摘要： A marine outboard motor (2) for a marine vessel (1) is provided. The marine outboard motor includes an internal combustion engine (100), a drive shaft (27) configured to transmit a drive force from the internal combustion engine, a propeller shaft (29), and a drive transmission configured to transmit the drive force from the drive shaft to the propeller shaft. The motor also includes a lubrication system configured to convey lubricant along a lubricant flow path to lubricate one or both of the drive transmission and the drive shaft, and a lubricant filter (83) provided along the lubricant flow path and configured to remove solid contaminants from the lubricant as it flows along the lubricant flow path. The lubricant filter is configured to be driven by the drive shaft.

摘要： A marine outboard motor (2) is provided with an internal combustion engine (100) comprising an engine block (110) defining at least one cylinder, an air intake (150) configured to deliver a flow of air to the at least one cylinder, a crankcase (140) in which a crankshaft (31) is mounted for rotation about a crankshaft axis (32) which is substantially vertical when the marine outboard is vertical, and a crankcase ventilation system (170) configured to vent blow-by gases from the crankcase and to supply vented blow-by gases to the air intake. The crankcase ventilation system comprises a lubricant separation chamber (180) for separating lubricant from the blow-by gases. The lubricant separation chamber is defined by the crankcase and extends along the length of the crankcase substantially parallel to the crankshaft axis.

摘要： There is provided a marine motor (2) having an internal combustion engine (100) having an engine block (110) with at least one cylinder, an air intake (120), an exhaust conduit (130) configured to direct a flow of exhaust gas from the at least one cylinder, and an exhaust gas recirculation system (140) configured to recirculate a portion of the flow of exhaust gas from the exhaust conduit to the air intake. The exhaust gas recirculation system (140) includes a first exhaust gas recirculation circuit (141) with at least one first EGR cooler (151) having a first overall conductance, and includes a second exhaust gas recirculation circuit (145) with at least one second EGR cooler (152) having a second overall conductance which is greater than the first overall conductance. The exhaust gas recirculation system (140) also includes flow control means (143, 147) configured to selectively vary the relative proportions of first and second flows of recirculated exhaust gas through the first and second exhaust gas recirculation circuits to allow the amount of exhaust gas cooling to be varied.

摘要： A marine outboard motor (2) is provided with a gear casing (40), a propeller shaft (29) rotatable within the gear casing about a propeller shaft axis (34), a drive shaft (27) having a drive gear (35), a clutch mechanism (50) for selectively engaging the drive gear with the propeller shaft and a shift mechanism (60) configured to operate the clutch mechanism. The shift mechanism comprises a support shaft (70) which is fixed relative to the gear casing and which extends along or parallel with the propeller shaft axis, a shift shuttle (80) which is slidable along the support shaft and is connected to a clutch member (53) of the clutch mechanism, a shift finger (90) pivotally mounted on the support shaft, and a shift rod (61) coupled to the shift finger by a releasable coupling. The shift finger is configured to move the shift shuttle along the support shaft to operate the clutch member when the shift finger is rotated about the shift rod axis by the shift rod. A marine vessel including such a marine outboard motor is also provided.
