Specifications
A.
Tachometer
The Tachometer indicates the speed of the engine
in
revolutions per minute. This speed is not the boat
speed nor necessarily the speed of the propeller. The
Tachometer may not register zero with the Ignition Key
in
the OFF position.
B.
Temperature
Gauge
The temperature gauge monitors the cooling system of
the engine. A sudden increase
in
the temperature cou
Id
be a signal of a blocked cooling passage or a water
pump malfunction.
C.
Oil
Pressure
Gauge
The Oil Pressure Gauge provides an indication of the
pressure
in
the engine lubrication system. A drop
in
oil
pressure
is
a possible indication of oil pump or leakage
problems.
D.
Voltmeter
The voltmeter monitors the battery condition. See Sec-
tion E for additional information on voltmeter operation.
E.
Fuel
Gauge
The Fuel Gauge displays the level of fuel that
is
present
in
the fuel tank(s). See section E for more detailed
information on fuel gauge operation.
F.
Power
Trim
Gauge
Boats equipped with MerCruiser Stern Drives also have
a "Power Trim Gauge." This gauge provides a visual
indication of the inward-outward position
of
the
outdrive. If the boat is equipped with a second control
station, an optional Power Trim Gauge can
be
added to
that station.
G.
Engine
Alarm
Systems
Engine alarm systems are installed on some models
with specific types of engines. The alarm
is
an audible
alarm that is mounted in the helm area;
it
is
actuated by
engine water temperature and engine oil pressure
senders. The alarm will sound in the event of low engine
oil pressure or high engine water temperature.
. The engine alarm will sound during engine startup, or
whenever the Ignition Switch
is
positioned to
ON
and
the engine is not operating. The alarm sounds under
these conditions because engine oil pressure
is
low; the
alarm will cease to sound as soon as engine oil pressure
rises to the proper level.
IMPORTANT: The engine alarm systems installed
in
these boats monitors only engine water temperature
and engine oil pressure. Always maintain a close visual
watch
on
the drive(s), transmission(s), engine fluid
levels, bilge water level, etc.
H.
Engine
Synchronizer
Most dual engine Carver models can be equipped with
an optional engine synchronizer. This instrument com-
pares the electrical signals generated by the. engines
and converts those signals to a visual meter indication
of engine speed difference. The meter movement
responds to changes in throttfe position. When the
needle
is
centered, the engines are
in
proper synchron-
ization. '
I.
Instrument
Maintenance
Electrical protection for instruments and ignition cir-
cuitry is provided by a fuse
or
cirucit breaker on the
instrument panel.
Periodically, spray the Ignition Switch(s) with a contact
cleaner/lubricant such as LPS,
CRCor
WD40. The
