摘要： In an engine, a cover member closing an opening in an engine block is integrally formed with supporting arms extending radially outwards beyond an outer periphery of a flywheel mounted on a crankshaft supported at its one end on the cover member, and a recoil starter located axially outside the flywheel is supported on the supporting arms. Thus, the recoils starter can be supported easily and reliably without provision of a special mounting bracket and a stay and while preventing the interference with the flywheel. Moreover, the coaxiality of the recoil starter and the crankshaft can be ensured.

摘要： An oil pan-coupled surface 115 formed on a lower surface of an engine block 11 having a crankshaft 15 supported to be directed vertically is extended below a cylinder head 12 beyond a line L extending downwards from a cylinder head-coupled surface 114 formed on a rear surface of the engine block 11. Thus, it is possible to increase the area of the oil pan-coupled surface 115 without interference with the cylinder head-coupled surface 114 and to increase the volume of an oil pan 411 coupled to the oil pan-coupled surface 115. Moreover, the cylinder head-coupled surface 114 and the oil pan-coupled surface 115 are not continuous with each other and hence, there is no possibility that the sealing of the coupled surfaces 114 and 115 may be impeded.

摘要： An outboard engine system includes a case member which is disposed below an engine body and integrally provided with an oil pan opening upwards, and a passage wall extending vertically to define an exhaust gas passage through which an exhaust gas flows. A portion of an outer wall of the case member is formed by the passage wall, and a recess is provided in the outer wall of the case member with a portion of the passage wall facing the recess. The recess is covered with a plate member fixed to the outer wall of the case member, and a cooling water passage, through which cooling water flows, is defined between the plate member and the recess. Thus, the passage wall integral with the oil pan is cooled effectively, while avoiding increases in size and weight.

摘要： An outboard motor hydraulic mechanism having a hydraulic actuator moving the outboard motor about a rotary shaft relative to a boat the motor is mounted on and a hydraulic pump and a plurality of electric motors connected to the pump. A number of the motors to be operated is determined based on an estimated load acting on the actuator, output shafts of the motors are aligned coaxially with a drive shaft of the pump, and they are directly connected with each other. This ensures that the operator is prevented from having an unpleasant feeling, lowers electric power consumption by the motors, and reduces the number of components and simplifies the structure of the mechanism.

摘要： An outboard motor steering system includes a hydraulic fluid supply mechanism connected to the steering hydraulic cylinder to supply hydraulic fluid thereto disposed in a space formed between the stern brackets and the swivel case. In other words, since the hydraulic fluid supply mechanism is incorporated into the outboard motor as a unit, the structure can be made simpler than that of the related art and the number of parts in the entire system can be reduced and moreover the work of installation into the boat's hull can be simplified. Also, operating efficiency is improved for an electric motor serving as the source of driving force for a hydraulic pump that supplies hydraulic fluid to the hydraulic cylinder used for steering, and power consumption is reduced.

摘要： In an outboard engine system in which a passage defining member having a passage wall defining an exhaust gas passage for guiding an exhaust gas from an engine is provided at its outer wall with a recess and a seal surface surrounding the recess; a fluid passage isolated from the exhaust gas passage is defined between the recess and a lid member which is mounted to the outer wall of the passage defining member with a seal member interposed between the lid member and the seal surface; and an exhaust gas sampling pipe is inserted into the exhaust gas passage through an insertion bore provided in the passage defining member to open into the seal surface, it is arranged that the seal member is formed to surround an opening at an outer end of the insertion bore, and the exhaust gas sampling pipe is gas-tightly fixed in the lid member to extend through the lid member. Thus, the exhaust gas sampling pipe can be inserted into the exhaust gas passage, while avoiding an increase in size of the lid member.
