Keep Your Catch Alive Longer
The T-H Marine Pro Live Well Oxygenator (Flush Mount) is engineered to maintain a healthy, oxygen-rich environment in live wells from 10 to 20 gallons — even in the heat of summer when warm water holds the least dissolved oxygen. Unlike traditional aerators that simply agitate the surface, this unit actively produces 100% pure oxygen by electrolyzing water, splitting hydrogen from oxygen at the molecular level to create a super-saturated environment your bait and catch can thrive in.
The flush-mount design integrates cleanly into your boat's existing live well lid or deck, and the unit runs silently off your boat's 12V battery — no extra power source required.
- Produces 100% pure oxygen — not just aerated water
- Retrofits most live wells from 10 to 20 gallons
- Flush-mount design for a clean, integrated installation
- Silent 12V operation off your existing boat battery
- Super-saturates the water even in warm conditions
- 3-year manufacturer warranty
Parts Desk Insights
Best use case: This oxygenator is the right choice when you're fishing in warm-water conditions — summer bass tournaments, inshore fishing, or any situation where keeping live bait or a catch alive for extended periods is critical. It outperforms standard aerator pumps in high-temperature water where dissolved oxygen levels drop fastest. Ideal for anglers who want a permanent, low-profile installation rather than a portable unit.
Installation note: Designed for flush-mount applications — requires a cutout in the live well lid or deck panel. Runs directly off a 12V DC connection. No additional pump or plumbing required for oxygenation.
Pair it with: Complete your live well system with compatible T-H Marine accessories:
- T-H Marine Stainless Steel Wire Mesh Strainer — protects pump intakes from debris
- T-H Marine Aerator Filter Dome — pre-filters water entering the system
- T-H Marine Straight Aerator Head with Shut-Off Valve — for spray distribution control
- T-H Marine 90° Aerator Spray Head with Shut-Off Valve — angled spray for better coverage
