GENERAL
The O.T.A.S. (Off-Throttle Assisted Steering)
system provides additional maneuverability in
off-throttle situations.
The O.T.A.S. system is
electronically activated and slightly increases en-
gine speed under a pre-programmed RPM when
the driver initiates a full turn. When handlebar is
brought back to its center position, the throttle
reverts to idle.
Required Conditions to Activate
the System
• The engine speed must be above 4000 RPM.
• The throttle lever must be released quickly and
completely.
• The handlebar must be fully turned immediately
after throttle release.
TESTING PROCEDURES
Dynamic Test
This test is to be performed with the watercraft
in the water (regular riding or jet pump in water
with watercraft attached on a trailer and using the
digital tachometer (P/N 529 014 500)).
– Make sure the path ahead is clear.
– Raise engine RPM higher than 4000 RPM for
more than 1 second.
– Release throttle while steering is in the straight
ahead position.
– Within 1 to 3 seconds, turn handlebar all the
way to one side.
– The O.T.A.S. should come on for 1/2 second and
increase engine RPM within 2900 to 3900.
– If steering is kept in this position, the O.T.A.S.
will come on again every 2 seconds.
– Turn handlebar to other side quickly (within 1/2
second).
– The O.T.A.S. should still be active and come on
every 2 seconds.
If the RPM is not within the specified range, per-
form the O.T.A.S. CABLE ADJUSTMENT as de-
scribed further in this section.
If the RPM does not change, perform the STEER-
ING POSITION SWITCH tests. See below.
