See full text

An outboard motor includes an exhaust passage that discharges exhaust gases generated in a V-type engine into water from an exhaust opening. The exhaust passage includes first and second branch passages connected to cylinders and disposed inside a V-shaped line, a first upstream collecting passage connected to each of the first branch passages, a second upstream collecting passage connected to each of the second branch passages, and a downstream collecting passage connected to the first and second upstream collecting passages. A portion from an upstream end of the downstream collecting passage to a downstream end of the downstream collecting passage is disposed outside cylinder heads of the V-type engine.
