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.
The engine manufacturer supplies the control
systems for the Volvo IPS drives and provides
owner's manuals 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 slightly depending on the engines used. The
following description is typical of most electronic
IPS remote controls. Refer to the engine or control
manual for specific information on the controls
installed on your boat.
Electronic Engine Controls
Electronic engine controls are standard on the
Volvo IPS drives. The following control description
is typical of most electronic control installations.
Volvo Engine Controls and Control Head
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, an EVC (Elec-
tronic Vessel Control) keypad, the control proces-
sors and applicable harnesses. The controls are
completely electronic and there are no cables.
Movement of the helm control arm sends a signal
to the control processor, located in the engine
compartment that operates the engine throttle
and transmission control lever. 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 engine
Electronic Vessel Control (EVC)
to be operated at a higher than idle RPM while in
