Johnson Pump 77125 Aerator Thru-Hull Intake Filter
A two-piece intake filter designed to keep debris out of your aerator thru-hull fitting and protect the pump from clogging. The mounting base installs directly under the aerator thru-hull nut — no drilling, no extra hardware. Once the nut is tightened, the filter body twists on and locks in place. When it needs cleaning, twist it off, rinse it out, and twist it back on. Simple, fast, and tool-free.
- Two-piece design: mounting base + twist-off filter body
- Installs under the aerator thru-hull nut — no additional hardware required
- Twist-off filter body for tool-free removal and cleaning
- Protects aerator pump from debris ingestion
Parts Desk Insights
This filter is the right addition to any aerator thru-hull intake that’s exposed to weeds, grass, or debris-heavy water — common in shallow bays, estuaries, and grass flats where tournament and inshore anglers spend most of their time. A clogged intake starves the aerator pump and kills bait fast; this filter keeps the flow clean without requiring you to pull the thru-hull fitting to service it. The twist-off design makes it practical to clean at the ramp or dockside between trips. If you’re building or upgrading a complete livewell aeration system, pair this filter with an Attwood Tsunami MK 2 Aerator Pump and the appropriate Attwood Livewell Spray Head for a complete flow-through setup, or the Attwood Tsunami Recirq Aerator Kit for a recirculating system that works at speed.
