Installation and Setup
Proper installation is crucial for the optimal performance and longevity of your washdown pump kit. Please follow these guidelines carefully.
Safety Precautions
- Ensure the vessel's power supply is disconnected before beginning installation.
- Wear appropriate personal protective equipment (PPE).
- Consult a qualified marine technician if you are unsure about any step.
Mounting the Pump
- Select a dry, well-ventilated location above the waterline, protected from direct spray.
- Mount the pump securely using appropriate fasteners, ensuring it is easily accessible for maintenance.
- Ensure the pump is mounted with the motor above the pump head to prevent water ingress into the motor.
Plumbing Connections
- Connect the inlet strainer to the pump's inlet port. Ensure the strainer is installed before the pump to protect it from debris.
- Connect the water supply hose from your vessel's raw water intake to the inlet strainer. Use marine-grade hose and clamps.
- Connect the coiled washdown hose to the pump's outlet port.
- Install the bulkhead fitting with valve in a convenient location on the deck or transom for easy access to the spray nozzle.
- Attach the spray pistol to the coiled hose.
- Ensure all connections are tight and leak-free.
Electrical Connections
- Connect the pump to a 12V DC power source.
- Install the illuminated panel switch in a suitable location.
- Wire the pump through the panel switch and an appropriately sized fuse or circuit breaker (not included) to protect the circuit. Refer to the pump's label for recommended fuse size.
- Ensure all electrical connections are secure, insulated, and protected from moisture.
Operation
Follow these steps to operate your Johnson Pump Aqua Jet Wash Down Pump Kit.
- Ensure all plumbing connections are secure and the water intake is submerged.
- Turn on the power to the pump using the illuminated panel switch. The pump will prime itself and build pressure.
- Open the valve on the bulkhead fitting and activate the spray pistol to begin washing.
- Adjust the spray pattern on the nozzle as needed.
- When finished, close the valve on the bulkhead fitting and turn off the pump using the panel switch.
- Release any remaining pressure in the hose by briefly activating the spray pistol after the pump is off.

Maintenance
Regular maintenance ensures the longevity and efficient operation of your washdown pump kit.
- Inlet Strainer: Periodically inspect and clean the PUMProtector inlet strainer to remove any debris that may restrict water flow or damage the pump.
- Hose and Nozzle: Rinse the coiled hose and spray pistol with fresh water after each use, especially after use in saltwater, to prevent salt buildup and corrosion.
- Connections: Regularly check all plumbing and electrical connections for tightness and signs of wear or corrosion. Replace any worn components.
- Winterization: In freezing climates, ensure the pump and all associated plumbing are completely drained or winterized with non-toxic antifreeze to prevent damage from ice expansion.
- Pump Inspection: Annually inspect the pump for any signs of leaks, unusual noises, or reduced performance.

Troubleshooting
This section provides solutions to common issues you might encounter with your washdown pump kit.
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not run | No power, blown fuse, loose wiring, faulty switch | Check power supply, inspect fuse/breaker, verify wiring connections, test switch. |
| Low or no water flow | Clogged inlet strainer, air leak in suction line, kinked hose, clogged nozzle, low voltage | Clean strainer, check all suction connections for leaks, straighten hose, clean nozzle, ensure adequate voltage. |
| Pump runs continuously (cycles) | Leak in discharge line, faulty pressure switch, air in system | Check for leaks in hose/fittings, inspect pressure switch, bleed air from system. |
| Excessive noise/vibration | Loose mounting, air in system, debris in pump head | Secure pump mounting, bleed air, inspect pump head for foreign objects. |
