Propeller may be fouled.
Propeller by be damaged or unbalanced.
Check to see if propeller is secured.
Bent armature. Remove propeller, set at medium speed, turn unit on and check for armature wobble.
Turn propeller by hand. It should turn freely with a slight magnetic drag.
Bearing bushes may be worn out.
Check fuse circuit breaker on boat for electric motor.
Check for loose or corroded connections.
Check plug for loose or bad connection.
Test main rotary switch.
Turn prop by hand. It should turn freely with a slight magnetic drag.
Total battery failure. Recharge and check voltage.
Propeller Fouled.
Lose wire on rotary switch. Check wiring diagram.
Lose connection in top housing.
Rotary switch damaged.
Speed coils in lower unit may be burned.
PLEASE NOTE:
During the usage of the electric outboard motor, the propeller is possible to get stuck by the weeds,
fishing lines and fishing webs, or sometimes due to the variance of the water depth, the propeller is
covered by the silt. If those situations stated above happen, please disconnect the battery in time and
clean up the propeller. (Please DO NOT rise steps and increase the thrust of electric outboard motor
to solve the problem, or it may cause permanent damages to the electric outboard motor.)
The characteristics between the electric outboard motor and gasoline outboard motor are different, if
the propeller of the motor gets stuck, the gasoline outboard motor will only shut down and not cause
any permanent damage to the motor itself, however, the electric outboard will draw extremely large
current due to the motor stall and generate large amount of heat to damage important components in
the motor such as switch, rotor and other connecting parts or even cause serious battery explosions.
In some muddy water areas, user is hardly to recognize that motor is stuck and shut down the power.
To prevent these situations occur, it is strongly recommended to use circuit breaker to protect the
electric outboard motor. If the current draw of the electric outboard motor exceeds the limit of normal
usage, the circuit breaker will cut off the power automatically to prevent any possible damage to the
electric outboard motor. The circuit breaker has the reset button and is therefore reusable.
To prevent the rotor coil damage from exceeding current, it is highly suggested to circuit breaker to
protect electric outboard motor.
