than 800 GPH models; may not keep larger livewells and high-bioload ecosystems adequately oxygenated during hot summer trips.
Amarine Made — 800GPH
Features: 800 GPH, submersible design, tin-coated 18-gauge wiring for safety. It offers a compact footprint with a 90° intake option and dual outlet configurations (straight and 90°). The stainless steel shaft adds durability for both fresh and saltwater environments.
Best for: Anglers needing a durable, space-efficient pump that can handle mixed water conditions and provide reliable circulation in mid-sized livewells.
Limitations: Ensure your mounting area can accommodate the pump’s dimensions; verify inlet and outlet spacing alignment to your hoses.
Buying Guide: Key Considerations For Choosing A Livewell Pump
- Livewell size and boat type: Larger livewells demand higher flow rates; smaller boats benefit from compact pumps with flexible outlet configurations.
- Flow rate vs. power draw: Higher GPH improves water turnover but uses more current. Match flow to your bait and catch needs to avoid stressing the ecosystem.
- Installation fit: Check intake/outlet fittings (straight vs 90°), through-hull or submersible design, and mounting dimensions for your hull and tank.
- Durability and materials: Stainless steel shafts, corrosion-resistant housings, and tin-coated wiring improve longevity in saltwater and harsh environments.
- Maintenance ease: Replaceable cartridges and easy-access strainers reduce downtime and simplify cleaning in field conditions.
- Warranty and support: A longer warranty often signals confidence in reliability; confirm installation support resources if needed.

- Is a replaceable cartridge easier to maintain? — Yes. Cartridges simplify cleaning and replacement, reducing downtime during trips or tournaments.
- Do I need a through-hull pump for my boat? — Through-hull pumps can save space and routing but require careful sealing and precise installation; consider your hull material and fittings.
- Can I install multiple pumps in one livewell system? — It’s possible, but plan plumbing and electrical load to avoid overflows or insufficient flow during peak use.
- What warranty is common on these 800 GPH pumps? — Many offer multi-year warranties (often around 4 years) indicating long-term reliability expectations.
