Boat propeller drive unit, comprising a frame-like carrier (1) intended to be fixedly joined to a boat transom, and a propeller rig (4) which is suspended in a fork (13) for trim and tilting movement relative to the fork about a horizontal axis (a). The fork in turn is mounted in the carrier for pivoting about a vertical steering axis (b). A pair of hydraulically operated piston cylinder devices (18,20) are pivotally joined at opposite ends to the rig (4) and to the legs (12) of the fork. |
