    • An engine of an outboard motor includes an improved engine component layout to minimize the size of the engine and to generally isolate a shift position mechanism from an intake air flow into the engine. The outboard motor includes a shift actuation mechanism that shifts a transmission between three operational states: forward, neutral, and reverse. The shift actuation mechanism includes a shift position mechanism that defines the position of the shift actuation mechanism during each of these three operational states. The shift position mechanism is positioned beneath the engine crankcase and is formed in part by a shift lever of the actuation mechanism. This position and construction simplifies the design of the shift position mechanism and generally isolates the mechanism from any salt water or other contaminates the are entrained in the air flow stream within the cowling.
    • 舷外马达的发动机包括改进的发动机部件布置,以使发动机的尺寸最小化并且将换档位置机构与进气流大致隔离成发动机。 舷外马达包括换档致动机构,其将传动在三种操作状态之间转换:前进,中立和反向。 换档致动机构包括在这三个操作状态的每一个期间限定换档致动机构的位置的换档位置机构。 换档位置机构位于发动机曲轴箱的下方,并且由致动机构的变速杆部分地形成。 这种位置和结构简化了换档位置机构的设计,并且通常将机构与任何盐水或其他污染物隔离在整流罩内的空气流中。

    • A steering mechanism for an outboard motor which comprises a steering bracket having a mounting bore and a steering handle having a mounting shaft at one end that is received for pivotal rotation within the mounting bore. In one embodiment, a wave washer is positioned within a counterbore formed at the upper end of the mounting bore and coaxial therewith so that the wave washer is between the steering bracket and the steering handle. In another embodiment, a pair of rubber members are each positioned within one of a pair of counterbores that are coaxial with the mounting bore, one being formed at the upper end of the mounting bore and the other being formed at the lower end, so that the rubber members are interposed between the steering bracket and the steering handle. The wave washer and rubber members dampen vibration transmission between the steering bracket and handle, and permit pivotal adjustment of the handle up or down while still providing sufficient frictional resistance against inadvertent pivotal movement of the handle. An area of rigid contact is positioned radially outward of the upper counterbore between the steering handle and the steering bracket to provide a highly responsive steering mechanism.
    • 一种用于舷外马达的转向机构,其包括具有安装孔的转向支架和转向手柄,所述转向手柄在一端具有安装轴,所述安装轴被容纳在所述安装孔内以枢转旋转。 在一个实施例中,波形垫圈定位在形成在安装孔的上端并与其同轴的沉孔内,使得波形垫圈在转向支架和转向手柄之间。 在另一个实施例中,一对橡胶构件各自定位在与安装孔同轴的一对沉孔内的一个中,一对橡胶构件形成在安装孔的上端,另一个形成在下端,使得 橡胶构件设置在转向支架和转向手柄之间。 波形垫圈和橡胶构件抑制转向支架和手柄之间的振动传递,并且允许手柄向上或向下枢转调节,同时仍然提供足够的摩擦阻力以防止手柄的无意的枢转运动。 刚性接触区域位于转向手柄和转向支架之间的上沉孔的径向外侧,以提供高响应性的转向机构。

    • A cowling assembly for an outboard motor includes an improved construction that can supply relatively cool air containing little water to the induction device and can also supply air to cool engine components without reducing the charging efficiency. The outboard motor has an engine that includes an air induction device and is enclosed within the cowling. The cowling assembly defines a closed cavity in which the engine is contained and has an air intake system. An air intake duct structure introduces air into the cavity. The intake duct structure includes a plurality of relatively narrow connection passages and has an expansion chamber portion disposed on the downstream side of the passages. Intake noise is reduced by this construction. In one preferred form, the cowling assembly additionally has a second intake system. One or more connection passages communicate with the first air intake system and the second air intake system.
    • 用于舷外马达的整流罩组件包括改进的结构,其可以向感应装置提供相对较少的含有少量水的空气,并且还可以在不降低充电效率的情况下将空气供应到冷却发动机部件。 舷外马达具有包括空气感应装置并且封装在罩内的发动机。 整流罩组件限定了封闭的空腔,发动机容纳在其中并且具有进气系统。 进气管道结构将空气引入空腔。 进气管道结构包括多个相对窄的连接通道,并且具有设置在通道的下游侧的膨胀室部分。 通过这种结构减少进气噪声。 在一个优选形式中,整流罩组件另外具有第二进气系统。 一个或多个连接通道与第一进气系统和第二进气系统连通。
