34
If 2 control panels are installed at separate helms, never
operate the bow thruster from both panels simultaneously.
Do NOT test the bow thruster while the boat is out of the
water, unless you are certain that everyone is a safe
distance from the thrust tube.
Never allow the bow thruster to run for longer than 5
seconds with the boat is out of the water.
Bow Thruster Movement
Refer to the bow thruster owner’s manual for exact battery
requirements.
13. Steering
Your boat comes equipped with a hydraulic steering system. The basic system for a single engine boat
contains a steering wheel, a hydraulic helm pump, a hydraulic steering cylinder, and hydraulic hoses. If
you purchase a Mercury Verado® six cylinder engine, the steering system includes an electric power
assisted steering pump to aid in the handling of the vessel.
Operation
When turning the steering wheel, the helm pump forces hydraulic fluid through hoses to and from the
steering cylinder which is connected to the tiller arm on the engine. The cylinder moves the tiller arm
to either port and starboard, depending upon the direction the steering wheel is turned.
Maintenance
A hydraulic steering system rarely needs to be refilled after the system is bled. However, if you ever
need to add fluid to the system, refer to the steering manufacturer’s manual for complete instructions.
On a standard helm (non–L6 Verado), the fill is located on the top of the helm pump. On a six cylinder
