摘要： An improved and simplified outboard motor construction wherein the cooling and exhaust systems for the engine are formed with a minimum number of components and sealing joints and incorporating a non-metallic cam shaft for reduced cost and weight without sacrifice of durability. The exhaust system includes an elongated expansion chamber formed in the drive shaft housing. In addition, the drive shaft housing has a cylindrical section that is journaled within a swivel bracket for its steering movement. The volume between the external portion of the drive shaft housing and the internal portion of the swivel bracket forms a second expansion chamber that is employed for the low speed above the water exhaust gas discharge. The flow of cooling the water to and from the engine is controlled so that the exhaust gas interchange area between the power head and the drive shaft housing will be well cooled, as will the oil reservoir for the engine and the oil returned to it.

摘要： An outboard motor includes an improved engine layout to provide a compact power head while simplifying the arrangement of components on the engine. In one mode, an induction system of the engine includes a carburetor that is arranged over a cylinder head. An intake pipe connects the carburetor to an intake port of the cylinder head. The pipe has generally a U-shape and loops around the upper side edge of the cylinder head. An air intake device is arranged upstream of the carburetor to supply air thereto. The air intake device includes a downward facing air intake opening that is located along a side of the engine below the upper end. This arrangement of the induction system that extends over the upper side of the engine produces a compact assembly without overly complicating the arrangement of other components on the engine, such as, for example, a manual starter device. With the present engine layout, the manual starter device is positioned on an upper side of the engine in front of the carburetor near a crankshaft of the engine. The air intake opening faces a lower air vent formed in a cowling below the engine. Cool air flows through the lower air vent and is drawn into the air intake opening for engine operation. This flow of cool air also cools the engine. The cowling also includes an upper vent to expel warm air from about the carburetor on the upper side of the cowling and to promote a current of air across the engine for cooling purposes.
摘要翻译： 舷外马达包括改进的发动机布局以提供紧凑的动力头，同时简化发动机上部件的布置。 在一种模式中，发动机的感应系统包括布置在气缸盖上的化油器。 进气管将化油器连接到气缸盖的进气口。 该管通常具有U形并围绕气缸盖的上侧边缘环绕。 在汽化器的上游配置有进气装置，以向其供给空气。 进气装置包括向下的进气口，其位于发动机下方的上端的下方。 在引擎的上侧延伸的感应系统的这种布置产生紧凑的组件，而不会使发动机上的其它部件（例如手动起动装置）的布置过度复杂化。 根据目前的发动机布局，手动起动装置位于发动机的上侧，靠近发动机曲轴的化油器前方。 进气口面向在发动机下方的整流罩内形成的下部通风口。 冷空气流过下部通风口，并被吸入进气口进行发动机运转。 这种冷空气流也冷却发动机。 整流罩还包括一个上部通风口，用于从整流罩上侧的化油器周围排出温暖的空气，并促使空气流过发动机进行冷却。

摘要： A crankcase seal and ventilation arrangement for an outboard motor that permits ventilating air to flow from the crankcase chamber into an induction system of the engine for air purification. In addition, the arrangement is such that oil, which may flow into the ventilating air chamber when the outboard motor is tilted up, can return to the crankcase chamber when the outboard motor is returned to its normal running condition.

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.
