Abstract
A marine stern drive unit (1) includes a fluid passage disposed within a drive shaft housing (11) of cast construction. The fluid passage has a discharge outlet (23) which is connected to the lower inlet end (41) of a generally centrally disposed vertical water cavity (24) cored into the drive shaft housing casting. The connection is very simple between the outlet and inlet. In addition, the vertical water cavity (24) in the drive shaft housing casting (19) is connected to a horizontal water pocket (59) therein through an angular connector passage (67) which is formed in a manner so as to require drilling through only a single wall remote from the shift pocket. The angularities involved reduce the sharpness of fluid flow turns.
