Abstract
A lower unit for a marine propulsion device comprises a housing having a central bore extending along a longitudinal axis, wherein the central bore at least partially defines an exhaust passageway for travel of exhaust gas from upstream to downstream through the lower unit. A bearing carrier is seated within the central bore and the bearing carrier further defines a portion of the exhaust passageway. A propeller shaft extends along the longitudinal axis and is coaxially supported within the bearing carrier. The lower unit includes an adapter having a convexly curved surface configured to cover an upstream-facing surface of the bearing carrier so as to smooth flow of the exhaust gas into the portion of the exhaust passageway defined by the bearing carrier.
