Abstract
A hybrid drive for a watercraft, including a primary drive motor, which is situated inside the watercraft and drives a drive shaft, and an above-water transmission, which is situated after the drive shaft and has a transmission housing, for driving a vertical shaft branching off from the above-water transmission, as well as an electric secondary drive motor, which has a stator and a rotor and is able to drive the vertical shaft in addition to or alternatively to the primary drive motor. The secondary drive motor can be embodied with a hollow shaft and the stator of this motor can be coupled in a torsionally rigid fashion to the transmission housing of the above-water transmission.
