HELM CONTROL SYSTEMS
2.1 General
The helm controls consist of three systems: the
engine 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.
2.2 Engine Throttle and Shift Controls
Your boat can be equipped with a single engine
or dual engines, depending on the options you
choose. The shift and throttle controls on your
boat will vary depending on the engines used.
The following control description is typical of most
outboard remote controls. Refer to the engine or
control manuals for specific information on the
controls installed on your boat.
Cable Engine Controls
The engine throttle and shift control systems
consist of three major components: the control
handles, the throttle cable and the shift cable. The
cables are all the push-pull type. Two cables are
required for each engine. One cable connects the
remote throttle control to the carburetor or fuel
injectors and the other connects the remote shift
control to the engine shift rod linkage.
The helm on your Scout is designed for a binnacle
style control with a single lever for each engine
that operates as a gear shift and a throttle. Gen-
eral operation will include a position for neutral
(straight up and down), a forward position (the
1st detent forward of neutral), and a reverse po-
sition (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.

Yamaha Single Engine Cable Control
The handles of dual lever controls may not always
align with each other at all RPM settings due to
variations in control cable routing, cable length
and adjustments at the engine. Usually the align-
ment of the handles can be optimized at a chosen
RPM, but may vary at other settings.
Electronic Engine Controls
Electronic engine controls are optional on some
Yamaha engines. The following control description
is typical of most electronic control installations.
