Transfer under way
1 To change helm station with the levers in forward
position, press the STATION button on the active
station. The pad lock goes out on all helm stations.
2 Activate the helm station that is to take control by
pressing the STATION button. The green LED will
light up and the N-LEDs (3) on the first station will
flash.
3 Move the levers on the control on the helm station
that have assumed control until they arrive at the
position of the levers on the first station. The station
will not be active until the levers are synchronized
with engine speed and gear.
4 If the levers do not correspond while the N-LEDs
led are flashing, the transfer will be interrupted and
the gear will move to neutral, the engine idles.
Levers must be in neutral position to gain control.
Cruising Speed
For best fuel economy operations at full speed must be
avoided. We recommend a cruising speed that is at
least 10% below the maximum engine revolutions at
top speed (full throttle).
Depending on hull type, the choice of propeller, the
load and sea state etc., the maximum revolutions at
top speed may vary, but they should be within the full
throttle range; refer to Technical Data, page 137.
If the engine is unable to reach its maximum throttle
range, this may be due to a number of factors
mentioned in Fault Handling, page 75.
Select a propeller with greater pitch if actual engine
revolutions exceed the full throttle range. Contact your
Volvo Penta dealer for advice.
Synchronizing Engine Speed
When driving with twin engines, both the operating
economy and comfort will be increased when the
engines are operating at the same engine speed (rpm).
When the synchronization function is activated, the
engine speed (rpm) of the starboard engine is
automatically adjusted to that of the port engine. The
synchronization function is activated automatically if
the following conditions are met.
1 The engine speed levers for both engines are in
(approximately) the same position.
2 The engine speed levers are in a forward position.
The synchronizer is disengaged as soon as the
conditions are no longer met or if the engines reach
maximum throttle.
