2005 MASTERCRAFT OWNERS MANUAL–PAG E 6-2
FUEL GAUGE
The readings are only approximate. The gauge is
activated with the ignition switch. Rocking motion
of the boat during normal operation will cause fluc-
tuation of the fuel gauge. For a more accurate read-
ing, make sure that the boat is level and at rest.
When the boat is placed into initial operation, do
not run the boat below a quarter of a tank until you have re-
fueled several times and a have sense of how long you can
operate the boat on the fuel available. Extending usage beyond
the known capability may cause the boat to run out of fuel and
strand you away from the shore.
Although it may be possible to see fuel in the bottom of the
fuel tank, you still may not be able to operate the boat. The fuel
pick-up system was designed to avoid introducing the water
and debris that inevitably accumulate in the bottom of the tank.
Rather than relying on visual inspection, you should pay at-
tention to the fuel gauge.
TEMPERATURE GAUGE
The temperature gauge indicates the cooling
water temperature inside the engine as measured
in degrees Fahrenheit.
The normal operating temperature will range
from 140 degrees to 190 degrees. Engines with
electronic fuel injection also have a control cir-
cuit inside the engine control module that will cause the engine
to run at reduced speeds if the module senses that the engine is
running too hot. If you notice that your speed has reduced
during normal operation without reducing the throttle, monitor
your temperature gauge. If the gauge indicates excessive tem-
peratures during operation, slow down immediately and turn
off the ignition. This indicates an engine problem that needs
to be checked by the dealer!
Continuing to operate the boat while the temperature is
above normal operating parameters may cause serious damage
to your engine. Damage to your engine resulting from operating
the engine in an overheated condition can be costly to repair.
Such damage is not covered by your warranty!
ENGINE OIL PRESSURE GAUGE
The engine oil pressure gauge indicates the
pressure of the lubricating oil inside the en-
gine. The average pressure ranges are between
6 pounds-per-square-inch (PSI) at 1000 RPM
to 40 PSI or more at cruise-range speeds. A
reading of pressure below 5 PSI at 1000 RPM
may be caused by a low oil level or other potentially serious
problems that result in low oil pressure. If you experience
low oil pressure, stop your engine immediately and check
your oil level before operating again.
Do not continue to run the engine if the oil pressure
is low. If you do, the engine can become so hot that
it–or surrounding components–could catch fire.
You or others could be burned and the boat seriously
damaged. Check your oil level and add an appropriate
amount of approved motor oil before operating
again or have your boat serviced by your local MasterCraft
dealer. Note that damage to your engine from neglected
oil problems can be costly to repair. Such damage is
not covered by your warranty.
CHECK ENGINE LIGHT
The red malfunction indicator Check Engine
light is operated from an on-board computer
that monitors the operation of your fuel, igni-
tion and engine control systems.
On some models, the Check Engine light
should come on when the key is in the ON
position and the engine is not running. This is a check to show
you that it is working. If it does not come on at all, have it
repaired by your MasterCraft dealer right away.
If it stays on–or comes on while you are operating your boat–
the computer is indicating that you have a problem. You should
take your boat to your MasterCraft dealer for immediate service.
Notice: If you continue to operate your boat with this
light on, you could adversely affect the emission control sys-
tems on the engine. You could also experience poor fuel
economy, and your engine may not run as smoothly. This
could lead to costly repairs not covered by your warranty.
VOLTMETER
The voltmeter registers the electrical ac-
tivity necessary to operate your boat. If the
battery is low or non-functional, or if vari-
ous electrical items on the boat, such as
stereo equipment, is draining the battery
and impacting the boat’s ability to function
properly, the voltmeter will likely be the first
gauge to indicate that an issue is occuring.
LOW VOLTAGE BATTERY ALARM
In the event that the stereo has been functioning when the
boat is not ON and running, the voltage drain on the battery
can result in difficulties in re-starting the boat. It can also cause
intermitten erroneous or fluctuating gauge readings. To avoid
this situation, when the voltage level reaches 11.5 volts, the
system will shut off the stereo system and sound the alarm for
a period of two minutes to give boaters ample time to adjust.
