Outboard drive for boats
Abstract:
An outboard drive for boats, having a steerable underwater housing (1) which has a wing-profiled portion (2). Projecting at an approximately 90 degree 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 travel in the water. The face portion is configured on that side of the profile which produces a lifting force counter-directional to a steering force, deriving from the motor torque, upon the wing profile.
