Blackjack 42 8S Catamaran - Manual

Troubleshooting Guide
Problem Possible Cause Solution
Boat will not respond to
throttle but responds to other
controls
Throttle channel is reversed Reverse throttle channel on transmitter
Extra noise or extra vibration
Damaged propeller, shaft or motor Replace damaged parts
Propeller is out of balance Balance or replace propeller
Reduced runtime or boat
underpowered
Boat battery charge is low Completely recharge battery
Boat battery is damaged Replace boat battery and follow battery instructions
Blocking or friction on shaft or propeller Disassemble, lubricate and correctly align parts
Boat conditions may be too cold Make sure the battery is warm (above 10º C [50º F]) before use
Battery capacity may be too low for
conditions
Replace battery or use a larger capacity battery
Drive dog is too near the prop strut
Loosen motor coupling on flex shaft and move flex shaft a
small amount
Too little lubrication on flex shaft Fully lubricate flex shaft
Vegetation or other obstacles block
the rudder or propeller
Remove vegetation or obstacles from rudder or propeller
Boat will not Bind (during
binding) to transmitter
Transmitter is too near boat during binding
process
Move powered transmitter a few feet from boat, discon-
nect and reconnect battery to boat
Boat or transmitter is too close to large
metal object, wireless source or another
transmitter
Move the boat and transmitter to another location and
attempt binding again
Another compatible transmitter is pow-
ered on within range of the receiver
Power off all compatible transmitters except the one you
are trying to bind
Boat battery/Transmitter battery charge
is too low
Replace/recharge batteries
ESC switch is off Power on ESC switch
Boat will not connect (after
binding) to transmitter
Transmitter is too near boat during
connecting process
Move powered transmitter a few feet from boat,
disconnect and reconnect battery to boat
Boat or transmitter is too close to large
metal object, wireless source or another
transmitter
Move boat or transmitter to another location and attempt
to connect again
Boat battery/transmitter battery charge is
too low
Replace/recharge batteries
ESC switch is off Power on ESC switch
Boat tends to dive in the
water or takes on water
The boat hull is not completely closed
Dry out the boat and ensure the hatch is fully closed on the
hull before returning the boat to the water
Center of gravity is too far forward Move batteries back in the hull
Boat tends to turn one
direction
Rudder or rudder trim is not centered
Repair rudder or adjust rudder and rudder trim for straight
running when control is at neutral
Rudder does not move
Rudder, linkage or servo damage Replace or repair damaged parts and adjust controls
Steering servo wire is damaged or con-
nections are loose
Do a check of steering servo wires and connections,
connect or replace as needed
Transmitter is not bound correctly Re-bind
BEC (Battery Elimination Circuit) of the
ESC is damaged
Replace ESC
ESC switch is off Power on ESC switch
Controls reversed Transmitter settings are reversed
Do the Control Direction Test and adjust controls on
transmitter appropriately
Motor overheats Blocked water cooler tubes Clean or replace water tubes
Motor power pulses then
motor loses power
ESC uses default soft Low Voltage Cutoff
(LVC)
Recharge boat battery or replace battery that is no longer
performing
Weather conditions might be too cold Postpone until weather is warmer
Battery is old, worn out or damaged Replace battery
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.
In the hull, use 2 12mm open-end wrenches to loosen the collet nut from the flex shaft.
Remove the two screws that secure the propeller strut from the mounting arm and the break away screw. Rotate the rudder up.
3. Slide the flex shaft and propeller strut down and out from the stuffing tube towards the rear of the boat. Tip: Use paper or cloth
for cleaning and lubricating the flex shaft and other drivetrain parts.
4. Wipe the old lubricant and material from the flex shaft.
5. 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.
6. Carefully reinstall the flex shaft and the drive strut into the 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.
Note: It is a good idea to check the breakaway screw for any wear and replace if necessary.
Note: If your flex shaft is not perfectly aligned with the collet, add shims to the stuffing tube support to center the flex shaft to the
collet.
