2. Zinc Sacrificial Anode Replacement

The Actuators on each controller have zincs that need to be periodically inspected and replaced when about half of the anode has worn down. Zincs can be purchased through Seakeeper. To replace the zinc sacrificial anodes:

1. Remove the Blade by unscrewing the four (4) M8-1.25 x 20 mm screws and their washers.

2. Unscrew the two (2) M4-0.7 x 12 mm bolts holding the Zinc Sacrificial Anode.

3. Attach the new zinc sacrificial anode using the two (2) M4-0.7 x 12 mm bolts and tighten to 20 in-lbs (2.3 N-m).
4. Reattach the Blade using the four (4) M8-1.25 x 20 mm screws and their washers. Be sure to use thread locking sealant with an activator/primer when reinstalling hardware. Torque these four (4) bolts to 80 in-lbs (9.0 N-m) in an “X” pattern.
