Quicksilver 555OP — System & Component Overview and Operation
Hydraulic Steering

6. Engine Control

Your boat comes with a mechanical gear shift/throttle control unit, located to the starboard of the
steering wheel, which activates both the shifting and throttle for the engine.
To start the engine, the control unit must be in the NEUTRAL position. When in neutral, the engine is
running, but the propeller is not spinning. There is a throttle only button that when pressed, will allow
you to operate the throttle without the propeller spinning. On the mechanical shift controller, the
button is located at the center of the throttle control, and when moved back to the center position,
the button will automatically re-engage the shifting mechanism.
Power Trim & Tilt
The power trim, located on the side of the gear shift throttle handle, allows you to raise and lower the
engine for trailering and launching the boat. It also allows you to adjust the engine to create the
optimum run angle for the boat to achieve best all around performance (fuel consumption, speed).
Refer to the engine manufacturer's manual for complete instructions, information and warranty.
