ABSTRACT:
An engine E of an outboard motor O includes a carburettor 29 at an upstream end of an intake manifold 28, and an air intake 30 is detachably fixed to the carburettor 29 by two bolts 44. A cylinder block 21 of the engine E and a coupling portion 30-2 of the air intake 30 are interconnected through blow-by gas passages 40 and 41 with an oil separating chamber 39 interposed therebetween. The coupling portion 30-2 is provided at a location offset upwardly from axes of the two bolts 44. Therefore, both of the operation of the bolts 44 for attaching and detaching the air intake 30 and the operation of attaching and detaching the blow-by gas passage 41 to and from the coupling portion 30-2 can be conducted without any hindrance.
