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
