摘要： An outboard motor includes an exhaust passage, a catalyst member, and a water capture member. The exhaust passage includes a first passage, a second passage, a third passage, and a fourth passage. The first passage is connected to exhaust ports, extends in a vertical direction, and collects exhaust discharged from the exhaust ports. The second passage extends laterally from the first passage. The third passage is connected to the second passage, extends downward from the second passage, and is disposed on a side of cylinders of an engine. The fourth passage is connected to the third passage, is positioned below the engine, and guides the exhaust to below the engine. The fourth passage discharges exhaust to the outside via a propeller boss of a propeller. The catalyst member is disposed in the third passage. The water capture member is disposed downstream of the catalyst member in the third passage.

摘要： An outboard motor includes a cooling water passage that guides cooling water to cool an exhaust passage and a cylinder unit. A cooling water intake port draws external cooling water into the cooling water passage. A water pump draws cooling water into the cooling water intake port and supplies the cooling water to the cooling water passage. A thermostat is arranged in the cooling water passage downstream of the catalytic converter and the cylinder unit. A first bypass passage is connected to a first connecting section provided on the cooling water passage. The first connecting section is provided along the cooling water passage at a position farther downstream than the catalytic converter and farther upstream than the thermostat.
