Helm Master™ is an optional fully integrated boat control system for Yamaha outboard-
powered boats, in twin or triple engine configurations, which includes digital electronic steering,
digital electronic throttle and shift, and a joystick control to facilitate docking.
On the joystick are two control selector buttons. The Joystick selector activates the joystick.
The remote control must be in the neutral (center) position for this selector to be activated. The
High Mode selector allows for increased engine RPM. The joystick controls the side to side and
rotational movement of the vessel. The operator is the central pivot point around which the boat
moves and the further one moves the joystick, the greater the thrust and speed in that direction.
Return the joystick to the neutral position when finished maneuvering. Operating the throttle
disengages the joystick and returns operation to the remote control box and steering wheel.
The Digital Steering Helm sends signals to the Powertrain Control Units (PCU), which
control the operation of the electric pumps that pump hydraulic fluid to the steering cylinders on
the engines. The Steering Control Unit (SCU) receives signals from the steering cylinder position
sensors and the PCU's to carry out joystick and steering operation. One by-pass valve assembly
per engine is required, and allows the hydraulic pump system to be by-passed in an emergency or
for maintenance.
The Digital Remote Control has 6 control selector buttons whose activation is indicated by a
green LED. The Speed Control selector is used to set the RPM's throughout the range of the
engine. The Single Lever selector allows the port lever to control the shifting and speed of all
engines. The Station Selector is used to select the active station on boats with two stations. The
Center Engine selector allows the port lever to control the center engine only. The Trim Assist
selector allows the operator to synchronize the trim angle to a given RPM so that the engine will
trim to the desired angle. The Free Throttle selector allows the selected engine to be throttled up
with the shift function disengaged.
The Electronic Key Switch uses a radio frequency key to power the main switch panel. Touch
the key to the panel and two audible beeps indicate the system is unlocked. Press the Ignition
button, then the Start/Stop button to start the engines. To engage the Y-COP security system touch
the key to the panel after the engines are turned off. A single audible beep indicates the system is
immobilized.
The Command Link Plus® display allows the operator to adjust and customize settings,
though some settings must be adjusted by an authorized technician. The information provided
here is only intended to be an overview of the system. For complete details on the operation and
set-up of the Helm Master system please refer to the Yamaha owner's manual or consult your
dealer.
