摘要

An outboard motor (1) includes a water-cooled V-engine (5). The engine includes right and left cylinder block portions (6R, 6L) each having plural cylinders (7) formed therein. The cylinders of each cylinder block portion are vertically juxtaposed. Cylinder heads (11, 11) are disposed behind the cylinder block portions. The outboard motor has horizontal and vertical shafts (3, 4). The outboard motor can tilt up on the horizontal shaft and pivot sideways on the vertical shaft. The cylinders of each cylinder block portion have a cooling jacket (33a) formed therein. The lowermost cylinder (6a) has a discharge portion (34) formed at an outermost part (6b) thereof. The discharge portion is designed to discharge out cooling water remaining in the cooling jacket.
