Johnson Pump Aqua O2 Cartridge Aerator Pump – 1250 GPH, 90° Inlet

A high-output single-port livewell aerator pump delivering 1250 GPH — built for large livewells and serious bait-keeping applications where lower-output pumps fall short. The Aqua O2’s compact cartridge design fits in tighter spaces than traditional livewell pumps, and the motor cartridge swaps out easily when it’s time for service or replacement, without removing the entire pump housing. The 90° inlet configuration routes the intake at a right angle to the pump body, making it the right fit for side-wall mounts or installations where a straight inlet won’t clear.

  • 1250 GPH output — high-capacity single-port livewell pump
  • 90° inlet configuration
  • Two intake configurations supported
  • Compact profile — fits confined livewell spaces
  • Easy-change motor cartridge — no full pump removal required for service
  • 2-year warranty

Parts Desk Insights

At 1250 GPH, this pump is the right choice for large built-in livewells on centre consoles, bay boats, and offshore boats where you’re keeping a significant volume of water moving to support a full load of live bait or catch. It’s noticeably more powerful than the 500–800 GPH range and is worth the step-up when livewell volume exceeds roughly 20–30 gallons or when water temperature management is critical. The 90° inlet suits side-wall mount positions where a straight inlet would be out of the water or blocked. If you need a lower-output option in the same Aqua O2 cartridge platform, the Johnson Pump Aqua O2 Twinport 500 GPH and 800 GPH models are available. For a self-contained in-well aeration kit, see the Johnson Pump 34024 In-Well Aerator Kit. To protect the intake from debris, add the Johnson Pump 77125 Thru-Hull Intake Filter.
