in loss of control of the boat. This may lead
to serious injury or even death for those
on-board.
See Shift/Throttle Control informa-
tion elsewhere this section of the Own-
er’s Manual.
Operation:
The steering of a boat is very similar
to that of a car or truck, but it will gener-
ally respond less quickly due to opera-
tion in the water, which is more dense
than air. Read the Starting and Basic
Operations information and Operation-
al Hints that appear in the Preparation
section of this Owner’s Manual for more
detail and assistance.
Troubleshooting:
At any time, if the steering is slug-
gish, difcult, or shows any signs of
not working smoothly and properly, the
boat should immediately be taken to an
authorized MasterCraft dealer for atten-
tion.
The hydraulic steering system is not
accessible to the consumer for repair
or maintenance, all of which should be
done by an authorized MasterCraft deal-
er. Most of the standard steering system
repairs are also accessible only by the
dealer.
Water Jet Bow Thruster
Models:
Installed on X55, as option only.
Purpose:
A bow thruster allows for greater ma-
neuverability, especially in tight quarters
such as while docking the boat.
Location:
The port and starboard jets are lo-
cated near the bow, just under the water-
line. The water pump is remote-mounted
with the outlet plumbed to a “Y” valve
that diverts the water to each jet. The
thrusters are controlled by a joystick on
the driver’s armrest.
Operation:
When the joystick is moved left or
right, the bow of the boat moves port
or starboard respectively. The joystick
controls the “Y” valve, which (when
fully opened) to one side or the other,
energizes the electric water pump. The
thrust developed by the pump is diverted
by the “Y” valve to the opposite side,
causing the bow to move away from the
thrust.
Operate the thruster in pulses of a
few seconds or more. However, do not
operate for more than thirty (30) seconds
continuously at one time. Allow some
cooling time between periods of heavy
usage.
If the pump overheats, a thermal pro-
tector will shut down the pump for ap-
proximately ten (10) minutes to allow
the motor to cool. It then resets automat-
ically.
Troubleshooting:
1) If the joystick is unresponsive, check
that the bow thruster battery switch is
ON. If it is on, check the circuit breaker
box to be certain that it has not tripped.
2) If the pump runs when moving the joy-
stick, but no action results, check that the
inlet and outlet valves are open.
