OLTMETER
The voltmeter gauge
indicates battery bank
voltage. Each engine
operating voltage will
range between 12.0 to
16.5 volts when the
alternator is charging.
Significantly higher or
lower readings indicate
a battery problem,
alternator ,malfunction or
heavy battery drain.

AUGE
The oil gauge is often
the best indicator of
engine problems or
difficulties. Maximum
pressure is controlled
by a preset valve in the
oil pump. Note the
reading which this
gauge records after the
break-in-period, as it is
the “norm” which can be
used as reference
during the life of the
engine. IF A COMPLETE LOSS OF OIL
PRESSURE OCCURS, TURN ENGINE OFF AT
ONCE. Continued running after loss of pressure
will cause engine damage. First, manually check
the oil level. If low oil level is not the cause, consult
your Sea Ray
® dealer. DO NOT RESTART THE
ENGINE UNTIL THE PROBLEM HAS BEEN
CORRECTED.
Slight fluctuations in gauge readings are not
uncommon during operation and may be due to the
characteristics of the lubricating oil. Greater
fluctuations should be investigated. The cause may
be a clogged oil filter element which should be
replaced with every oil change.

AUGE
The water temperature
gauge indicates
temperature of the
cooling water circulating
inside the engine. Your
engine is equipped with
a thermostat so a
predetermined engine
temperature should be
reached soon after
starting the engine and
maintained thereafter
while the engine is
running. Refer to your
Engine Operator’s
Manual for proper gauge
readings. If the temperature approaches above
normal on your gauge, shut down engine at
once.

registering to the slower engine. To synchronize
the engines, adjust the engine RPM with the
throttles until the needle is centered in the
gauge. The engine synchronizer is designed
to operate between 1500 RPM and Wide Open
Throttle (WOT). When engines are not under
load and running in neutral gear, they will tend
to surge and indicate out of synchronization
very easily.
REFER TO YOUR ENGINE OPERATOR’S
MANUAL FOR PROPER GAUGE READING.
