Chapter 5: Instrumentation
Digital Electric Steering (DES)
The DES package uses an electric actuator to steer each engine. The Digital Steering
Helm and Digital Electric Control send signals to the engine and Steering Control Unit
(SCU), which control the operation of the electric steering actuator(s) on the engine(s). The SCU
receives signals from the steering actuator position sensors and the Boat Control Units (BCUs) to
carry out steering and joystick (if equipped) operation.
Autopilot
The Autopilot system is an automatic piloting function that assists with steering and
throttle operations to keep the boat moving to a desired point or heading. Adjustments to
a heading or course are done through the use of the Autopilot panel or through an aftermarket
Multi-Function Display (MFD).
a. Heading Hold: This allows the boat to continue moving in the same direction as when the
mode was set.
b. Course Hold: This allows the boat to keep a course to a specific waypoint, compensating
for wind and current.
c. Pattern Steer: This allows the boat to steer along a pattern pre-set on the MFD by the
user.
d. Track Point: This allows the boat to move along a series of waypoints inputted by the user
set of the MFD. Depending on settings, it can slow or stop the boat when it reaches its
final destination.
Full Maneuverability
Helm Master EX™ Full Maneuverability Package is a fully integrated boat control system
for Yamaha outboard-powered boats, in twin, triple, or quad engine configurations,
which includes digital electronic steering, digital electronic throttle and shift, and a joystick control
to facilitate docking. It also includes a virtual anchoring system, called “Set Point.”
The Helm Master EX™ Set Point has four primary modes: Stay Point™, Fish Point™, Drift
Point™ and Drift Point Track™. Each Set Point mode provides a solution to maneuvering challenges
boaters may encounter.
a. Stay Point: Stay Point keeps the boat positioned near a particular spot; it maintains a
selected position and heading.
b. Fish Point: Fish Point enhances fishing options; it maintains a selected position, but not a
heading, and primarily uses only idle RPM to do so.
c. Drift Point: Drift Point allows the boater to drift the boat with the wind or the current; it
maintains a selected heading, but not a position.
d. Drift Point Track: This allows the boat to drift along a route set by the user.
