摘要： An engine for an outboard motor includes an oil filter. A first oil passage has a communication duct disposed at a position lower than that of the oil filter and communicating with a crank chamber. The communication duct is closed by a drain valve that can be opened and closed manually. Opening the drain valve allows the oil accumulated in the first oil passage to flow down into the crank chamber through the communication duct.

摘要： Recesses are provided in portions of a head cover and a crankcase which are opposed to outer peripheries of a timing chain and a balancer-driving chain driven by a crankshaft of a vertical engine, whereby vertical walls and horizontal walls are formed to oppose to outer peripheral surfaces and lower surfaces of the timing chain and the balancer-driving chain. An oil scattered from the timing chain and the balancer-driving chain by a centrifugal force is caught on the vertical walls, and the oil flowing down along the vertical walls by gravitation is retained on the underlying horizontal walls, whereby the oil can be brought into contact with the chains without waste to effectively lubricate the chains.

摘要： Oil jets are mounted in upper two cylinders in a cylinder block of a 4-cylinder vertical engine to inject an oil to rear faces of pistons received in the two cylinders. Thus, although lower pistons are cooled more effectively by the oil dropped by gravitation through oil return bores provided in journal support walls, the upper pistons are forcibly cooled by the oil injected from the oil jets, so that the four pistons can be cooled equally to prevent insufficient cooling and excessive cooling, while minimizing the required amount of the oil.

摘要： In a water-cooled multi-cylinder vertical engine for an outboard engine system, cooling water having passed through an exhaust-manifold cooling water jacket for cooling an exhaust passage within an engine room is supplied to a cylinder-block cooling water jacket provided in a cylinder block through water supply pipes, a branching member and two upper and lower couplings. In this case, the lower coupling is locked below the center of a lowermost cylinder to minimize unevenness in flow rate of the cooling water flowing through a water jacket on opposite left and right sides of a cylinder toward a cooling water outlet provided at an upper portion thereof, thereby making uniform the distribution of the temperature around a combustion chamber, leading to an enhancement in cooling effect.

摘要： A first chain mechanism for transmitting the rotation of a crankshaft of an vertical engine to a camshaft and a second chain mechanism for transmitting the rotation of the crankshaft to a balancer shaft are forcibly lubricated by an oil injected by first, second and third oil jets mounted within a chain chamber. The first, second and third oil jets are disposed at locations closer to the crankshaft, the cam shaft and the balancer shaft, respectively, and the first and second oil jets are disposed inside a travel locus for a timing chain. Thus, the chain mechanisms disposed in a plane of the vertical engine can be lubricated effectively.

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 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.
