Abstract
Transmission, especially for boat motors, with a shift mechanism in which an amplification of the clutch force is achieved by threaded engagement of the gear-engaging sleeve with the associated shaft. The transmission has shock and oscillation absorbers built into the housing, comprising a pair of sets of cup springs which can be disposed between said shaft and the gears to provide limited axial displacement of the shaft relative to the gears against the force of the springs when the sleeve is rotated relative to the shaft.
