Problem
Possible Cause
Solution
Boat will not respond
to throttle but responds
to other controls

Remove motor and apply penetrating oil to both
ends of the motor. Rotate the motor shaft by hand
to break the corrosive bond between the motor
shaft and the bushings
Debris blocking a jet pump
Remove the jet pump nozzle, remove debris and
verify that nothing prevents the propeller from turning
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
Too little lubrication on driveshaft
Fully lubricate driveshaft
Vegetation or other obstacles block the
propeller
Remove vegetation or obstacles from propeller

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 battery back in the hull
Boat tends to turn one
direction
Debris is blocking a jet pump
Remove debris from the jet pump
Motor overheats
Bushings have seized
Lubricate motor bushings
Motor power pulses
then motor loses power
