Cruising Speed
For best fuel economy operations at full 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 Engines.
If the engine does not reach its maximum throttle ran-
geit can depend on a number of factors mentioned in
the Fault Handling page 69
sedtion.
Select a propeller with greater pitch if actual enginer-
evolutions exceed the full throttle range. Contact your
Volvo Penta dealer for advice.
Triple installation
Since the center propulsion unit is installed in a tunnel
a slight efficiency loss for engine 2 is to be expected at
cruising speed and wide open throttle.
At cruising speed engine 2 will show slightly higher fuel
burn than engine 1 and 3. At wide open throttle engine
2 will run at a slightly lower RPM (-40–80 RPM) than
engine 1 and 3.
