2. Use two 10mm open end wrenches to

loosen the ferrule that secures the flex

shaft to the motor.

3. Remove the flex shaft by pulling it out

of the stuffing box by the propeller.

4. Use a paper towel and rubbing alcohol

to clean the flex shaft.

5. Apply a waterproof marine grease to

the flex shaft. We recommend the Pro

Boat marine grease available at your local

hobby dealer.

6. Reverse the previous steps to reinstall

the flex drive. Check that there is a

slight gap of 1/32-inch (1mm) between

the stuffing box and propeller mount as

shown. Also make sure the rudder mount

is parallel to the rudder bracket when

installed.
