Abstract
A transmission for a marine propulsion device is provided with a movable member that responds to relative rotational movement between it and a driving shaft with an axial movement relative to the driving shaft and to a driven component. This axial movement is directed against one of two spring components which resist the axial movement. During the compression of either of the spring components, rotation of the driven component is non-synchronous with the driving component during a brief period of time. Also, the driven component is decoupled at least partially from torque transmitting relation with the driving component during the axial movement of the movable member relative to the driving and driven components.
