Abstract
The present invention, in one aspect, relates to a propeller shaft housing for being secured in the gear case bore and configured for being securely engaged to the gear case bore by threaded screws that pass through bosses in the housing and into threaded holes in the gear case. More specifically, in an exemplary embodiment, the propeller shaft housing includes at least two bosses having compound angle holes therethrough, and at least two threaded holes in the gear case are arranged to align with one of the respective holes through the bosses. Respective screws extend through the holes in the bosses of the propeller shaft housing and into threaded engagement with the threaded holes in the gear case. In the exemplary embodiment, one of the threaded holes in the gear case is adjacent a skeg, and one of the threaded holes is adjacent a strut. Specifically, the gear case includes a bullet, and a skeg extends generally downward from the bullet and a strut extends generally upward from the bullet when the engine is in an operative position.
