Specifications

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 attention 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 circuit 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 temperatures 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
engine. 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 immedi-
ately 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 dam-
aged. 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,
ignition 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 immedi-
ate service.
Notice: If you continue to operate your boat with this
light on, you could adversely affect the emission control
systems 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
activity necessary to operate your boat. If
the battery is low or non-functional, or if
various 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.
OTHER ALARMS
Sensors check the oil pressure, engine and transmission
temperatures. If the system detects readings outside the
acceptable range, the system shuts off the stereo (if ON) and
sounds the alarm for a period of one minute. Even after the
alarm ceases, the Check Engine light will remain on.
This signals the need to return to shore and seek
assistance from your dealer as soon as possible to diag-
nose and, if necessary, repair the issue.
