HELM CONTROL SYSTEMS
2.1 General
The helm controls consist of the throttle and shift controls, the steering system, the automatic fire extinguisher
system and the trim tab control switches. Optional equipment may include an engine synchronizer.
Each manufacturer of the control components provides an owner’s manual with its product. It is important
that you read the manuals and become familiar with the proper care and operation of the control systems.
2.2 Engine Throttle and Shift Controls
The shift and throttle controls on your boat may vary depending
on the engines used. The following control description is typical
of most inboard remote controls. Refer to the engine or control
manuals for specific information on the controls installed on
your Pursuit.
The helm is designed for a binnacle style engine throttle and shift
control system that typically consists of three major compo-
nents: the helm throttle and shift controls, the throttle cables and
the shift cables. Movement of the helm control lever pushes or
pulls a cable that operates the engine throttle or transmission
control. A typical twin engine inboard will have two throttle
controls and two transmission controls at each helm station.
Each control is equipped with a means of permitting the engine
to be operated at a higher than idle RPM while in neutral for cold
starting and warm-up purposes. Some boats may be equipped
with a cable throttle friction brake located on the throttle cable.
The friction brake may be required to overcome the return spring pressure on the fuel injector throttle lever
and prevent the throttle from creeping back.
During most operations of a twin engine boat, it is advantageous for both engines to be operated at the same
RPM. This reduces noise, and vibration, and can increase engine efficiency. Setting the throttles so that the
engines are running the same RPM (synchronized) can be done by listening to the engine sounds or with an
engine synchronizer. Attempting to synchronize the engines solely by using the tachometer readings or control
lever placement generally will not work. When the engines are in proper synchronization, the throttle levers
may not necessarily be even. Please refer to the engine or control manual for more information on the controls
installed on your boat.
