    摘要： A gear housing for an aquatic vessel is adapted to be attached at an attachment site to an underside of a hull of the aquatic vessel. The gear housing includes at least one weakened region adapted to yield when the gear housing is rotated at the attachment site following an impact. A breakaway safety system includes such a gear housing, and a fracturable member for attaching the gear housing to the hull at the attachment site, wherein the weakened region is adapted to yield such that the fracturable member fractures. An aquatic vessel includes such a gear housing or such a breakaway safety system.

    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 marine propeller drive (1) for boats, including a gearbox (10) for a motor transmission and an associated impelling propeller (12), where said propeller (12) is provided with a propeller hub (14), the main peripheral cross-section dimension (A) of which is less than the main peripheral cross-section dimension (B) of the gearbox (10) and where a transition cone (18) is located between the gearbox (10) and the propeller hub (14). The transition cone (18) has: - a front end (20) located in connection with the gearbox (10), where said front end (20) has an initial peripheral cross-section dimension (C) essentially corresponding to the main peripheral cross-section dimension (B) of the gearbox (10); - a rear end (22) located in connection with the propeller hub (14), where said rear end (22) has a connecting peripheral cross-section dimension (D) essentially corresponding to the main peripheral cross-section dimension (A) of the propeller hub (14). The invention is distinguished in particular by the fact that the transition cone (18) includes a bulb-shaped shoulder part (24) located between said front end (20) and rear end (22), the largest peripheral cross-section dimension (E) of which exceeds the initial peripheral cross-section dimension (C) of the transition cone (18).
