Abstract
An exhaust pipe extending from an engine of an outboard motor is covered with an exhaust pipe cover that defines a cooling water passage around an outer periphery of the pipe. An exhaust gas sampling pipe has a base end inserted into the exhaust pipe through the exhaust pipe cover, and a tip end occluded by a detachable plug. The exhaust gas sampling pipe and the plug are accommodated within an engine cover detachably mounted on an upper portion of an undercase, whereby it is protected against rusting due to the deposition of seawater and damaging due to collision against another object.
