Checking Instruments

Check instruments regularly. Stop the engine if there
is an abnormal reading or if the engine alarm sounds.

Oil Pressure

All engines have what is considered a normal operat-
ing oil pressure range. At engine idle this is normally
lower than at higher RPMs. For the normal operating
oil pressure range for your model engine, please refer
to the section entitled Technical Data on page 113.
Your boat is equipped with an audible low oil pressure

alarm .
CAUTION! If oil pressure is too low: Stop the
engine immediately and investigate. Operat-
ing the engine with oil pressure too low will
damage the engine.

Engine Coolant Temperature

All engines have what is considered a normal operat-
ing temperature range. At engine idle this is normally
lower than at higher RPMs. Normal operating temper-
ature for all engines (except 8.1 Gi & GXi) is 155°-
178°F (68°-81°C) and 135°-158°F (57°-70°C) for the
8.1 Gi & GXi. Engines with closed cooling systems will
typically run about 30°F (17°C) higher.
Your engine is equipped with an engine coolant and
exhaust temperature acoustic alarm
CAUTION! If engine coolant or exhaust tem-
perature is too high: Idle the engine, shift to
reverse and then to forward. Idle the engine
for 2 - 3 minutes and shut off the engine if the
temperature does not decrease. Investigate
and correct the malfunction. Operating an en-
gine with temperatures too high will damage
the engine.

Voltage/Charge

The operating charge is approximately 14 V. When
the engine is stopped and ignition is on, battery volt-
age is approximately 12 V. With the ignition turned off,
the voltmeter will not register a charge.
1. While Volvo Penta provides an audible alarm with every
engine, its installation is determined by the manufacturer
of your boat. If your boat does not have an audible alarm
available, we strongly recommend that you contact your
dealer to have one installed.
