  4. Using a 3 mm hex key, remove and examine the propeller drive anode 2.
  5. Select an option:

    • If either anode is half of its original size or larger, clean it using a wire brush or sandpaper.

      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 purchase a set of replacement anodes at garmin.com/accessories/force_current_trolling_motor.

NOTICE

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.
