摘要： Exhaust passage system in an outboard engine unit includes: an engine-side exhaust pipe; a downstream exhaust pipe for directing exhaust gas downstream from the engine-side exhaust pipe, a lower end portion of the engine-side exhaust pipe and an upper end portion of the downstream exhaust pipe being positioned in horizontally parallel to each other and horizontally overlap each other so as to provide fluid communication therebetween via a through-hole formed in the overlapping portions of the end portions; and a vertical partition wall provided, in an upper end region of the overlapping portions for hampering back-flows of fluid.
