2021 OWNERS MANUAL / 236
Troubleshooting
At any time, if steering is sluggish, dicult, 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 o
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 X26, as an option.
Purpose
A bow thruster allows for greater maneuverability, especially in tight
quarters or 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 instrument panel or dash.
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. Do not
operate continuously for more than thirty (30) seconds 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.
