Engine Speed Governing
The engine speed governor monitors the throttle position and the actual engine speed in order to help control the following items: engine speed, response, torque output and smoke limiting. The engine speed governor also helps to maintain constant engine speed.The engine speed is controlled by the governing of the fuel injection duration of the electronic unit injectors. Throttle input is used to calculate the desired engine speed.Engine Synchronization
Engine synchronization connects the Electronic Control Module (ECM) of the port engine and the ECM of the starboard engine to a common throttle. Engine synchronization increases the convenience of the operator and the control of the vessel. This feature is standard in marine applications.The engine synchronization enables either throttle to be used in a backup situation. The operator can use a switch to transfer the control of both engines to either the port throttle lever or starboard throttle lever. Refer to the Installation Guide for more information on engine synchronization.Engine and Marine Transmission Operation
Transmission Selector Lever
Power is transferred from the engine through the marine transmission to the propeller shaft. The marine transmissions can be operated by using one of the following methods:
Mechanical
Hydraulic
Pneumatic
ElectricalA control valve directs the flow of oil to the forward clutch or to the reverse clutch. The control valve is operated by a
