Abstract
In a marine transmission, trailing faces of each of a plurality of gear projections extending axially from a forward gear are provided with a rake angle. This rake angle of each trailing face cooperates with an associated surface of each of a plurality of clutch projections to retain a dog clutch in an axial position relative to the forward gear even during periods when a marine vessel is rapidly decelerating and, as a result, the dog clutch moves into driving relation with the forward gear.
