STEERING CONTROL SYSTEM
STEERING SYSTEM
The 36z has an integrated, electronically controlled power steering system, which through electric
motors rotate the two sterndrive units mounted on the transom. When running, the 36z is steered
as with outboards. Thrust of the propellers is directed more immediately and precisely from side
to side through a 26° arc to steer the boat.... rather than bouncing the prop wash pf a
conventional straight shaft propulsion unit off a rudder.
When the throttle/shift levers are put in (N) neutral and the left-hand button pushed to activate the
joystick: Control of the pod drives is transferred from the throttle/shift levers to the joystick that
controls the steering computer. When the joystick is activated, the steering wheel is inoperative.
Emergency Alignment If a fault occurs which prevents one or both of the sterndrives from
being operated with the steering wheel, it is possible to align the faulty propulsion unit(s) so that
its aimed straight ahead (and won’t act like a rudder), so as not to impair operation of either the
remaining propulsion unit or the steering of the boat with the two engines. See the Yanmar Owner’s
Operating Manual.
Emergency Steering These controls are attached to the engine with cables, so if the electronic
steering ever failed on both propulsion units, a steering method using the two engines can be
employed.
Emergency Shifting In an emergency, you should be able to shift the drives manually. There
is a shift actuator that normally shifts the mechanical drive, if that is not functioning, you may
be able to remove the cable from the shift actuator and manual push/pull the cable to shift into
gear.
JOYSTICK DOCKING CONTROL
This control is used only for docking and maneuvering
at slow speed. Learn to handle the joystick in a safe
and correct manner before you start using the function
in tight quarters.
When the joystick is active, the
normal engine controls are Neutral and inactive. A
computer operates the drives and shifting. Rotation of
the wheel is frozen and it should not be turned, as
damage may occur.
To Activate: Both engines must be running and the
engine control handles must be IN NEUTRAL. Press
the “Take Command” button. A beep confirms it is active
and the light above will go on.
To DeActivate: Press the ”Take Command” button on
the engine controls.
Boost Function In windy weather or current when you
need more oomph, push the BOOST button. A beep will
confirm it’s engaged.
Maneuvering with Joystick Lean the joystick post in the direction you’d like to go. Release and
the thrust stops. The boat may keep moving, so you may have to tap it in the opposite direction to
stop it. The top of the joystick is rotated (twisted) to orient the bow and stern, or to spin the boat
completely around on its own axis. Pretty simple Takes some practice until it becomes completely
intuitive.
