Abstract
A method of changing the direction of rotation of an internal combustion engine, and in particular of a marine engine, in which the camshafts (15) include two cams (16, 17) for each tappet (20) of a controlled member, each of said cams being suitable for use in one direction of rotation, the direction of rotation of the engine being changed by shifting said camshafts in translation, wherein, prior to shifting said camshafts, the tappets are rotated through one-fourth of a turn so as to put the axis of rotation of each tappet cam-follower wheel (10) orthogonal to the direction of camshaft translation. The invention also applies to an engine employing the method.
