Note:
The blower must op-
erate for a minimum of four
(4) minutes before starting
the engine at any time. The
blower must also be operated
during idle and slow-speed
running, but is not necessary
during cruising speed.
To prevent a possible explosion, operate the blow-
er for at least four (4) minutes before starting the
engine and always when at idle or slow-running
speed. Explosive gasoline and/or battery fumes
may be present in the engine compartment. Fail-
ure to operate the blower as instructed may cause
improper ventilation of the boat engine and bilge
areas, and fuel vapors can accumulate in this area,
causing a fire or explosion which may result in
death or serious injury!
Horn
The horn is sounded by way of a but-
ton on the instrument panel. Press-
ing the button emits a loud and rec-
ognizable noise.
Manual and Automatic
Bilge Pump Switch
The bilge pumps on all V-drive models will be in the
automatic mode when the ignition key is turned ON.
Some models may have
two (2) switches, one for
the forward bilge and one
for the aft. In these in-
stances, the switches will
be marked. The manual
and automatic bilge dis-
charge system is never
completely off. When in
the automatic (default) position, a sensor alerts the
system to discharge water from the bilge area. Boat op-
erators are advised to leave the switch in the automatic
position, unless there appears to be excess water in the
bilge. In that event, the bilge pump can be manually ac-
tivated by turning the bilge pump switch to the manual
ON position. Return the switch to the automatic position
when finished emptying the bilge. Leaving the switch in
2008 MasterCraft Owners Manual Page 5-8
manual mode can result in damage to the pump and
may not be covered by warranty!
Ballast Empty/Fill Switches
On boat models equipped
with a ballast system, a
sepa-
rate
three-position switch
will allow for the filling or
emptying of the ballast tanks
and/or bags.
Be aware that
the engine must operate at
1500 RPM during the fill and
empty processes.
Check en-
gine specifications for related
engine idle speed, which may
be too low for the empty/fill
operation to be properly ac-
complished; it is likely that the
boat will need to be in motion
during the filling and emptying
of the ballast system. Failure to increase engine RPM to
the required level may result in malfunction or permanent
damage to the ballast pumps that force the water through
the system. Such damage is not covered under your war-
ranty. The ballast controls vary in location by model, and
the operator should determine exact location prior to use.
The three-position switches are clearly marked; FILL, OFF
(in center), and EMPTY.
Accessory Switches
Instrument panels may be equipped with Accessory
Switches. In some instances, the indicator may be la-
beled with the name of the
accessory, such as “Heat-
er.” Accessory switches
are two-position switches.
Turning the switch upwards
will turn a connected ac-
cessory ON, while turning
it down will turn the acces-
sory OFF.
Instrument Panel Gauge
Backlighting Switch
A three-position switch allows the op-
erator to change the instrument panel
backlighting for the gauges. Pressing the
top of the switch will cause the lights to
brighten, the center position is OFF, and
pressing down will dim the lights.
