Horizon Harbor 30-Inch Tug Boat
Drive Shaft Maintenance
Quick Service
Always replace the drivetrain parts when they are damaged
or show visible wear or injury and damage may result.
Lubricating the drive 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 drive shaft, propeller strut and all moving
parts after 30 minutes of operation.
1. Open the main cabin hatch.
2. Locate the grease fitting just aft of the propeller shaft
coupler.
3. Attach the included silicone fuel tubing to the grease
fitting.
4. Apply a few pumps of grease onto the fitting, using a
Dynamite grease gun (DYNE4200).
Tip: Use paper towel to clean up excess marine grease.
Full Service
1. Use a 1.5mm hex driver to loosen the propeller
setscrew.
2. Hold the motor coupler to prevent the drive shaft
from spinning, and loosen the propeller by spinning it
counter clockwise.
3. Use a 1.5mm hex key to loosen the drive shaft from
the motor coupler.
4. Turn the kort nozzle so the drive shaft can be pulled
through it and toward the rear of the boat.
5. Clean the shaft using paper towels and rubbing
alcohol.
6. Lubricate the full length of the shaft using marine
grease (DYNE4201).
7. Assemble in reverse order.
Tip: Use paper towel to clean up excess marine grease.
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.
1. Use a 1.5mm driver to loosen the propeller setscrew.
2. Back off the 5.5mm nut from the propeller by turning
the nut clockwise.
3. Hold the driveshaft to prevent it from spinning, and
loosen the propeller by turning it counter clockwise.
4. Assemble in reverse order.
Tip: You may need to turn the kort nozzle in order to fully
remove the propeller from the shaft.
Propeller Service
If the boat does not go straight, adjust the ST TRIM
button on the transmitter.
If you are using all the steering trim on your transmitter
to make the boat drive straight, return the trim to neutral
and mechanically center the rudder. To do this:
1. Remove the center and rear hatches.
2. Loosen the setscrews on the servo horn.
3. Center the kort nozzle by hand.
4. Tighten the steering linkage on the servo horn.
