Checking Instruments; Oil Pressure; Engine Coolant Temperature; Voltage/Charge - Volvo 5.0OSiE-J Operator's Manual

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.

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 115.
Your boat is equipped with an audible low oil pressure

alarm .
NOTICE! If oil pressure is too low: Stop the engine
immediately and investigate. Operating the
engine with oil pressure too low will dam-
age 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 5.0–5.7L engines is 155°-178°F
(68°-81°C) and 135°-158°F (57°-70°C) for 8.1L en-
gines. Engines with closed cooling systems will typi-
cally run about 30°F (17°C) higher.
Your engine is equipped with an engine coolant and
exhaust temperature acoustic alarm
NOTICE! If engine coolant or exhaust temperature is
too high: Idle the engine, shift to reverse
and then to forward. Idle the engine for 2 to
3 minutes and shut off the engine if the tem-
perature does not decrease. Investigate
and correct the malfunction. Operating an
engine with temperatures too high will dam-
age the engine.

Voltage/Charge

The operating charge is approximately 14 V. When the
engine is stopped and ignition is on, battery voltage is
approximately 12 V. With the ignition turned off, the
voltmeter will not register a charge.
