2-11.1 Synchronization Types
The following types of synchronization use the same criteria,
indications, and are turned ON and OFF as described in follow-
ing Sections.
2-11.1.1 Equal Throttle Synchronization (Twin Screw) (default)
Equal Throttle synchronization simply commands the same
throttle to both engines (i.e. push-pull cables travel the
same distance; electronic signals are the same). With
Equal Throttle Synchronization the Processors do not
receive tachometer signals representative of the engines
RPM's.
2-11.1.2 Active Synchronization (Twin Screw)(default Disabled)
Active Synchronization must be enabled during Set Up and
a Tach Sensor Wire Harness must be used.
The Processors each receive a tachometer signal represent-
ing engine RPM from their respective engines. These sig-

CAUTION: The Control System will remain synchronized as long as the Control Head's
levers are in close proximity to one another. If a lever is moved to a point
where the 10% throttle window is exceeded, a 10% increase or decrease in
engine RPM would occur with one engine, resulting in a sudden change in
the vessel's direction.
