摘要： An oil pump for a lubricating system of an outboard motor is disclosed. The motor has a cowling defining an engine compartment, a water propulsion device, and a guide member having an upper surface and a lower surface, the guide member positioned in the cowling and generally dividing the engine compartment into an upper part and a lower part. An engine is positioned in the upper part of the engine compartment within the cowling and has an output shaft arranged to drive the water propulsion device. The lubricating system includes an oil pan positioned below the guide member and an oil passage leading from the pan through the guide member. The oil pump is positioned in the upper part of the engine compartment, but below the engine, and is driven by a lower end of the output shaft of the engine which extends below the engine, the oil pump having an oil inlet in communication with the oil passage through the guide member.

摘要： An outboard motor for a watercraft includes a simply structured fuel supply system of a smaller size and a longer life than prior fuel supply systems. The fuel supply system includes a delivery fuel tank carried by the outboard motor. Fuel is pumped from an external fuel supply tank carried by the watercraft to the delivery fuel tank by a low-pressure fuel pump located within the outboard motor. A control system controls the low-pressure fuel pump so that a predetermined level of fuel is maintained in the delivery fuel tank. The control system includes a fluid level detection sensor that detects the level of fuel within the delivery fuel tank and produces a corresponding signal indicative of the fuel level. A control unit circuit receives the fluid level signal and determines if the fluid level in the tank is higher or lower than a predetermined maximum fuel level. If the fluid level is determined to be higher than a maximum fuel level, the control unit circuit deactivates the low-pressure fuel pump. If the fluid level is determined to be lower than the maximum fuel level, the control unit circuit activates the low-pressure fuel pump.

摘要： A fuel injection system for an internal combustion engine of the type utilized to power an outboard motor of a watercraft is disclosed. The engine is oriented with its crankshaft vertically extending, such that the engine has a top and a bottom, a first end and a second end, and a side between the ends. An air delivery passage extends generally from the first end along said side to an intake passage leading through the engine to a combustion chamber therein. A fuel injector is positioned along the side of the engine and arranged to deliver fuel into air flowing through the passage. In one arrangement, the fuel injector is connected to an intake manifold defining at least a part of the air delivery passage and is adapted to deliver fuel opposite the flow of air through the passage at the point of delivery. In a second embodiment, the fuel injector is positioned between the air delivery passage and the side of the engine. In this embodiment, the fuel injector is preferably arranged to deliver fuel perpendicular to the flow of air through the passage.
