Johnson Pump Aerator Head - 13-¾" Thru-Hull w/Off Vavle

The Johnson Pump Aerator Head with 13-¾" Thru-Hull and Off Valve is a marine ventilation and aerating spray assembly designed for live wells, bait wells, and freshwater/saltwater circulation systems aboard fishing vessels and recreational boats. This thru-hull aerator head integrates a dedicated shut-off valve, allowing operators to control water flow and aeration independently without compromising system integrity or requiring additional plumbing modifications.

Measuring 13-¾ inches in overall length, this thru-hull assembly is engineered for standard hull penetrations found on center consoles, bay boats, and offshore platforms. The integrated shut-off valve eliminates the need for separate ball valves or gate valves in the discharge line, reducing plumbing complexity and potential leak points. Johnson Pump's aerating head design produces a spray pattern that oxygenates water while minimizing turbulence, critical for keeping baitfish and tournament-caught fish alive during extended fishing days. The compact 0.3-pound assembly installs quickly and requires minimal maintenance when properly flushed after saltwater use.

This aerator head suits weekend anglers running small livewell systems, commercial fishing operations managing bait wells, and serious offshore competitors who depend on live fish retention. The off-valve feature is especially valuable in stop-and-go fishing scenarios where controlling aeration flow extends battery life on 12V or 24V livewell pump systems. Johnson Pump offers custom configuration options if your boat requires modified spray patterns, flow rates, or fitting sizes—contact the manufacturer with your vessel's specifications for tailored solutions beyond this standard thru-hull model.
