Unscrew the two DIN 7984 bolts with a 2.5 mm Allen key to detach the propeller.
Check that the correct replacement propeller is used.
Secure the replacement propeller. Use the two DIN 7984 bolts with low-strength threadlocker
applied. Hand-tighten the DIN7984 bolts.

saltwater. Keep these environmental conditions in mind when performing the following procedures.

Check the motor bolts on the bottom of the arms.
Check the motor regularly for any excessive corrosion. It is recommended that you perform this
