DEFINITIONS
Conventional
Steering Control
This is the standard type of steering that has
been used on boats for many years. The steering
wheel is the only means of control.
Conventional Shift
and Throttle
The type of shift and throttle control where
standard control head levers allows the
engine gear selection and throttle control.
Electronic Shift
and Throttle
There are two types of electronic shift and
throttle (EST) system:
1) On engines that use mechanical levers to
control shift and throttle, instructions from
an electronic control head are transmitted
to electric actuators, which move mechanical
control cables accordingly.
This type of EST system may also be called an
MST or remote EST system to differentiate it.
2) Many modern engines have built-in actuators
to control shift and throttle. Instructions from
an electronic control head are transmitted
directly to the engine control computer.
This type of EST system may sometimes be
called an OEM EST or integrated EST system
to differentiate it.
This manual describes the operation of the
first type of EST system. When calling for
technical support, please make it clear which
type of system you are using.
Joystick Control A single handle joystick control device that
integrates the steering, the gear shift, and the
throttle control for multiple engines into one
easy-to-use device to provide docking control
of the vessel.
