Instrumentation The instrument panel for Volvo Penta petrol engines is equipped with a tachometer, temperature gauge, oil pressure gauge, voltmeter, 2 fuses, instrument lighting switch and an ignition switch. Instruments, fuses and ignition switch can also be installed separately without an instrument panel. The boat builder’s instrumentation can also be supplemented with extra Volvo Penta instruments, such as: synchronization tachometers, fuel gauge, fresh water gauge, clock, speed log or rudder indicator.

Engine speed range: See chapter Operation.
2. Temperature gauge Indicates the engine coolant temperature. Normal operating temperature is approx. 70-90°C (158 194°F).
3. Oil pressure gauge Indicates the oil pressure in the engine. Normal operating oil pressure is approx. 150-500 kPa (21-71 psi). At engine idle this is normally lower.
4. Voltmeter 4

Indicates the charge current from the generator which should normally be approx. 14 V. With the engine stopped the current indicated is that in the starter battery circuit, normally 12 V.
5. Instrument lighting Switch for instrument lighting.
