Section 06 STEERING AND PROPULSION
Subsection 01 (STEERING AND O.T.A.S.)
GENERAL
During assembly/installation, use torque values
and service products as in the exploded view.
Clean threads before applying a threadlocker. Re-
fer to
SELF-LOCKING FASTENERS and LOCTITE
APPLICATION
at the beginning of this manual for
complete procedure.
WARNING
Torque wrench tightening specifications
must be strictly adhered to.
Locking devices (e.g.: locking tabs, elastic
stop nuts, self-locking fasteners, cotter pins,
etc.) must be replaced with new ones.
Hoses, cables or locking ties removed during a
procedure must be reinstalled as per factory stan-
dards.
SYSTEM DESCRIPTION (O.T.A.S.)
The O.T.A.S. (Off-Throttle Assisted Steering) pro-
vides additional maneuverability in off-throttle sit-
uations.
The system uses a pair of magnets mounts on the
steering column and a Hall effect switch mounts
underneath steering column support.
When activated by a magnet, the O.T.A.S. switch
sends a signal to the ECM.
The ECM activates a pre- programmed RPM set-
ting when the driver initiates a full turn after relea-
sing throttle lever. The engine RPM is controlled
by the intelligent Throttle Control (iTC).
The O.T.A.S. system is activated when the follow-
ing conditions are achieved:
– The engine speed must be above 4000 RPM for
at least 1.5 second (approximately).
– The throttle lever must be released completely.
– The steering must be fully turned within approx-
imately 4 seconds after throttle release.
The O.T.A.S. will stay activated for a random
period of time as long as the O.T.A.S. switch is
closed.
O.T.A.S. will be deactivated if:
– The throttle is reapplied, or
– The steering is turned sufficiently to open the
O.T.A.S. switch for more than one second.
ADJUSTMENT
STEERING ALIGNMENT
Raise the iBR gate by activating the iBR override
function. Refer to
IBR AND VTS

Install two bungee cords to maintain steering dur-
ing the procedure.
Position steering so that the edge of the steering
column cover and edge of the gauge support are
equal.

2. Gauge support edge
Check jet pump nozzle position by placing a
straight edge on nozzle outer end. Measure the
distance on each side of the straight edge. It
must be equalled.
