GAUGES
3-IN-1 GAUGE: FUEL GAUGE
Upper Half of Gauge
Fuel gauge readings are approximate. This
gauge is activated with the ignition switch.
The rocking motion of the boat during normal
operation will cause the fuel gauge to fluctu-
ate. For a more accurate reading, make sure
that the boat is level and there is little or no
motion present.
A “low fuel” notice will come up on the video screen as a warning to
return to shore and refuel. 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 remaining in the tank. Extend-
ing fuel usage beyond the known capability of the boat may cause
the boat to run out of fuel and may leave you stranded off-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 atten-
tion 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 affect the reliability of the fuel pump or result in
damage to the fuel pump, which is not covered under warranty.
3-IN-1 ENGINE OIL PRESSURE
GAUGE
Lower Right Side
The engine oil pressure gauge indicates
the pressure of the lubricating oil inside the
engine. The average pressure ranges are
between six (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, causing a red warning light to appear at the bottom of
the gauge.
