Maintenance
Always replace the shaft when it is damaged or shows visible wear or injury and property damage may
result.
Lubricating the shaft 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 shaft, propeller shaft and all moving parts after every 2-3 hours of operation. Always replce
an parts that show visible wear or damage.
1. Align the propeller with the drive dog on the flex shaft, then
install the propeller using the included locknut.
2. Install the rudder horn to the rudder by two screw.
3. Install the rudder to the rudder holder and fix it by a bolt as
show in the graphic.
4. Connect the cooling line to the fitting on the top of the rudder.
5. Ensure the trim tab panel is either perpendicular to or parallel
to the bottom of the boat. If it’s needed to switch the angle of the
panel, tie or release the screw which is touch the panel to switch
the angle.
1. Loosen the coupling between the motor and the
shaft.
2. Loosen setscrew from the shaft and remove the
shaft from the back of the boat.
Tips: Use paper or cloth to touch the shaft.
3. Remove the drive shaft by sliding it out of the
stuffing box. Wipe lubricant and material from the
shaft. Lubricate the full length of the shaft assembly
up the drive dog with marine grease.
4. Apply threadlock to the coupling setscrew.
Threadlock will help prevent the shaft from loosening
during usage.
5. Carefully reinstall the drive shaft, ensuring that
there is a 1-2mm gap between the prop strut and the
drive dog to allow for shaft shrinkage under load.
NOTICE:
Running the boat in salt water could cause
some parts to corrode. If you run the boat in salt
water, rinse it thoroughly in fresh water after each use
and lubricate the drive system.
NOTICE:
Because of its corrosive effects, running RC
boats in salt water is at the discretion of the user.
