Helm Control Systems
4.7 Joystick Controls
A joystick control system is an option on some engine
installations with electronic steering. The joystick
can only be used at slow speeds. It is engaged by
moving the shift and throttle controls to the neutral
position and pressing the JOYSTICK button on the
base of the joystick control or the keypad on the main
engine controls. Once activated, the boat moves in
the direction the joystick is pushed with the engine
speed increasing the further the stick is pushed, up
to preset limits. Turning the knob on the top of the
joystick rotates the boat in the direction the knob
is turned. Another button on the joystick or engine
control key pad raises the preset engine speed for
maneuvering in high winds and/or strong tides.
When the joystick is released, it automatically re-
turns to center, the engines shift to neutral, rotate
to the straight ahead position, and the engine speed
is reduced to idle. It is deactivated by pressing the
JOYSTICK button at the base of the joystick or control
keypad or by moving the shift and throttle control
levers.
Both engines must be running for the joystick control
to maneuver boat properly.
Always refer to the engine manufacturer owner’s
manuals for specic information on the operation
and maintenance for the joystick and steering control
systems on your boat.
SOME JOYSTICKS AND ELECTRONIC CONTROL SYSTEMS
ARE EQUIPPED WITH A FEATURE WHICH USES THE ENGINES
TO AUTOMATICALLY HOLD THE BOAT IN POSITION. THIS
FEATURE CAN CAUSE SERIOUS INJURY OR DEATH TO
PERSONS SWIMMING NEAR THE BOAT OR ATTEMPTING
TO BOARD WHEN IT IS ACTIVATED.
WHEN THE POSITION HOLDING FEATURE IS ACTIVATED:
THE PROPELLERS ROTATE AUTOMATICALLY;
PROPELLER ROTATION MAY NOT BE OBVIOUS;
THE BOAT MAY SUDDENLY MOVE IN ANY DIRECTION;
THE PROPELLERS CAN INJURE PEOPLE IN THE WATER
ANYWHERE AROUND THE BOAT.
IF YOUR BOAT IS EQUIPPED WITH A POSITION HOLDING
FEATURE, THE FOLLOWING PRECAUTIONS APPLY:
ALWAYS ASK THE CAPTAIN BEFORE ENTERING THE WATER.
UNLESS THE CAPTAIN GIVES YOU PERMISSION:
DO NOT GO IN THE WATER; WIND OR WATER CURRENT CAN
MOVE SWIMMERS INTO THE PROPELLERS.
DO NOT SIT OR STAND WHERE YOU COULD FALL
OVERBOARD; YOU MAY LOSE YOUR BALANCE IF THE BOAT
MOVES SUDDENLY.
