Replacing the Stuffing Tube
We recommend replacing the brass stuffing tube if you
replace the drive shaft or if you notice wear or vibration in
the drive line.
1. Follow
Servicing the Drive Shaft
Steps 1–9.
2. Use a 2.5mm hex driver to remove both screws
from the motor mount.
3. Disconnect the motor wires and remove the motor
from the hull, placing the motor aside.
4. Using a 2mm L-shaped hex driver, loosen the jet
pump housing bolt until it is even with the nut holding
it in place.
Do not remove the bolt completely.
5. Insert the drive shaft into the brass stuffing tube,
applying minimal lateral force while simultaneously
pushing away from yourself.
NOTICE:
Applying too much force prevents the drive
shaft from entering the brass tube correctly.
WARNING:
Do not allow the drive shaft to
push the brass tube out the back of the pump.
Doing so could damage the pump webbing.
6. Install the new brass stuffing tube (from inside the
boat) pushing it toward the back of the boat. Verify
the brass tube sits inside the jet pump housing
support webbing.
NOTICE:
Do not push the brass tube flush with the
pump or you will damage the support webbing.
7. Follow
Servicing the Drive Shaft
Steps 10–20 to
reassemble the jet pump.
Water Cooling System
If water does not stream out of the water outlets while
the boat is moving forward, immediately stop the boat
and inspect the water cooling system.
1. Disassemble and clean the water cooling system to
remove blockage and prevent overheating.
2. Replace any damaged parts.
3. Inspect the system for loose connections, kinks or
tears in the line.
18. Apply a small amount of marine grease along the
steering and trim links. This allows them to slide into
the rubber bellows. After installation, remove any
excess grease.
19. Attach the ball ends of the steering and trim links to
the nozzle mechanics. Set the jet nozzle trim to the
stock setting.
Tip:
Power on your boat so that the steering servo
centers before tightening the steering link set screw
found on the steering servo arm.
20. Reattach the silicone cooling line to the brass fitting
on the jet pump housing.
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. You can also use water displacement spray
to help prevent the parts from corroding.
NOTICE:
Because of its corrosive effects, running RC
boats in saltwater is at the discretion of the modeler.
Corrosion is not covered under warranty.
