Boat propulsion unit comprising a suspension arrangement (2) and a propeller drive shaft housing (3) which, via a lower and an upper universal joint (22, 24 resp.), are pivotally connected to each other. A hydraulic piston-cylinder arrangement (35) has its cylinder connected to the upper joint and, at the lower end of its piston rod, presents a forked bracket (39) which is pivotally connected to an upper region of the drive shaft housing. At a distance from the upper joint (24), the cylinder (34) of the arrangement presents attachments for a steering mechanism, by means of which the arrangement is displaceable about a vertical axis (a). The embodiment implies that the piston-cylinder arrangement serves both as a trim and tilt cylinder as well as a rudder. |
