An arresting element can be provided for determining a first desired distance along the shaft between the receiving device and the drive motor.

Abstract: The present disclosure relates to a folding propeller, comprising a hub, which may be driven via a drive shaft around a rotation axis, at least two propeller blades, which are pivotably arranged on the hub between a folded position and an unfolded position, and a propeller blade arresting means, which is configured for arresting the propeller blades in the unfolded position, wherein the propeller blade arresting means is movable relative to the hub in rotation direction between a starting position and an arresting position.

Abstract: The present disclosure relates to a drive arrangement for propelling a boat, for example a kayak, having an electric drive motor with a shaft, a receiving device for receiving the shaft and a holder for holding the receiving device on the boat. In some embodiments, the receiving device is pivotable for pivoting the electric drive motor between an operating position and a tilt position relative to the holder. A switchable fixing device is provided for fixing the receiving device in the operating position. The fixing device has an overload protection for disconnecting the fixing in the operating position when a predetermined pivot force in the direction of the tilt position is exceeded.
