Always replace the drivetrain parts when they are damaged or
show visible wear or injury and damage may result.
Lubricating the flex 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 flex shaft and all moving parts after every 30
minutes of operation. Remove, clean, and lubricate the flex
shaft after every boating session.
1. In the hull, use 2 12mm open-end wrenches to loosen the
collet nut from the flex shaft.
2. Slide the flex shaft out from the stuffing tube and drive
strut at the rear of the boat.
Tip:
Use paper or cloth for cleaning and lubricating the flex
shaft and other drivetrain parts.
3. Wipe the old lubricant and material from the flex shaft.
4. Lubricate the full length of the flex shaft assembly up to
the drive dog using marine grease (PRB0101 or PRB0100).
Also apply grease to the collet threads.
5. Carefully reinstall the flex shaft in the drive strut, stuffing
tube and collet. If the flex shaft is difficult to remove or
install in the collet, use a flat screwdriver to spread the
grips of the collet.
Ensure there is a 1–2mm gap between the drive strut and
drive dog to allow for flex shaft shrinkage under load.
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.
Drivetrain Lubrication
Prop Angle Adjustment
Raising the prop strut increases speed, but also decreases
steering response and increases cavitation.
Lowering the drive strut increases steering response, but
also increases steering sensitivity and decreases speed.
1. Loosen 2 bolts and 2 nuts from the drive strut on the
rear of the boat.
2. Slide the strut up or down to change the angle of the
propeller in relation to the hull.
3. Adjust as desired and tighten the nuts and bolts.
Tip:
Finding the proper prop angle will reduce the chance of
a blow over and/or porpoising.
