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.
A marine engine, comprising:
A method of mounting a propeller shaft housing in a lower unit drive housing of a marine propulsion unit, the propeller shaft housing having at least two bosses having holes therethrough, the lower unit heaving a gear case with compound angle threaded holes therein arranged to align with respective holes through the bosses, said gear ease also comprising a gear ease bore for receiving the propeller shaft housing said method comprising the steps of:
A kit for a marine engine having a gear ease and a bore therein, said kit comprising a propeller shaft housing for being secured in the gear case bore, said propeller shaft housing comprising at least two bosses having holes therethrough, at least on of said holes extending at a compound angle wherein said bosses are positioned on same side of a vertical centerline of the gear case.
A propeller shaft housing assembly for a marine engine, the marine engine including a lower unit having a gear case with a bore therein, said assembly comprising:
A propeller shaft housing assembly for a marine engine, the marine engine including a lower unit having a gear ease with a bore therein, a propeller shaft extending through the bore, said assembly comprising:
A marine engine, comprising:
A marine engine, comprising:
A propeller shaft housing assembly for a marine engine, the marine engine including a lower unit having a gear case with a bore therein, said assembly comprising:
A propeller shaft housing assembly for a marine engine, the marine engine including a lower unit having a gear case with a bore therein, said assembly comprising:
