EJU33254Turning the watercraft
WARNING
EWJ00771

Do not release the throttle lever when
trying to steer away from objects—you
need throttle to steer. A collision could
result in severe injury or death.

When operating at higher speeds, make
gradual turns or slow down before turn-
ing. Sharp high-speed turns may cause
the watercraft to slide sideways or spin,
throwing the operator and passenger(s)
overboard, which could cause an injury.
Steering control depends on the combination
of handlebar position and the amount of throt-
tle.Water sucked in through the intake grate is
pressurized by the impeller in the jet pump. As
the pressurized water is expelled from the
pump through the jet thrust nozzle, it creates
thrust to move and steer the watercraft. The
higher the engine speed, the more thrust pro-
duced.
The amount of jet thrust, in addition to the po-
sition of the handlebars, determines how
sharply you turn.
A. More throttle produces higher thrust, so
the watercraft will turn more sharply.
B. Less throttle produces lower thrust, so
the watercraft will turn more gradually.
C. Releasing the throttle lever completely
produces only minimum thrust. If you are
traveling at speeds above trolling, you will
have rapidly decreasing ability to steer
without throttle. You may still have some
turning ability immediately after releasing
the throttle lever, but once the engine

slows down, the watercraft will no longer
respond to handlebar input until you ap-
ply throttle again or you reach trolling
speed.
At trolling speed, the watercraft can be
turned gradually by handlebar position
alone using just the amount of thrust
available at idle.
D. If the engine is stopped while riding, there
is no thrust. The watercraft will go straight
even though the handlebars are turned.
You need throttle to steer.
This model is equipped with the Yamaha En-
gine Management System (YEMS) that in-
cludes an off-throttle steering (OTS) system.
It will activate at planing speeds should you
attempt to steer the watercraft after releasing
the throttle lever (see condition C above).
The OTS system assists in turning by continu-
ing to supply some thrust while the watercraft
is decelerating, but you can turn more sharplyif you apply throttle while turning the handle-
bars. The OTS system does not function be-
low planing speeds or when the engine is off.
Once the engine slows down, the watercraft
will no longer turn in response to handlebar in-
put until you apply throttle again or you reach
trolling speed.
EJU37511Stopping the watercraft
The watercraft is not equipped with a sepa-
rate braking system. It is stopped by water re-
sistance when the throttle lever is released.
From full speed, the watercraft comes to a
complete stop in approximately 130 m (430 ft)
after the throttle lever is released or the en-
gine is stopped, although this distance will
vary depending on many factors, including
gross weight, water surface conditions, and
wind direction. The watercraft slows down as
soon as the throttle lever is released, but will
coast for a distance before fully stopping. If
you are not sure you can stop in time before
hitting an obstacle, apply throttle and turn in
another direction.
WARNING
EWJ00742

Allow adequate stopping distance.

Take early action to avoid collisions. Re-
member, watercraft and other boats do
not have brakes.

Operate defensively at safe speeds and
keep a safe distance away from people,

Care and storage

EJU33492
Long-term storage
WARNING
EWJ00330
Always place the watercraft upright in a
horizontal position when storing it, other-
wise fuel could leak out into the engine or
engine compartment, which could create a
fire hazard.
Storage for long periods of time, such as win-
ter storage, requires preventive maintenance
to ensure against deterioration. It is advisable
to have the watercraft serviced by a Yamaha
dealer prior to storage.
However, the following procedures can be
performed easily by the owner.
EJU40762Cleaning
(1) Flush the cooling water passages. (See
page 77 for information on flushing the
cooling water passages.)
TIP:
If you will be storing the watercraft for a pro-
longed period, such as winter storage, top off
the fuel tank with fresh gasoline and add fuel
stabilizer and conditioner to the fuel tank ac-
cording to the manufacturer’s instruction be-
fore starting the engine.
(2) Clean the watercraft. (See page 78 for in-
formation on cleaning the watercraft.)
Wax the hull with a non-abrasive wax.
EJU41260Lubrication
Use a suitable marine grease applicator to
pressure-lubricate the cables and purge out
any moisture between the inner and outer ca-
bles.
To keep moving parts sliding or rotating
smoothly, lubricate them with water-resistant
grease.

Spray metallic parts of the hull, deck, and en-
gine with a rust inhibitor.Recommended water-resistant grease:

Yamaha dealer perform the checks in the following chart. However, maintenance may need to
be performed more frequently depending on your operating conditions. If you have any ques-
tions, consult a Yamaha dealer.
