Cruising speed
Avoid operation at full throttle, for best fuel economy.
We recommend a cruising speed which is at least
10% below the maximum engine speed at full speed
(full throttle). The maximum engine speed will vary
due to propeller choice, load and sea conditions, but it
should be in the full throttle range.
Full throttle range:
D4 ......................................................3400–3600 rpm
D6 ......................................................3400–3600 rpm
If the engine does not reach the full throttle range,
this could be caused by a number of factors which are
noted in the “Fault tracing” chapter. If the engine speed
exceeds the full throttle range, select a coarser pitch
propeller. Ask your Volvo Penta dealer for advice.
Acknowledging alarms and
messages
There are several types of alarms and messages that
can appear as a pop-up in the tachometer/display.
NOTE! Some alarms for fault are also accompanied
by a buzzer. First silence the buzzer by pushing the
NAVIGATION WHEEL on the control panel.
1. Read the alarm/message pop-up.
2. Acknowledge the pop-up by pushing the NAV-
IGATION WHEEL on the control panel (sometimes
repeatedly). The pop-up will disappear.
3. Take the indicated actions.
If there is an alarm pop-up of a fault please refer to the
”In case of emergency” and “Fault register” chapters.
NOTE! If there is a fuel alarm pop-up it will reappear
every 10 minutes until tank is filled. If there is a depth
alarm pop-up it will reappear every 30 seconds until
the depth exceeds the depth alarm setpoint.
