Troubleshooting
The bilge system is among the most important systems in the
boat. Attention should always be paid to proper operation.
• If the boat does not automatically pump water out of the system
when the ignition key is ON, verify that the bilge switch is set to
automatic.
• If it is set to automatic but still is not pumping when there is
evidence of water in the bilge, turn the pumps on manually using
the on-screen button. Follow the instructions above and do not
leave the switch turned to manual after water is evacuated.
• If the bilge pump(s) still does not work when turned to manual,
check the circuit breaker panel to ensure that electricity is
moving between the switch and the pump. If the circuit breaker,
which is marked, has tripped, reset it to ON.
• If the bilge pump(s) still does not work, it may be evidence of
debris in the system or failure of the pump’s impeller, which
must be replaced on a regular basis as detailed in the Care
and Maintenance section of this Owner’s Manual. This is a
serious concern. The bilge system keeps the boat from filling
with excess water that may cause imbalance in the boat’s
trim. Under the worst possible conditions, the boat can sink.
If the system fails while on a body of water, return to shore
IMMEDIATELY! Have all people on-board put on PFDs (personal
flotation devices). Signal for emergency help. If persons on-
board have working cell phones, contact help. After returning
to shore, take the boat to an authorized MasterCraft dealer as
soon as possible for repairs and do not use the boat again until
it has been properly repaired.
An inoperable bilge system can result in the boat taking on
excessive amounts of water, resulting in significant damage
to the boat, even sinking. Persons on board should wear PFDs
and be prepared to abandon ship if the boat is on an outing.
Operators should signal for emergency help and return to shore
IMMEDIATELY and have the boat repaired. Failure to follow
instructions can result in serious injury or death.
UNDERWATER EXHAUST
Models
The underwater exhaust system is a standard feature on X Series
and X Star models.
Purpose
By sending exhaust directly into the water, this feature
significantly reduces the amount of noise generated by the boat’s
inboard exhaust system. As a result, passengers can enjoy music
and hold conversations without having to raise their voices over
the sound of the exhaust system. The feature also reduces engine
backflow, heightening engine reliability and performance.
