11.2 MOTOR MAKES EXCESSIVE NOISE OR VIBRATION
• Propeller may 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.
11.3 MOTOR FAILS TO RUN
• 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 damaged.
11.4 MOTOR LOSES ONE OR MORE SPEEDS
• Loose wire on rotary switch. Check wiring diagram.
• Loose connection in top housing.
• Rotary switch damaged.
• Speed coils in lower unit may be burned.
12 ABOUT CIRCUIT BREAKER
During the usage of the electric outboard motor, the propeller
can sometimes get stuck in weeds, fishing lines, or fishing nets.
Sometimes, due to the variance of the water depth, the propeller can
become covered in silt. If those situations occur, quickly disconnect
the battery and clean the propeller. (Please DO NOT increase the
thrust of the electric outboard motor to solve the problem, or it may
cause permanent damage to the electric outboard motor.)
The characteristics between the electric outboard motor and gasoline
outboard motor are dierent. If the motor’s propeller gets stuck, the
gasoline outboard motor will shut down to not cause any permanent
damage to the motor itself. However, the electric outboard will draw
extremely large current due to the motor stall and can generate large
amounts of heat that can damage essential components in the motor,
such as the switch, rotor, and other connecting parts, or even cause
serious battery explosions.
In some muddy water areas, it can be challenging for the user to
recognize that the motor is stalled. To prevent these situations from
occurring, it is strongly recommended to use a circuit breaker to
protect the electric outboard motor. If the electric outboard motor’s
current draw exceeds the normal usage limit, the circuit breaker will
cut o the power automatically to prevent any possible damage to
the electric outboard motor. The circuit breaker has a reset button
and is therefore reusable.
To prevent the rotor coil damage from exceeding current, it is
highly recommended to use a circuit breaker to protect the electric
outboard motor.
