5.7 Helm Controls
The helm controls allow you to engage the boat’s engines, control the
boat’s speed and engine RPMs, and control the direction in which the
boat is traveling.
5.7.1 Shift/Throttle Levers
Two shift/throttle levers allow you to both shift the engines from neutral
to forward or reverse and control the engine RPMs. With the levers in
the center position, the engines remain in neutral at their lowest RPM
levels. Lifting the levers above the neutral position shifts the engines to
forward and increases the RPM levels. Lowering the levers below the
neutral position shifts the engines to reverse and increases the RPM
levels.
The shift/throttle levers are located on the starboard side of the steering
wheel. The outboard lever controls the starboard engine and the inboard
lever controls the port engine. The engines can be shifted/throttled
independently to improve maneuverability in tight quarters.
Because your boat has dual engines, it is recommended that you operate
the engines at the same speed while cruising. This reduces engine noise
and vibration, and improves engine efficiency.
Use the engine synchronizer gauge to monitor the speed of each engine.
Adjust the shift/throttle levers so that the synchronizer gauge needle is
centered.
NOTE: Aligning the shift/throttle levers with each other does not neces-
sarily mean the engines are synchronized. To accurately synchronize the
engines, rely on the tachometers or the engine synchronizer gauge.
5.7.1.1 Engine Synchronizer
The engine synchronizer allows you to electronically and mechanically
interconnect both engine shift/throttle levers. This allows you to increase
and decrease engine speed using one lever, and keeps the engines pre-
cisely synchronized. Refer to the OEM information for details on operat-
ing the engine synchronizer.
5.7.1.2 Shift/Throttle - Engine Interface
The shift/throttle levers from both helms are connected to the engines by
an electronic control system. Refer to the OEM information for details on
adjusting and maintaining the shift/throttle control systems.
