Setup
- Mounting the Motor: Securely attach the bow mount trolling motor to the bow of your boat. Ensure the mounting surface is strong enough to support the motor's weight and thrust.
- Battery Connection: Connect the motor to a 24V power source using two 12V deep cycle batteries (2 x 105AH suggested, not included) wired in series. Ensure all connections are tight and corrosion-free. Observe correct polarity.
- Shaft Length Adjustment: Adjust the shaft length using the depth collar to ensure the propeller is submerged to the optimal depth, typically at least 12 inches below the water surface, to prevent cavitation.
- Remote Control Pairing: Refer to the specific instructions provided with your remote control for initial pairing with the trolling motor.
- GPS Antenna: Ensure the GPS antenna (if external) is mounted in a clear, unobstructed location for optimal signal reception.

- Ensure propeller is submerged to the correct depth.
- Remote Control Not Responding:
- Replace remote control batteries.
- Re-pair the remote control with the motor according to the pairing instructions.
- Ensure no strong interference sources are nearby.
- GPS Anchor Not Holding Position:
- Ensure the GPS antenna has a clear view of the sky.
- Check for strong currents or winds that may exceed the motor's holding capacity.
- Verify GPS signal strength on the remote or app.
User Tips
- Always carry spare batteries for your remote control.
