GAUGE OPERATION
Tachometer
The tachometer (tach)
indicates the speed of
the engine in revolutions
per minute (rpm). The
tachometer allows you to
monitor the engine
speed so you do not
exceed the recommended
limits of the engine
manufacturer. Some tachometers have built in hour
meters.
The oil pressure gauge
indicates the pressure of
the oil inside the engine
lubrication system. A
drop in oil pressure may
be an indication of a low
oil situation or a leak.
Continued operation of
the engines with low oil
pressure could lead to engine damage. Refer to appropriate
manufacturer’s engine manual for more information..
Oil Pressure
Temperature Gauge
The temperature gauge
monitors the cooling
system of the engine. A
sudden increase in the
temperature could be a
sign that the engine
cooling system is
malfunctioning. Shut
down the engine
immediately and investigate the problem. Consult your
engine manual for allowable limits.
Fuel Gauge
The fuel gauge indicates
the level of fuel inside
the fuel tanks. It is a
good idea to keep the
fuel tanks “topped off ”
when possible to reduce
fuel vapors inside the
tank. Do not run the
fuel level close to empty.
Figure in an adequate “safety” factor when monitoring
fuel gauges since they are not entirely accurate.
Depth Gauge
The depth gauge
indicates the water
depth under the keel of
the boat. It features a
shallow water alarm. By
monitoring the water
depth closely, damage
related to props and
underwater hardware
can be avoided. See chapter 7 or the Faria owner’s manual
for detailed operational instructions.
Speedometer
The speedometer is used
on selected models
indicates kilometers per
hour and miles per hour
by measuring water
pressure against a small
hole in a device
mounted under the boat.
Consult the owner’s information packet on speedometer
maintenance.
