Disclosed herein is an outboard motor including a propulsion unit including an internal combustion engine having an exhaust port and an exhaust gas discharge system including a catalytic converter comprising a housing having an outer wall defining an axis, an inlet end with an inlet, and an outlet end with an outlet, a catalytic element located in the housing concentrically with the axis and having an outer surface defining, with the housing outer wall, an outlet volume which increases in size in the direction toward the housing outlet end, an inner surface spaced from the outer surface, defining therein an inlet volume, and defining, adjacent the housing outlet end, a by-pass opening communicating between the inlet volume and the housing outlet, and flow passages extending radially outwardly from the inner surface to the outer surface, communicating, at the inner surface, with the inlet volume, and communicating, at the outer surface, with the outlet volume, and a deflector moveable between a blocking position closing the by-pass opening and a by-pass position spaced from the by-pass opening and allowing flow therethrough from the inlet volume to the housing outlet.

[ We claim:] [1.] A catalytic converter comprising a housing having an outer wall defining an axis, an inlet end with an inlet, and an outlet end with an outlet, a catalytic element located in said housing concentrically with said axis and having an outer surface defining, with said outer wall of said housing, an outlet volume which increases in size in the direction toward said outlet end of said housing, an inner surface spaced from said outer surface, defining therein adjacent said housing inlet end, an inlet volume, and defining, adjacent said housing outlet end, a by-pass opening communicating between said inlet volume and said housing outlet, and flow passages extending radially outwardly from said inner surface to said outer surface, communicating, at said inner surface, with said inlet volume, and communicating, at said outer surface, with said outlet volume, a deflector moveable between a blocking position closing said by-pass opening and a by-pass position spaced from said by-pass opening and allowing flow therethrough from said inlet volume to said housing outlet, said deflector being imperforate and conical in shape and extending into said inlet volume and having a smaller end adjacent said inlet end of said housing and a larger end adjacent said outlet end of said housing, and means for variably displacing said deflector between said blocking position and said by-pass position to variably permit flow from said inlet volume to said outlet.
