摘要

The subject of the present invention is direct-propulsion equipment with an internal combustion engine for a boat, in which the engine and the propeller constitute a unit assembly capable of pivoting vertically and horizontally. It consists of a cradle (3) supporting the engine (2), that can pivot near the transom (16) of the boat (1) about a horizontal pivot axis (A2), the engine being coupled to a drive shaft (4) bearing the propeller (5) at its end, this entity being rendered non-deformable by virtue of two semi-circular lateral arms (6) centered on the pivot axis (A2) and each connected by a rear arm (7) to a chair (8) supporting the drive shaft and by a lateral arm (9) to the cradle (3) in order to cross-brace the assembly which is connected to an inverted bracket (15) attached to the inside of the transom (16) and allowing said assembly to rotate about a substantially vertical axis (A1). The invention relates to the industrial and commercial field of boat propulsion unit manufacture and distribution.
