Abstract
An outboard motor that significantly reduces or prevents discoloration around an exhaust hole includes an engine, a drive shaft, a propeller shaft, a housing, a discharge passage, and non-metal covers. The housing includes a discharge outlet to discharge an exhaust gas of the engine and the cooling water of the engine.

The covers are detachably attached to the housing so as to cover the discharge outlet and include at least one exhaust opening.
