5.5 Pylon
The motor and the electronic control system are located in the pylon. They generate the
propulsion. In addition, several protective functions are integrated:
1. Temperature protection: If the motor overheats, the motor control system reduces
the output of the drive until a temperature equilibrium is established between genera-
ted and disposed heat. Above a critical temperature the motor stops and the display
shows error code E02 or E08.
2. Under-voltage protection: If the voltage falls below 18 V for Cruise 2.0 models or 36 V
for Cruise 4.0 models (or under 21 V / 42 V if the motor is run with lithium batteries),
the electronic controller switches the drive off to prevent over-discharging the batte-
ries. The display shows error code E43.
3. Blocking protection: If the propeller is blocked or stuck, the motor would nor-
mally take in too much power. In this case, the motor is switched off within a few
hundredths of a second to protect the electronics, motor winding and propeller. After
removing the blockage you can switch the motor on again. If there is a blockage the
display shows error code E05.
4. Cable break protection: If the connection cable is damaged, i.e. if the connection to
the remote throttle is broken the motor will not start, respectively it will stop. An error
code is shown on the display.
5. Throttle control: The speed at which the propeller adjusts to a changed throttle posi-
tion is limited in order to protect mechanical drive parts and to avoid short-term peak
current.
• In case of motor malfunctions, an error code will pop up on display.
After elimination of malfunction, motor may move on from stop positi
on. Please refer to chapter 5.3.4. for any description and details.
Fin supports steering motion and secures propeller in case of ground contacts.
• Only run the motor when propeller is under water. If propeller moves
in air for longer periods, shaft sealant rings that seal the motor to the
drive shaft may be damaged and motor itself may be overheated.
• Always take the motor out of the water when not using it. To do so,
you may use the tilt mechanism of transom mount.
