5.4 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. 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.
3. Cable break protection: If the connection cable is damaged, i.e. if the connection to re-
mote throttle, battery or motor is broken, the motor does not start or stops. The error
code E30 or E32 appears.
4. Throttle control: The propeller rev change responds slowly to protect mechanical drive
components and avoid short-term power peaks.
5. Location sensor: The Ultralight has an integrated protective device that switches the
motor off when it is at a particular slope (90°). This prevents the propeller turning if
the boat capsizes or tilts further.
The fin supports steering movements and protects the propeller when it comes into con-
tact with the bottom.
• Only run the motor when the propeller is under water. If it is run in the
air, the shaft sealant rings that seal the motor to the drive shaft may
become damaged. If the motor is run in the air for a longer period, the
motor itself can overheat.
• After use, always take the motor out of the water.
The tipping mechanism can be used for this.
