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.
