A lower unit for a marine propulsion device includes a drive shaft housing having a lower end, a gearcase housing connected to the lower end of the drive shaft housing and having an interior wall defining an elongated cavity, the interior wall including a first surface portion transverse to the longitudinal axis of the elongated cavity and a second surface portion transverse to the longitudinal axis and spaced circumferentially from the first surface portion. A propeller shaft is located in and extends axially through the gearcase housing cavity, and a propeller is supported on the propeller shaft. A hollow bearing carrier member encircles the propeller shaft for rotatably supporting the propeller shaft inside the gearcase housing. The bearing carrier member is supported by the interior wall of the gearcase housing and carries a bearing rotatably engaging the propeller shaft. A pair of anchoring members are also provided for anchoring the bearing carrier member to the gearcase housing, one of the anchoring members including a radially outer portion engageable with the first surface portion and the other of the anchoring members including a radially outer portion engageable with the second surface portion. Bolts are provided for forcing second portions of the anchoring members toward the bearing carrier member and for causing engagement of the radially outer portions against the surface portions of the gearcase housing. |
