Maintenance
Always replace the driveshaft when it is damaged or
shows visible wear or injury and 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 tube.
Lubricate the shaft and all moving parts after every 2–3
hours of operation. Always replace any parts that show
visible wear or damage.
1. Loosen the setscrew holding the driveshaft in the
motor coupling and remove the driveshaft from the
back of the boat.
Tip: Remove the nut, screw, pin and rudder
from the rudder mount to remove the driveshaft
more easily.
Tip: Use paper or cloth to touch the
driveshaft.
2. Remove the driveshaft by sliding it out of the
stuffing tube. Wipe lubricant and material from
the shaft. Lubricate the full length of the shaft
assembly up to the drive dog using marine
grease (PRB0101 or PRB0100).
3. Carefully reinstall the driveshaft, ensuring that
there is a 1–2mm gap between the prop strut and
the drive dog.
4. Apply threadlock to the coupling setscrew and do
not over tighten. Threadlock will help prevent the
driveshaft from loosening during use.
NOTICE: Running the boat in saltwater could
cause some parts to corrode. If you run the boat
in saltwater, rinse it thoroughly in freshwater
after each use and lubricate the drive system.
NOTICE: Because of its corrosive effects,
running RC boats in saltwater is at the
discretion of the modeler.

or moisture may allow mold
and mildew to grow in the boat.
