7.3 Changing the propeller
1. Disconnect the motor cable from the battery.
2. Use a socket wrench, metric socket size 17 (11/16“ for the US), to unscrew the self-
locking hexagonal nut on the propeller. Hold the propeller with protective gloves (risk
of injury).
3. Remove the propeller and the outer washer from the motor shaft.
4. Pull the cylindrical pin out of the motor shaft and remove the inner washer from the
motor shaft.
5. Reconnect the motor cable to the battery and switch the motor on. Let the motor run
slowly and check at the shaft sealing ring whether the shaft rotates evenly. Take care
that no loose clothing, scarves or other clothing as well as hair can catch in the motor
shaft and be pulled in. In case of damage or if the shaft or sealing rings rotate out of
true, contact Torqeedo Service.
6. Disconnect the motor cable from the battery. Place a new washer onto the motor shaft
and insert the new cylindrical pin into the centre of the motor shaft.
7. Place the propeller onto the motor shaft as far as it will go, so that the cylindrical pin
locks into the recess provided in the propeller.
8. Place the outer washer onto the motor shaft and screw the self-locking hexagonal nut
hand-tight onto the propeller. Hold the propeller with protective gloves (risk of injury).
