Gauge Operation
Following is a general description of gauge operations. An alert skipper
monitors his gauges constantly for any system malfunctions. The gauges
are lighted for night operation. Gauges are an early warning system for
marine engines just as for automobiles. For more information, refer to
the engine manufacturer’s manual in the owner’s pouch.
Tachometer:
The tachometer indicates the speed of
the engine in revolutions per minute
(rpm). The tachometer allows you to
monitor the engine speed so you can
be sure not to exceed the
recommended limits of the engine
manufacturer. Selected tachometers
have built in hour meters.
The oil pressure gauge indicates the
pressure of the oil inside the gengine
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.
