The helm controls consist of three systems: the en-
gine throttle and shift controls, the steering system,
and the trim tab control switches. These systems
provide the operator with the ability to control the
direction and attitude of the boat from the helm
station.
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.
4 . 2 E ngine Throttle & S hif t C ontrols
The shift and throttle controls on your boat may vary
depending on the engine and options selected. The
following description is typical of most cable and
electronic control systems. Refer to the engine or
control manual for specic information on the con-
trols installed on your Boat.
Cable Engine Controls
Cable engine throttle and shift control systems con-
sists of three major components: the control handle,
the throttle cable and the shift cable. The cables are
all the push-pull type. Two cables are required for
each engine and control. One connects the remote
throttle control to the engine and the other connects
the remote shift control to the shift linkage.
The helm is designed for a binnacle mount control
with a single lever for each engine that operates as
a gear shift and a throttle. General operation will
include a position for neutral (straight up and down),
a forward position (the 1st detent forward of neutral),
and a reverse position (the 1st detent aft of neutral).
Advancing the control lever beyond the shift range
advances the throttle in forward or reverse. 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.
Electronic Engine Controls
Electronic engine controls are standard on some
engines and optional on others. The following con-
trol description is typical of most electronic control
installations.

HELM CONTROL SYSTEMS
Mercury Electronic Controls
The helm is designed for a binnacle style control
with a single lever for each engine. The electronic
control system consists of three major components:
the electronic control head, instruments and keypad,
control processors and applicable harnesses. The
controls are completely electronic and there are no
cables.
The controls have a single lever for each engine
that operates as a gearshift and a throttle. General
operation will include a position for neutral (straight
up and down or slightly aft of vertical), a forward
position (the 1st detent forward of neutral), and
a reverse position (the 1st detent aft of neutral).
Advancing the control lever beyond the shift range
advances the throttle in forward or reverse. Each
control is equipped with a means of permitting the
