Johnson Pump Aqua Jet Baitwell Pump – 5.2 GPM, 5-Chamber Diaphragm, 12V
A continuous-duty diaphragm pump purpose-built for baitwell and livewell applications that demand reliable, quiet, steady water flow. The 5-chamber diaphragm design delivers dramatically lower noise and water pulsation than 3 or 4-chamber pumps — important when you’re running the pump for hours at a time and don’t want the constant thrum of a pulsating pump in the cockpit. At 5.2 GPM (312 GPH), it moves enough water to keep a large baitwell fully refreshed continuously. Self-primes to 8.2’, includes an integrated pressure switch, and can run dry without damage — so a momentary loss of prime won’t burn out the pump. Includes an inlet strainer.

Parts Desk Insights
The Aqua Jet is the right pump when you need a dedicated flow-through water supply for a baitwell — continuously drawing fresh water from outside the hull and pumping it through the tank. The 5-chamber diaphragm design makes it noticeably quieter than most livewell pumps at this output level, which matters on a long day of fishing. The dry-run protection and integrated pressure switch mean you can wire it to a timer or switch without worrying about damage if the intake runs dry briefly. This is a flow-through pump, not an aerator — it replaces the water in the tank rather than recirculating it. If you need to supplement a flow-through system with recirculation while running at speed (when a thru-hull intake can’t draw water reliably), the Attwood Tsunami Recirq Aerator Kit is a good complement. To protect the intake from debris, the Johnson Pump 77125 Thru-Hull Intake Filter is a direct fit. For cartridge-style aerator pumps in the same Johnson Pump family, see the Johnson Pump Aqua O2 Aerator Pump range.
