Abstract
An outboard engine assembly has a stern bracket adapted to be fixed to a boat body, a swivel case vertically swingably supported on the stern bracket, an engine body laterally swingably supported on the swivel case, and a tilt cylinder device disposed between the stern bracket and the swivel case. The outboard engine assembly has a corrosion-resistant mechanism comprising a first anodic metal element attached to a lower portion of the engine body, a second anodic metal element attached to a submersible portion of the stern bracket, a first electric connecting circuit by which the first and second anodic metal elements are electrically connected to each other, and a second electric connecting circuit branched from the first electric connecting circuit and connecting the first electric connecting circuit to the tilt cylinder device. The tilt cylinder device comprises a cylinder unit actuatable by a pressurized fluid supplied from a pressure fluid supply. The cylinder unit is disposed substantially centrally in a planar region defined by the swivel case and lying parallel to a tilt shaft pivotally connecting the case and the swivel bracket. The pressure fluid supply is divided and disposed on both sides of the cylinder unit. The tilt cylinder device comprises a cylinder coupled to the swivel case, a piston rod coupled to the stern bracket. The outboard engine assembly has a damage preventing mechanism for allowing relative movement of the cylinder and the piston rod when the engine body is subjected to an excessive external force.
