ABSTRACT:
In an outboard motor, an exhaust pipe coupled to a lower surface of a cylinder head of an engine extends downwardly through an oil case. An exhaust port, defined at a lower end of the exhaust pipe, is opened downwardly into an extension case. An exhaust gas sampling pipe, threadedly inserted into a seat surface formed on a lower surface of the extension case, extends upwardly into the exhaust pipe and has its inner end inserted into the exhaust port in the exhaust pipe. An outer end of the exhaust gas sampling pipe, extending out of the extension case, is closed by a detachable cap. Thus, it is easy to mount the exhaust gas sampling pipe for sampling an exhaust gas from the exhaust pipe for the outboard motor.
