摘要： A lubricating system for an outboard motor equipped with a vertical type engine. In one embodiment, the lubricating system has an oil pump positioned near the bottom of the engine, the oil pump driven by an oil pump rotor that is positioned at a connection between the crankshaft and an engine drive-shaft, the oil pump rotor being linked to the crankshaft. The system further includes a camshaft-driving mechanism for transmitting the rotation of the crankshaft to a propulsion device. The camshaft-driving mechanism is also positioned at the connection between the crankshaft and the drive-shaft and is also linked to the crankshaft. The lubrication system also has a main oil tank for storing lubricating oil circulated by the oil pump, and an engine-cooling water passageway positioned next to the main oil tank. Another element of this embodiment of the lubricating system is a filter-mounting base positioned on an outer wall of the cylinder blocks. The system also has oil passageways positioned at the bottom of the cylinder blocks for distributing the oil.

摘要： There is provided a lubricating structure for an outboard motor, which can secure a sufficiently large cross-sectional area for a main oil gallery while preventing an increase in the width of an engine thereof. A water-cooled four-cycle six-cylinder V-type engine having a generally vertically disposed crankshaft is mounted on an engine holder. A cylinder block is disposed at the rear of a crankcase disposed in the foremost end (i.e. on the bow side) of the engine, and a main oil gallery extends vertically in the starboard-side side part of the cylinder block. Namely, the main oil gallery is disposed not in a central part of the cylinder block in the transverse direction thereof, but at a location outward of cylinder bores of the cylinder block.
