Alpha Patrol Boat
• Fully dry the inside and outside of the boat, including
the water cooling lines and jacket around the motor.
Remove the hatch before storing your boat
• Repair any damage or wear to the boat
• Lubricate the driveshaft using Pro Boat Marine
Grease (PRB0100)
• Make note of lessons learned from the trimming of
your boat, including water and wind conditions
Tip:
The hook and loop strips in the boat retain water.
To dry them, press on them with a dry cloth.
NOTICE:
When you are finished boating, never leave
the boat in direct sunlight or in a hot, enclosed area
such as a car. Doing so can damage the boat.
After Boating and Maintenance
Drivetrain Lubrication
Always replace the drivetrain parts when they are
damaged or show visible wear or injury and damage
may result.
Lubricating the driveshaft 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.
1.
Use a #1 Phillips screwdriver to remove the 4 screws
from the
LEFT
side jet pump nozzle.
2.
Hold the jet pump nozzle at the base and gently pull it
away from the hull to unhook it from the steering link.
3.
Use a #1 Phillips screwdriver to remove the 4 screws
from the
RIGHT
side jet pump nozzle.
Tip:
When removing the right side jet pump nozzle,
move the servo arm so that it provides slack to the
steering link and allows you to pull the nozzle away
from the boat. You do not need to completely
remove the steering links from the right side jet
pump nozzle to service the propeller shaft.
4.
Use a 2mm hex driver to remove the 6 screws from
the rear hatch.
5.
Gently lift the rear hatch by the fuel drums.
Tip:
If the rear hatch does not come off easily, make
sure the 6 screws are completely removed from the
hull.
6.
Use a 2mm driver to remove the grub screw from
the shaft side of the motor coupler. You do not need
to remove the grub screw from the motor end of
the coupler unless you are removing the motor or
replacing the coupler.
7.
Free the propeller drive shaft from the motor coupling
and gently grip the shaft to pull it away from the
motor coupler.
8.
Lubricate the half of the propeller shaft that
inserts into the motor coupling with marine grease
(DYNE4200 or DYNE4201).
Tip:
There is no need to lubricate more than half of
the length of the propeller shaft because only half
of the propeller shaft is contained in the jet pump
housing.
IMPORTANT:
Excessively greasing the shaft can
cause grease accumulation in the jet pump housing,
which can cause water-flow restriction through the
jet pump. This will not cause damage to the drive
system, but it may decrease water flow through the
jet pump, or attract debris causing it to stick to the
grease.
9.
Reinsert the propeller shafts into the pump housing
using the hole on the motor coupler where the grub
screws thread as a guide to find the flat spot on the
drive shaft. You can also use this hole as a guide as to
how far to insert the shaft into the coupler.
IMPORTANT:
Ensure that the flat spot on the shaft
is oriented correctly. Do not screw in the motor
coupler grub screw until Step 12.
WARNING:
Do not push the propeller shaft
too far into the coupling or it can bind against
the jet pump housing, causing damage.
10.
Lubricate the jet pump nozzle bushing with a small
dab of marine grease. This metal bushing supports the
rear end of the driveshaft.
11.
Use a #1 Phillips screwdriver to carefully reinstall each
jet pump nozzle.
12.
Use a 2mm hex driver to install and tighten the motor
coupler grub screws.
13.
Power the boat and apply a small amount of throttle
to ensure the shafts are inserted properly.
Do not
touch the pump housing.
14.
Replace the access rear hatch and use a 2mm hex
driver to tighten the 6 screws.
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.
