b. The main pump, through the use of the controls on the control panel, provides the hydraulic power required to
turn the propeller. The piggyback mounted auxiliary pump provides power for steering, and for lifting the propeller out of
the water.
1-21. CONTROL PANEL AND CONTROLS.
a. The control panel is located on the port side of the propelling unit. The lift-tilt control valve on the lower-right
side to the control panel, and the forward-reverse control valve located on the left side of the control panel, are manually
operated. The tilt valve controls the kick-up of the outdrive assembly and the forward-reverse lever controls the propeller
speed in forward and reverse direction.
b. The steering wheel is connected to a power steering control unit. The steering control unit is fully fluid linked.
This means there is no mechanical connection between the steering unit, the pump and the steering motor. The unit
consists of a manually operated directional control valve and servo feedback meter element in a single body. The close
coupled, rotary action valve performs all necessary fluid directing functions with a small number of moving parts. The
manually actuated valve is coupled with the mechanical drive to the meter gear. The control is lubricated and protected
by the power fluid in the system and can operate in many environments. Power is directed through hydraulic hoses to
the steering motor located in the upper outdrive housing.
1-22. OUTDRIVE ASSEMBLY. The outdrive assembly receives hydraulic power, transmitted through hoses, and
performs all operating functions required to maneuver the watercraft. The lift-tilt is accomplished by transmitting fluid
power to the two hydraulic cylinders connecting the power unit and the outdrive assembly. The steering is controlled by
power transmitted to a hydraulic motor with a pinion geared output shaft. This pinion drives a large gear attached to the
column, which turns when hydraulic fluid is allowed to pass through the motor. The hydraulic power to turn the propeller
first passes through a swivel assembly in the upper housing. The fluid then flows through hoses to a hydraulic motor in
the thruster housing. The output shaft of the motor is coupled mechanically to the propeller shaft, which turns the
propeller.
