摘要： A boat propulsion system includes a drive bevel gear fixed on a lower end of a drive shaft, a forwarding bevel gear and a reversing bevel gear rotatably fitted on a propeller shaft and meshing together with the drive bevel gear, and a dog clutch mounted on the propeller shaft and rotatable with the propeller shaft, moves in an axial direction of the propeller shaft, and meshes together with the forwarding bevel gear or the reversing bevel gear to rotate the propeller shaft, in which the propeller shaft comes in contact with the forwarding bevel gear via a forwarding side buffer member having a disc spring as a component member. The boat propulsion system prevents and minimizes sound and impact even when variations in thrust force occur.

摘要： An exhaust system for an outboard motor includes an improved construction that can be compact enough for the limited space afforded within a powerhead of an outboard motor. The outboard motor includes an engine and a support member arranged to support the engine. The engine includes a cylinder block that defines a plurality of cylinder bores. The cylinder bores extend generally horizontally and spaced apart vertically from each other to form a cylinder bank extending generally vertically. At least two exhaust manifolds extend generally vertically aside and along the cylinder bank. Pistons reciprocate within the cylinder bores. A cylinder head closes ends of the cylinder bores to define combustion chambers together with the cylinder bores and the pistons. The cylinder head further defines at least one exhaust port per each one of the combustion chambers. Exhaust passages communicate with the exhaust ports. The exhaust passages are coupled with the exhaust manifolds so that at least one of the exhaust passages is allotted to each one of the exhaust manifolds.

摘要： An engine decompression device includes an improved construction to release at an exceedingly slow engine speed. The engine has a camshaft that actuates at least one exhaust valve and extends generally vertically. The decompression device has an actuator mounted on the camshaft for pivotal movement about a pivot axis extending generally normal to an axis of the camshaft. The actuator includes a cam section that holds the exhaust valve in an open position and a sinker section that moves with centrifugal force produced by relatively slow rotation of the camshaft so as to release the cam section from holding the exhaust valve open.
摘要翻译：发动机减压装置包括改进的结构，以非常缓慢的发动机速度释放。发动机具有致动至少一个排气阀并且大致垂直延伸的凸轮轴。减压装置具有安装在凸轮轴上的致动器，用于围绕大致垂直于凸轮轴的轴线延伸的枢转轴线枢转运动。致动器包括将排气阀保持在打开位置的凸轮部分和通过由凸轮轴相对较慢旋转产生的离心力移动的沉降片部分，以便释放凸轮部分以保持排气门打开。
