摘要： An outboard motor cooling system wherein the coolant is circulated through the various cooling jackets so that it first flows into proximity with at least a portion of the exhaust system cooling jacket and then into the cooling jackets of the main engine body that cool the cylinder bore and combustion chamber. Sacrificial anodes are positioned both in the main engine body cooling jacket and in the exhaust system cooling jacket. In addition, a temperature sensor is positioned in a low portion of the cooling jacket and where the water has passed through the exhaust cooling jacket and before it enters the main engine body cooling jacket so as to provide accurate temperature indication while protecting the temperature sensor from excess temperature conditions particularly after engine shut off.

摘要： The present invention is an improved oil reservoir for an outboard motor. The oil reservoir is defined by an oil pan portion of an exhaust guide. The exhaust guide includes a support portion which is positioned below an engine powering the motor. The oil pan portion extends downwardly from the support portion. An opening provided in the support portion of the exhaust guide leads to the oil reservoir, serving as an oil return. Preferably, a gasket positioned between the exhaust guide and the engine partially obscures the opening, preventing backflow of oil from the reservoir into the engine when the motor is titled.

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.
摘要翻译： 用于船舶的舷外马达包括具有比现有燃料供应系统更小尺寸和更长寿命的简单结构化的燃料供应系统。 燃料供给系统包括由舷外马达承载的输送燃料箱。 燃料由位于舷外马达内的低压燃油泵从船舶所携带的外部燃料供给箱泵送到输送燃料箱。 控制系统控制低压燃料泵，使得在输送燃料箱中保持预定水平的燃料。 控制系统包括液位检测传感器，其检测输送燃料箱内的燃料水平并产生指示燃料液位的相应信号。 控制单元电路接收液位信号，并确定油箱中的液位是否高于或低于预定最大燃油量。 如果液面被确定为高于最大燃料液位，则控制单元电路使低压燃料泵无效。 如果液面被确定为低于最大燃料液位，则控制单元电路启动低压燃料泵。
