- Mark and drill holes according to the mounting plate template (not provided, assume standard).
- Secure the motor mount using the provided hardware, ensuring a tight and stable fit.
- Attach the motor unit to the mounted plate.
Battery Connection
A 12V, 105AH deep cycle battery is recommended (not included).
- Ensure the motor is in the "OFF" position before connecting the battery.
- Connect the positive (+) motor cable to the positive (+) terminal of the battery.
- Connect the negative (-) motor cable to the negative (-) terminal of the battery.
- Ensure all connections are tight and corrosion-free.
Propeller Installation
Install the propeller onto the motor shaft, securing it with the provided nut. Ensure it is tight but do not overtighten.

Troubleshooting
Refer to this section for common issues and their solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor does not turn on. | No power from battery; loose connection; remote control battery low. | Check battery charge; ensure all electrical connections are secure; replace remote control batteries. |
| Motor runs but thrust is weak. | Low battery charge; propeller fouled with weeds/line; damaged propeller. | Recharge battery; clear propeller; replace propeller. |
| GPS anchor function is inaccurate. | Poor GPS signal; strong currents/wind. | Move to an area with better GPS reception; understand limitations in extreme conditions. |
| Remote control not responding. | Remote battery low/dead; remote not paired; interference. | Replace remote batteries; re-pair remote control (refer to specific pairing instructions, if available); move away from sources of interference. |
