2016 OWNERS MANUAL / 0235
Troubleshooting
•  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.
•  If the pump runs when moving the joystick, but no action results, 
check that the inlet and outlet valves are open.
•  If the joystick, pump and valves are all operational but there is 
still no action, check to be certain there is no debris  in the inlet 
screen.
•  If the bow thruster still is not operating properly, take the boat to 
an authorized MasterCraft dealer because other potential solu-
tions are in areas of the boat not accessible to the consumer. 
 
ZINC ANODE
Models
All except ProStar, as part of the Salt Water Package option.
Purpose
If the boat is operated in salt, polluted or brackish waters, even tem-
porarily, the boat should be equipped with a transom-mounted zinc 
anode to prevent  damage to those metal parts coming in contact 
with the water.
The zinc is, by design, self-sacrificing. It is slowly eroded away by 
electrolytic action and requires periodic inspection for deterioration. 
When the zinc has eroded to approximately one-half (1/2) of its 
original size, it must be replaced to continue protection, or damage 
to other metal parts may result.
Location
The anode is mounted on the transom.
Operation
There is no operation required. Boat owners should periodically 
examine the anode to determine how much erosion has occurred 
and consult an authorized MasterCraft dealer to determine the 
appropriate time to replace it.
