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.

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： An intake system of an outboard motor including a vertically arranged V-type engine comprises, an intake manifold connected to the intake ports, a surge tank connected to the intake manifold and disposed at a rear side from a central portion of the engine, a throttle body provided with a throttle valve, a plurality of intake passages for high revolution operation of the engine. The intake passages for high revolution operation extend from the surge tank and are communicated with the intake manifold, and the intake passages for low/intermediate revolution operation extend from the surge tank and are joined with the intake passages for high revolution operation, respectively. Each of the intake passages for low/intermediate revolution operation has a length longer than that for high revolution operation. A valve open/close mechanism is also disposed for opening/closing all at once portions upstream side of the joined portions of both the intake passages of the engine.
