ABSTRACT:
An outboard engine includes a cylinder block having a breather passage, an opening provided sideways of and communicating with the breather passage, and a breather chamber disposed at the opening. The breather chamber is provided in a space defined between the cylinder block and an intake manifold positioned laterally of the cylinder block, and communicates with an intake air silencer chamber of the engine via a communication pipe. Making good use of the space, the breather chamber is disposed laterally of the cylinder block in the space, not axially of an engine cylinder as in a conventional arrangement, thereby reducing the axial length of the engine and making the latter compact.
