ECTION
NOTE: Refer to your engine Owner's Manual to
operate the throttle arm by hand for maintenance.
!
WARNING
Shift selector(s) to NEUTRAL before starting engines.
Shift only when engine is at IDLE.
Reversing at high speeds can cause flooding/
swamping due to water being pushed over the
transom.
!
Shift quickly; easing into gear can damage the
transmission.
Hydraulic controls FORWARD and REVERSE
positions should always be in full travel extremes in
either direction for positive engagement and
minimum wear.
REFER TO OWNER'S MANUAL PACKET FOR
INSTRUCTIONS AND WARRANTY INFORMATION.

YNCHRONIZER
The engine synchronization feature is used to control
the speed of both engines, electronically, using one
throttle lever.
When the engine synchronizers are in operation, any
engine speed differential is immediately sensed and
automatically corrected. A single throttle movement
is all that is necessary to ensure that both engines
maintain identical RPM.
When the 44 DB is equipped with the standard
engines the sychronizer is turned on by the ENGINE
SYNC switch on the control station switch panel.
Optional engines come with the synchronizer
provided by that engine manufacturer. Refer to your
Owner's Manual Packet for correct synchronizer
operating instructions.

WARNING
Adjust both throttles to the same position before
turning the engine synchronization feature off. Failure
to do so can cause a sudden port or starboard turn.
2. Turn ON "ENGINE SYNC"switch located on
the control station switch panel (See Figure
2.10.1)
3. Both engines will adjust to the same rpm. The
master (starboard) throttle will control both
engines. Since the synchronizer is now
controlling the slave (port) engine, the lever is
"limp" or noneffective.

1. Both engines MUST be in the same throttle
position.
2. Put the "ENGINE SYNC" switch in the OFF
position. (Depress the bottom of the rocker-
switch)
The engines will slowly ramp to their physical throttle
settings.
!
WARNING
The engine synchronization feature must be turned
OFF before docking or low speed maneuvering, this
allows full and separate control of each engine. Failure
to turn off the engine synchronization feature can
cause personal injury, damage to the vessel, and/or
the dock.

The marine cruise control feature provides the
operator with fingertip control of predetermined
cruise speeds and the ability to increase or
decrease engine RPM in 25-rpm increments. The
control panel also displays critical engine information
(See figure 2.15.1).

feature is used to electronically control the speed
of both engines using one throttle lever.
