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
The shift and throttle controls on your boat may
vary depending on the engines used. The following
description is typical of most cable and electronic
inboard/outboard remote controls. Refer to the
engine or control manual for specific information
on the controls installed on your Boat.
Cable Engine Controls
The cable engine throttle and shift control system
consists 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 con-
nects the remote throttle control to the engine
and the other connects the remote shift control
to the outdrive shift linkage.
The helm on your Monterey is designed for a bin-
nacle style 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 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.
Electronic Engine Controls
Electronic engine controls are standard on diesel
powered boats and optional with gasoline engines.
Volvo Engine Controls and Control Head
The shift and throttle control features may vary
depending on the engines used. The following
control description is typical of most electronic
control installations.
The helm is designed for a binnacle style control
with a single lever for each engine. The electronic
control system consists of three major compo -
nents: the electronic control head with integrated
or separate keypad, the control processors and ap-
plicable harnesses. Some controls are completely
electronic and there are no cables. Some control
processors have electronically controlled servos
that are connected to the engine and transmission
control levers by cables.
Movement of the helm control arm sends a signal
to the control processor, located in the engine
