Troubleshooting
At any time, if steering is sluggish, difficult, or shows any signs of
not working properly and smoothly, the boat should immediately be
taken to an authorized MasterCraft dealer for attention. The Dock-
Star Handling System is not accessible to the consumer for repair
or maintenance. All maintenance should be done by an authorized
MasterCraft dealer.
Always check your surroundings when using the DockStar Rudder
System in reverse, and never approach a person in the water in re-
verse. Always clear the area of downed riders or swimmers before
using the DockStar Rudder System in reverse.
PROPELLER(S) MAY CAUSE SERIOUS INJURY OR DEATH. Shut off
the engine(s) when near persons in the water, or on sunpads, swim
platforms or the boarding ladders.
WATER JET BOW THRUSTER
Models
Installed on X46 and X26, as an option.
Purpose
A bow thruster allows for greater maneuverability, especially in tight
quarters such as while docking the boat.
Location
The port and starboard jets are located near the bow, just under
the waterline. The water pump is remote-mounted with the outlet
plumbed to a “Y” valve that diverts the water to each jet. The thrust-
ers 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 protector will shut down the pump
for approximately ten (10) minutes to allow the motor to cool. It then
resets automatically.

Troubleshooting
At any time, if the steering is sluggish, difficult, or shows any signs
of not working smoothly and properly, the boat should immediately
be taken to an authorized MasterCraft dealer for attention.
Optional hydraulic steering components are not accessible to
consumers for repair or maintenance, all of which should be done by
an authorized MasterCraft dealer. Most standard steering system
repairs are only accessible by the dealer.
DOCKSTAR HANDLING SYSTEM
Models
Optional on select X Series, XT Series, NXT Series and XStar models.
Purpose
The DockStar Handling System controls the direction in which the
boat moves. The triple rudder system gives more control over
the boat than a traditional single rudder system alone. The Dock-
Star rudder allows a boat to reverse to either direction dependent
on the orientation of the steering wheel. A DockStar equipped boat
is also more agile and responsive at speed in forward.
Location
The DockStar Handling System is a triple rudder system mount-
ed to the bottom of the hull. Additional steering components are
mounted under the helm and under the engine in the engine com-
partment.
Operation
Steering a boat with the DockStar Handling System is very similar
to steering a car or truck, but the boat will generally respond slower
due to operation in the water, which is more dense than air. A Dock-
Star equipped boat will respond with more precision in forward at
both low and high speeds than a traditional inboard single rudder
system. In reverse, the DockStar system will allow the boat to re-
verse in either direction similar to a car. Like in a car, turn the wheel
to the left to back up to port, and turn the wheel to the right to back
to starboard
