摘要： The invention relates to a rotatable propeller drive (1) for a boat, where said propeller drive (1) comprises: - an upper fixing plate (4) adapted for rotationally fixed attachment to the hull bottom (2) of the boat; - a lower underwater housing (6) on which at least one propeller (10, 10a, 10b) is mounted, which underwater housing (6) is mounted rotatably in the fixing plate (4) about an essentially vertical axis of rotation (8), and - an exhaust duct (50) provided with an exhaust exit (14) located in the underwater housing (6). The invention is characterized in particular in that the exhaust duct (50) has: - an upper duct section (54) which extends through the fixing plate (4) and has an outlet opening (62) located in proximity to an opposite inlet opening (60) in a lower duct section (56) which extends through the underwater housing (6), where one of said outlet opening (62) and inlet opening (60) overlaps the other at least within a limited first rotation angle range for the propeller drive (1), and - a sliding seal arrangement (58) adapted for sealing between said upper (54) and lower (56) duct sections, where said sliding seal arrangement (58) comprises a sealing element (64) accommodated in a seat (66) around one of said outlet opening (62) and inlet opening (60), which sealing element (64) has a contact surface (68) for sliding contact with an opposite sliding seal surface (70) around the other of said outlet opening (62) and inlet opening (60).

摘要： A method of steering a planning V-bottomed boat with double individually steerable outboard drive units with underwater housings (6), which extend down from the bottom (1) of the boat. When running at planning speed straight ahead, the underwater housings are set with 'toe-in', i.e. inclined towards each other with opposite angles (α) of equal magnitude relative to the boat centre line (b). When turning, the inner drive unit is set with a greater steering angle than the outer drive unit.

摘要： Propulsion unit for marine vessels with a gear or bearing housing (6) in which a propeller shaft (7) with a surface-breaking propeller (8) is carried. In a horizontal plane the propeller shaft forms an angle (α) to a guide fin (9) so as to create a resultant force (R) of the pressure force (P) of the propeller and the side force (S), with the resultant force being aligned with the longitudinal direction (CL) when the vessel is travelling straight ahead.

摘要： An outboard drive for boats, having a steerable underwater housing (1) which has a wing-profiled portion (2). Projecting at an approximately 90° angle from the aft part of one side face (31) of the wing profile is a face portion (32), the lateral extent of which amounts to about 1-2% of its distance to the steering shaft (36) of the wing profile. As a result of this construction, a lifting force will be generated during forward traved in the water. Said face portion is configured on that side of the profile which produces a lifting force counterdirectional to a steering force, deriving from the motor torque, upon the wing profile.

摘要： A control system for an engine transmission provided with a coupling mechanism for engaging or disengaging coupling of the transmission. The control system has one or more valves movable between two positions for controlling engagement and disengagement of the coupling mechanism. The valves are connected to an automatic control unit which has an intermittent signal supply trigger for supplying an intermittent pulsed signal to the valves, thereby providing an intermittent movement of the valves between the two positions.
