Alarms of the Multi-Function Gauge
In addition to the displays noted above, the multi-function gauge
also displays several alarms. The following messages will be displayed if
an alarm occurs:
VOLT = Voltage falls below 11.5 volts. This message indicates
that the battery has discharged to an extent that may jeop-
ardize engine cranking and starting if action is not taken.
Start the engine to at least idle, and allow the battery to
re-charge.
OIL =
Oil pressure is below 4 p.s.i. when the RPM is below
1000 RPM or the oil pressure is below 10 p.s.i. and
above 1000 RPM. This message will occur only when the
engine is running. Stop the engine and check the oil level as
soon as this can be safely done.
TEMP = High engine temperature alarm. This message will oc-
cur only when the engine is running. If the engine does
not automatically reduce speed to the “limp home” level,
manually reduce speed and return to the dock as soon as
this can be safely done. It may be necessary to shut down
the engine and seek a tow to the dock.
TRAN = Transmission alarm.This message will occur only when
the engine is running. Stop the engine and check the trans-
mission oil level as soon as this can be safely done.
While air temperature readings are an optional addition to the
gauge, the lake temperature reading is standard on the gauge. This
comes from the paddle wheel located under the boat. If the sensor
becomes open or shorts out in the line to the battery, it will read 32
degrees F. If the sensor is shorted to the ground wire, it will read 150
degrees F. The SELF TEST feature of the multi-function gauge is located
on the lake temperature gauge. With the lake temperature displayed,
hold down the gauge selection display button for three (3) seconds or
until the self test has started. During the self-test, all the segments on
the display will light up. Also during the self test, the gauges will re-set,
go to mid-scale and then to full-scale. After two (2) sweeps the system
will return to normal.
Navigation/Anchor Lights
Switch
(All Models)
A three-position switch serves to activate
exterior lighting. Turning the switch in the up
position will activate bow and stern lights,
the middle position is OFF, and the down
position is for stern-only lighting.
Other Alarms
(All Models)
Sensors check the oil pressure, engine and transmission tempera-
tures. If the system detects readings outside the acceptable range, the
system shuts off the stereo and sounds the alarm for a period of one
(1) minute. This signals the need to return to shore as soon as pos
-
sible and seek assistance from your authorized MasterCraft dealer’s
service department to diagnose and, if necessary, repair the problem.
Refrigerator Switch
(MariStar 280, X-80, CSX 265, X-65)
This switch will run the refrigerator when turned
ON. The refrigerator runs off the boat’s electrical
and battery system. Therefore, care should be given to ensure that
the battery is not drained to such an extent that the voltmeter
alarm sounds.
Seat Heat Switches
(Optional All Models for Driver’s Seat;
Certain Models for Observer’s Seat)
A two-position switch allows heat to be
turned ON for the driver’s seat. In some
models, an optional observer seat heat switch is available and will be
found on the deck below the observer seat cushion. Note that this
swith will operate only when the ignition is in the ON position.
Shift/rottle Control
(All Models)
With the exception of the MariStar 280,
X-80 and CSX-265, a one-hand, single-lever
control operates as both a gear shifter and
a throttle. The lever automatically locks in the
neutral position (straight up and down) for
safety. The lever can be moved from neutral
only by raising the lifter under the ball knob.
Shifting is accomplished by moving the lever
forward or backward. Center (straight up) is
neutral. Moving the lever forward engages the running gear; moving it
back from center puts the drive train into reverse.
Never attempt to shift without the engine running!
During regular warm-up of the engine, it is possible to temporar-
ily increase the engine RPMs without moving the boat. To accomplish
this, push in the button located at the bottom of the shift/throttle
lever with one hand and pull up the “umbrella” (aluminum surround
below the top of the knob). Move the lever to desired position and
then simultaneously release the button and umbrella. The engine will
run with increased RPMs and can be increased or decreased by mov-
ing the lever. Returning the handle to the neutral position (as shown
in illustration above) will bring the system back to neutral and reduce
the engine RPMs to pre-set levels.
This function should be done sparingly. Over-revving the engine for
any extended period can cause undue wear and tear on the engine. Avoid
advancing to wide-open-throttle and holding the RPMs at that level.
In the MariStar 280 and X-80 the boat is equipped with a four-le-
ver control. The port side lever closest to the driver is the port engine
shifter, which allows the boat to move forward when shifted forward,
and backward when shifted aft. The next lever is the starboard engine
shifter and performs the same function. If both engines are running
and the boat is moving, the shifters should be shifted together and in
the same direction. Doing otherwise can damage the system.
The next middle lever is the port engine throttle, which allows the
boat to feed fuel into the engine and operate in motion. Pushing forward
