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 52 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.
REFER TO OWNER’S MANUAL PACKET FOR
INSTRUCTIONS AND WARRANTY INFORMATION.

:
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.
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.

YNCHRONIZER
:
1. Both engines MUST be in the same throttle
position, running at the same rpm.
2. Turn ON “SYNC”switch located on the control
station switch panel (See Figure 3.6.1)
3. Both engines will adjust to the same rpm. The
master (port) throttle will control both engines.
Since the synchronizer is now controlling the
slave (starboard) engine, the lever is “limp” or
noneffective.
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.
