Setup and Installation
Unpacking
Carefully remove all components from the packaging. Verify that all parts listed in the packing list are present. Retain packaging for future storage or transport.
Mounting the Motor
The FW46 FB is designed for bow mounting. Ensure the mounting surface on your boat is flat and strong enough to support the motor's weight and thrust. Use appropriate stainless steel fasteners (not included) to secure the mounting bracket to the boat's bow. Position the motor so that the propeller is submerged at the desired depth when deployed.
Electrical Connection
Connect the motor's power leads directly to a 12-volt deep cycle marine battery. Ensure proper polarity: red to positive (+), black to negative (-). Use appropriate gauge wiring and a circuit breaker (recommended) to protect the system. Consult a qualified marine electrician if unsure about wiring.
Operating Instructions
Deployment and Stowage
To deploy the motor, release the locking mechanism and pivot the motor down until it locks into the deployed position. To stow, reverse the process, ensuring the motor is securely latched in the stowed position before moving the boat.
Foot Control Operation
The FW46 FB features a foot control pedal for hands-free operation. Press the pedal forward to increase speed and backward to decrease speed. Steer the boat by pivoting the pedal left or right. The momentary switch engages the propeller only while pressed, while the constant-on switch keeps the propeller running.
Speed Control
The motor offers variable speed control. Adjust the speed by rotating the speed control knob on the foot pedal or by varying pressure on the pedal, depending on the specific model variant.
Maintenance
After Each Use
Rinse the motor shaft and propeller with fresh water after each use, especially after operating in brackish or saltwater environments, to prevent corrosion. Inspect the propeller for fishing line or debris and remove if present.
Propeller Care
Periodically check the propeller for nicks, cracks, or bends. Replace damaged propellers to maintain efficiency and prevent vibration. Ensure the propeller nut is securely tightened.
Electrical Connections
Inspect all electrical connections for corrosion or looseness. Clean terminals and apply dielectric grease as needed to ensure good conductivity.
Shaft and Mount
Lubricate pivot points on the mounting bracket and shaft with a marine-grade lubricant annually or as needed to ensure smooth operation.
Troubleshooting
Motor Not Running
- Check Battery: Ensure the battery is fully charged and connections are clean and tight.
- Check Circuit Breaker: Verify the circuit breaker (if installed) has not tripped.
- Check Foot Pedal: Ensure the foot pedal is properly connected and functioning.
Reduced Thrust
- Propeller Fouling: Inspect the propeller for weeds, fishing line, or other debris.
- Damaged Propeller: Check for bent or broken propeller blades.
- Low Battery: Recharge or replace the battery.
Excessive Noise/Vibration
- Damaged Propeller: Replace the propeller if it's bent or unbalanced.
- Loose Mount: Tighten all mounting bolts.
