Prop Angle Adjustment
Raising the prop strut increases speed, but also
decreases steering response and increases cavitation.
Lowering the prop strut increases steering response, but
also increases steering sensitivity and decreases speed.
1. Remove 3 bolts and 3 nuts on the prop strut on the
bottom 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.
Drivetrain Lubrication
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. Lubricate the prop shaft after
every 90 minutes of operation.
1. Remove 3 nuts and 3 screws from the prop strut on
the bottom of the boat.
2. Slide the strut down out of the mount.
Tip: Use paper or cloth to touch the flex shaft and other
lubricated parts.
3. Remove the flex shaft by sliding it out of the clutch,
the stuffing tube and the prop shaft. Mark or
otherwise note the flex shaft end in the clutch.
4. Loosen the set screw of the drive dog using a 2mm
hex driver.
5. Remove the nut, propeller and drive dog from the prop
shaft.
6. Remove the prop shaft and 2 bushings from the prop
strut.
7. Wipe lubricant and material from the shafts. Lubricate
the flex shaft, prop strut and prop shaft using marine
grease (PRB0101 or PRB0100).
NOTICE: Ensure the correct flex shaft end is inserted in
the clutch. Failure to do so may result in damage.
8. Assemble in reverse order. Tighten the drive dog set
screw on the flat spot on the prop shaft, applying
threadlock as needed.
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.
