A flywheel housing is for a stern drive of a marine vessel. The flywheel housing comprises an inner mounting face for connection to an engine block of an internal combustion engine of the stern drive and an outer mounting face for connection to a gimbal housing. The inner mounting face and outer mounting face are on opposite axial sides of the flywheel housing. A conduit is formed in the flywheel housing and is configured to receive and discharge exhaust gases from the internal combustion engine. The conduit comprises an inlet port through which the exhaust gases are received from the internal combustion engine and an outlet port through which the exhaust gases are discharged from the flywheel housing.
