Do not continue to run the engine if the
oil pressure is low. If you do, the engine
may 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 appro-
priate amount of approved motor oil before operating again or have your
boat serviced by your local authorized dealer’s service department. Note
that damage to your engine from inappropriate oil levels can be costly to
repair. Such damage is not covered by your warranty.
Fuel Gauge
(All Models)
Fuel gauge readings are only approximate. This
gauge is activated with the ignition switch. The rocking
motion of the boat during normal operation will cause
the fuel gauge to fluctuate. For a more accurate read-
ing, make sure that the boat is level and there is little
or no motion present. A red warning light will appear at
the bottom of the gauge when fuel is low.
MasterCraft recommends that operators do not run
the boat below a quarter of a tank, except as necessary
to return to shore, and not until the boat has been operated enough times to develop an
understanding of how the fuel gauge readings relate to the visual inspection of fuel left
in the tank. Extending fuel usage beyond the known capability of the boat may cause the
boat to run out of fuel and may leave you stranded o-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
small amount of water and debris that unavoidably accumulate in the bottom of the tank.
Rather than relying on visual inspection, you should pay attention to the fuel gauge.
Further, it is not recommended to allow the fuel to fall below one-quarter of a tank
full at any time as it may result in damage to the fueling system. (See the Fueling
section of this Owner’s Manual.)
Allowing the fuel level in the fuel tank to
fall below one-quarter of a tank full may af-
fect the reliability of the fuel pump or result
in damage to the fuel pump, which is not
covered under warranty.
Low Voltage Battery Alarm
(All Models)
In the event that the stereo has been functioning when the boat is not ON and running,
the voltage drain on the battery (or batteries) may result in diculties with re-starting the
boat. It may also cause intermittent erroneous or fluctuating gauge readings. When the
voltage level reaches 10.5 volts or below, the system will shut o the stereo and sound the
alarm.Generally,theappropriateactionistoleavethestereoOFF,aswellasdisengaging
any other peripheral electrical components, and keying ON the engine. Running the engine
at a moderate rate for several minutes without the additional drain of stereo and unnec-
essary electrical equipment will allow the alternator to recharge the battery or batteries,
unless the battery(ies) have been used to the extent of their life span.
Carbon monoxide is emitted from the en-
gine’s exhaust system. Never run the engine
without proper ventilation. Do not run the en-
gine in a confined space or where fumes may
be trapped. Do not run the engine when the
boat is stationary in calm wind conditions.
