Abstract

The invention relates to a drive arrangement for an inboard-outboard drive engine of a watercraft, comprising a drive unit (2) having an upper part (3) arranged in the hull (1) of the water craft, and a lower part (4) protruding through a sealed opening in the hull (1) into the surrounding water. A drive train is guided inside the drive unit (2), by which means at least one screw provided on the lower part (4) can be driven by a motor arranged in the region of the upper part (3). The upper part (3) is also in contact with a carrier system supporting reaction forces and torques applied to the drive unit (2) in longitudinal, transversal and vertical directions during the operation of the watercraft, in relation to the hull (1), using a plurality of supporting units (12A-12D).
