PURPOSE:To provide an exhaust device for an outboard motor engine in which required length of the whole of a passage can be secured without changing any vertical directional dimension of an exhaust passage while increase in a size of the engine can be prevented so as to comply with compactification of an outboard motor. CONSTITUTION:In construction of an exhaust device for outboard motor engine 6 in which an exhaust passage is vertically extended, an expansion chamber A is formed in the middle of the exhaust passage, and a catalyst 40 is arranged inside the expansion chamber A, while a folded part, 23, which is once extended upward from the expansion chamber A and then bent to be extended downward, is constructed. The folded part, 23 is bent in the width direction of a hull. The folded part 23 is positioned below a V-bank of the engine 6, and electrical equipment 28 is arranged above the V-bank. |
