Lubricating the Flex Shaft
Lubricating the drive system is vital to the life
of the drivetrain. The lubricant also acts as a
water seal, keeping water from entering the
hull through the stuffing box.
Lubricate the drive shaft, propeller shaft
and all moving parts after every 2–3 hours
of operation.
 1. Use two 10mm open-end wrenches to
loosen the ferrule that secures the flex
shaft to the motor.
 2. Remove the flex shaft by pulling it out
of the stuffing box by the propeller.
 3. Use a paper towel and rubbing alcohol
to clean the flex shaft.
 4. Apply a waterproof marine grease to
the flex shaft. We recommend the Pro
Boat marine grease available at your local
hobby dealer.
 5. 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.
