The gear and throttle lever bodies are made of
anodized aluminum. To clean them, a warm soapy
water solution should be used. DO NOT use an
abrasive compound.
NOTE: Refer to your engine Owner’s Manual to
operate the throttle arm by hand for maintenance.
REFER TO OWNER’S MANUAL PACKET FOR
INSTRUCTIONS AND WARRANTY INFORMATION.

YNCHRONIZERS
(O
PTIONAL
)
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. The synchronizer control unit is located
on the aft component board in the bilge.
If you have this option, refer to your Owner’s Manual
Packet for the correct operating instructions for your yacht
engine synchronizers.
O
PERATION
:
1. Have both engines running and advance speed
slightly above idle.
2. Turn ON synchronizer switch located on the
control station switch panel.
3. Move slave (starboard) engine throttle lever to
maximum speed position. Since the
synchronizer is now controlling the slave
engine, the lever is “limp” or noneffective.
Advancing the slave engine lever eliminates the
synchronizer of undue strain in moving the entire
control system.

The trim tabs on your Sea Ray ® are operated with
a rocker type momentary switch at the control
station. They are protected by a circuit breaker on
the control station breaker panel (See Figure 6.6.2)
which must be ON to use the trim tabs .
To trim the bow of your boat down, push the top
halves of BOTH rockers down in momentary bursts.
If you hold the rockers down, you will over trim the
boat and the bow will dig in. To correct over-trimming,
push bottom halves of BOTH rockers to obtain
desired planing angle.
The trim tabs on the transom of your boat can also
be used to trim the list of your boat (See chart
above) that may be caused by improper storage of
gear, too many people on one side or a strong cross
wind. Operation of the rocker switch should be
momentary bursts to achieve proper attitude of the
hull.
