The following section contains a general description of the instrument panel. Please note that instrument panels
are installed by the boat builder and will vary depending on the model installed. Commonly, instrument panels
are equipped with a tachometer, temperature gauge, oil pressure gauge, voltmeter, instrument panel lighting
switch, and an ignition switch.
Instrument panels can also be supplemented with extra Volvo Penta instruments such as: synchronization tach-
ometers, fuel gauge, fresh water gauge, clock, speedometer, or rudder indicator.
The instrument panel and/or gauges depicted

Gauges
1. Tachometer—Shows the engine RPM. Multiply
this value by 100 or 1000 (depending on model)
for revolutions per minute. Integral "Hours run"
meter (optional and separately installed) displays
the engine's operating time in hours and tenths of
an hour.
2. Temperature Gauge—Indicates engine temper-
ature. Normal operating temperatures are listed
in the section entitled Technical Data.
3. Oil Pressure Gauge—Indicates the engine oil
pressure. Normal operating oil pressures are
listed in the section entitled Technical Data.
Lower oil pressure is normal and should be
expected at idle after a sustained cruise.
4. Voltmeter—Indicates the charge voltage from
the alternator which should normally be approxi-
mately 14 Volts. With the engine stopped and the
switch on, battery voltage is normally indicated as
12 Volts.
5. Instrument Lighting—Turns gauge lights on or
off (varies, depending on product manufacturer).
6. Ignition Switch—The ignition switch has three
positions (varies, depending on product manu-
facturer):
A Accessories: Power is provided to run
accessories. Ignition is OFF and engine
is OFF.
O The key can be inserted or removed.
I RUN: Ignition is ON and engine is OFF.
System voltage connected.
II START position (momentary). The
starter motor is engaged and starting the
engine.
NOTICE! For additional information, please read the
starting instructions in the section entitled Starting.
Volvo Penta ignition keys are marked with a code for
use when ordering extra keys. Record the code so that
replacement keys can be ordered. Keep the code in a
safe place where unauthorized persons do not have
access to it.
