摘要： A motor including an intake-side conduit member disposed outside a casing that makes a connection between a cooling water intake section of a water pump and an intake hole, and a cooling water relay section provided outside the casing. The cooling water relay section communicates with a cooling water supply passage in the casing. A discharge-side conduit member that is disposed outside the casing connects the cooling water relay section to a cooling water discharge section of the water pump. Additionally, the other end of a transmission cooling conduit member that is branched from the cooling water relay section is connected to a water jacket of the transmission. The conduit members are preferably flexible hose members, for example. Accordingly, this unique construction improves a cooling water piping layout around a water pump, a discharge performance of the water pump, and an assembly workability of a motor.

摘要： An outboard motor includes a transmission device disposed on a middle portion of a drive shaft driven by an engine. The transmission device includes a forward-reverse switching device housed in a transmission case. Lubricating oil for lubricating the forward-reverse switching device is stored in the transmission case. The transmission case has a drain hole arranged to discharge lubricating oil in the transmission case that is provided in a lower portion of a side wall and in a position in front of the drive shaft, and a drain bolt for opening or closing the drain hole. An exposed opening for exposing the drain hole is provided in an upper case that covers the transmission case. As a result, work efficiency in discharging or draining of lubricating oil is greatly improved without requiring dismantling of a main body of the outboard motor.

摘要： A power transmission system for a marine propulsion unit includes a case arranged to be supported on a hull; a propeller supported at the lower end portion of the case for rotation about an axis extending in a fore-and-aft direction; a transmission housed in the case and having an axis with planetary gear trains extending vertically to receive an output from an engine, and change the speed of the output prior to transmission thereof; and an interlocking device arranged to receive the output from the transmission and transmit the output to the propeller. A speed reduction device is arranged such that it is interposed between the transmission and the interlocking device, receives the output from the transmission, and decelerates the output to transmit it to the interlocking device. This arrangement reduces the weight of a transmission unit in a power transmission system of a marine propulsion unit and decreases an external size of the transmission unit.

摘要： An oil supply device includes an axial oil passage and an intersecting oil passage provided in a propeller shaft, an axial oil passage and an intersecting oil passage provided in a drive shaft, and an oil guide passage. The intersecting oil passages allow oil inside the axial oil passages to be spouted radially of the shaft by centrifugal force generated as the shafts rotate. The oil is then supplied via the oil guide passage to an intermediate speed reduction device. As a result, it is possible to sufficiently lubricate an intermediate speed reduction device mounted on a drive shaft through a simple and compact arrangement.
