Instrumentation 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 1 . 21194 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. 7743722 - Downloaded from www.volvopenta.com 13/05/2008 20:17:06 21195 Your engine is equipped with an engine coolant and exhaust temperature acoustic alarm 1 . 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. 21196 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.
