It is important to learn how to operate the engine, controls and other equipment safely and properly before setting
off on a maiden voyage. Avoid violent and unexpected changes in course and gear engagement. There is a risk
that someone aboard will fall over or overboard.
WARNING! A rotating propeller can cause serious injury. Check that nobody is in the water before engaging
ahead or astern. Never drive near bathers or in areas where people could be in the water.
Checking instruments
Check the instruments directly after starting the engine and then at
regular intervals while operating the boat. Normal readings during op-
eration:
Oil pressure: 150–500 kPa (engine warm)
At engine idle this reading is normally lower. The acoustic alarm will
automatically sound if the oil pressure is too low.
Engine coolant temperature (ECT): 75–90°C
The acoustic alarm will automatically sound if the engine coolant tem-
perature (ECT) is too high.
Charging: approximately 14 V
When the engine is stopped the voltage is approximately 12 V. The
acoustic alarm will automatically sound if the charging system mal-
functions.
Alarms and fault indications
When the acoustic alarm sounds one of the four warning lamps starts
to flash to indicate the source of the alarm. High engine coolant tem-
perature (ECT) (1), low oil pressure (2) and power-out (3).
IMPORTANT! In the event of a low oil pressure alarm: Stop the
engine immediately. Investigate and correct the malfunction.
In the event of a high engine coolant temperature alarm: Reduce
engine speed to idle (neutral). Stop the engine if the temperature
does not drop. Investigate and correct the malfunction.
If the diagnostics button starts to flash this indicates a malfunction in
the engine, controls or other fault (does not indicate a malfunction in oil
pressure or power-out). Press button in to obtain diagnostic trouble
code.
Note. Certain types of malfunction/fault will result in the engine speed
being automatically reduced by the electronic diesel control system.
Further information on fault-tracing, diagnostic trouble codes and
automatic reduction of engine speed (RPM) can be found in section:
Fault-tracing/Diagnostics.
