DRIVING GEAR FOR SHIPPING

摘要

Two hydraulic cylinders, one on each side of the stern drive and disposed between the tilt housing and the dirigible unit, steer the latter on the axis of the vertical drive shaft. The tilt housing is carried by lateral trunnions rotatable in bearings of the transom mounting on a transverse axis generally passing near the center of the universal joint in the horizontal drive shaft which extends through the transom. A trim adjustment and power tilt cylinder is disposed between the tilt housing and the transom mounting. The dirigible unit is suspended by the vertical drive shaft from an upper gear housing which in turn is removably secured to the tilt housing. The vertical drive shaft is protected from thrust and impact stresses by a steering support tube constituting a part of the dirigible unit and surrounding the shaft within a sleeve of the upper gear housing.
