Abstract
A marine propeller shaft/key assembly in which a keyway formed in the shaft is provided with a perpendicular rounded forward end wall. The key, which transmits rotational forces between the propeller and the propeller shaft, is provided with a rounded perpendicular forward end which matingly engages the forward end of the keyway. The rounded perpendicular end of the keyway forms a stop which precludes axial forward movement of the key in the keyway.
