  NOTICE
  
  You should remove the anode from the motor before cleaning it with a wire brush or sandpaper. Cleaning the anode while it is installed on the motor could damage the motor, accelerate corrosion, and shorten the life of the motor.
- If the anode is smaller than half of its original size, discard the anode and purchase a replacement.

You can contact Garmin^® Support at support.garmin.com to purchase replacement anodes.

When reinstalling the propeller on the propeller drive motor, you must tighten the propeller nut to 16.27 N-m (12 lbf-ft.) to secure it properly.
