Cruising limitations
Scan constantly for people, objects, and
other watercraft. Be alert for conditions
that limit your visibility or block your vision
of others.
Operate defensively at safe speeds and
keep a safe distance away from people,
objects, and other watercraft.
Do not follow directly behind watercraft or
other boats.
Do not go near others to spray or splash
them with water, go too close to other
boats, or go too fast for the traffic condi-
tions.
Take early action to avoid collisions. Re-
member, watercraft and other boats do not
have brakes. In addition, the Reverse with
Intuitive Deceleration Electronics (RiDE)
system is not a braking device for avoiding
dangerous situations. The RiDE system is
an electronic system for controlling the en-
gine speed and reverse gate, which is lo-
cated near the jet thrust nozzle. The RiDE
lever located at the left handlebar grip can
be used to change the direction of the jet
thrust so that the watercraft moves in re-
verse or is in neutral. The RiDE system as-
sists the operator when slowing down and
during slow-speed maneuvering, such as
launching, beaching, and docking.
Avoid sharp turns, slowing down rapidly by
squeezing the RiDE lever forcefully, and
other maneuvers that make it hard for oth-
ers to avoid you or understand where you
are going.
Avoid areas with submerged objects or
shallow water.
Do not release the throttle lever when trying
to steer away from objects—as with other
powerboats, you need throttle to steer. Al-
ways check throttle and steering controls
before starting the watercraft.
Ride within your limits and avoid aggres-
sive maneuvers to reduce the risk of loss of
control, ejection, and collision.
This is a high performance boat—not a toy.
Avoid aggressive operation, sharp turns,
and unexpected acceleration that can
cause you to be thrown off. Do not jump
waves or wakes—jumping can cause inju-
ries such as back or spinal injuries (paraly-
sis), facial injuries, and broken legs, ankles,
and other bones. Improper operation can
result in severe injury or death.
Do not operate the watercraft in rough wa-
ter, bad weather, or when visibility is poor;
this may lead to an accident causing injury
or death. Be alert to the possibility of ad-
verse weather. Take note of weather fore-
casts and the prevailing weather
conditions before setting out on your wa-
tercraft.
As with any water sport, you should not op-
erate your watercraft without someone else
nearby. If you operate further than swim-
ming distance from shore, you should be
accompanied by another boat or water-
craft, but make sure you stay a safe dis-
tance away. It’s good, common sense.
Never operate in water that is less than 60
cm (2 ft) deep from the bottom of the wa-

Hazard information
Never start the engine or let it run for any
length of time in an enclosed area. Exhaust
fumes contain carbon monoxide, a color-
less, odorless gas that may cause loss of
consciousness and death within a short
time. Always operate the watercraft in an
open area.
Do not touch the hot oil tank, muffler, or en-
gine during or immediately after engine op-
eration; they can cause serious burns.
Do not place magnets or objects with a
strong magnetic force near the throttle le-
ver or RiDE lever. The electronic throttle
mechanism of the levers can be adversely
affected, which could cause loss of control.
In addition, do not place objects suscepti-
ble to magnetic forces (i.e., credit cards,
watches, etc.) close to the throttle lever or
RiDE lever.
EJU42415
Watercraft characteristics
Jet thrust turns the watercraft. 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.
This model is equipped with the Yamaha
Engine Management System (YEMS) that
includes an off-throttle steering (OTS) sys-
tem. It will activate at planing speeds
should you attempt to steer the watercraft
after releasing the throttle lever. The OTS
system assists in turning by continuing to
supply some thrust while the watercraft is
decelerating, but you can turn more sharp-
ly if you apply throttle while turning the han-
dlebars.
The OTS system does not function below
planing speeds or when the engine is off.
Once the engine slows down, the water-
craft will no longer turn in response to han-
dlebar input until you apply throttle again or
you reach trolling speed.
Practice turning in an open area without
obstacles until you have a good feel for this
maneuver.
This watercraft is water-jet propelled. The
jet pump is directly connected to the en-
gine. This means that jet thrust will produce
some movement whenever the engine is
running and the “F” (forward) or “R” (re-
verse) shift indicator is displayed. When the
“N” (neutral) shift indicator is displayed, the
forward and reverse thrust are balanced to
help keep the watercraft from moving in ei-

er’s or water-skier’s ability, as well as water
and weather conditions.
When preparing to pull a wakeboarder or
water-skier, operate the watercraft at the
slowest possible speed until the watercraft
is well away from the person being pulled
and slack in the ski rope is taken up. Make
sure that the rope is not looped around
anything.
After checking that the wakeboarder or wa-
ter-skier is ready and that there is no traffic
or other obstacles, apply enough throttle to
raise the person.
Make smooth, wide turns. The watercraft is
capable of very sharp turns, which could
exceed the abilities of the wakeboarder or
water-skier. Keep the person being towed
at least 50 m (164 ft), about twice the dis-
tance of a standard ski rope, away from
any potential hazard.
The operators of boats and other water-
craft may not be aware that you are pulling
a wakeboarder or water-skier. Together
with the spotter, pay attention to others
around you and cruise at safe speeds.
Be alert to the hazard of the ski rope handle
snapping back at the watercraft when the
wakeboarder or water-skier falls or is un-
able to get up.
Towing heavy or bulky objects other than
wakeboarders or water-skiers, such as an-
other boat or watercraft, can cause loss of
steering control and create a hazardous
condition. If you must tow another boat in
an emergency situation, operate slowly
and cautiously.

Watercraft glossary
Trolling speed
“Trolling” is the lowest maneuvering speed. You are applying little or no throttle. The water-
craft is down in the water, and there is no wake.
Sub-planing speed
“Sub-planing” is a medium speed. The bow of the watercraft is slightly up from the water sur-
face, but you are still traveling through the water. There is a wake.
Planing speed
“Planing” is a faster speed. The watercraft is more level and is skimming on top of the water.
There is a wake.
Bow
The front end of the watercraft.
Stern
The rear end of the watercraft.
Starboard
The right side of the watercraft when facing forward.
Port
The left side of the watercraft when facing forward.
Bilge water
Water that has collected in the engine compartment.
Yamaha Engine Management System (YEMS) YEMS is an integrated, computerized management system that controls and adjusts ignition
timing, fuel injection, engine diagnostics, and the off-throttle steering (OTS) system.
Reverse with Intuitive Deceleration Electronics (RiDE)
RiDE is an electronic system that controls the reverse, neutral, and deceleration operations of
the watercraft.

will not start. Also, the starter motor could
be damaged.
[ECJ01041]
The engine will not start under any of the fol-
lowing conditions:
Clip is removed from the engine shut-off
switch.
Throttle lever is squeezed.
Throttle lever is malfunctioning.
RiDE lever is squeezed.
RiDE lever is malfunctioning.EJU31212Throttle lever
The throttle lever increases the engine speed
when the lever is squeezed.
The throttle lever returns automatically to its
fully closed (idle) position when released.
EJU43342RiDE lever
When the RiDE lever is squeezed, the reverse
gate lowers and the watercraft starts movingin reverse. If the watercraft is moving forward,
the watercraft gradually slows down until it
stops, and then the watercraft starts moving
in reverse.
When the RiDE lever is released, it automati-
cally returns to its fully closed (idle) position
and the reverse gate moves to the neutral po-
sition.

zle is changed, and the direction of the water-
craft is changed accordingly.
Since the strength of the jet thrust determines
the speed and degree of a turn, throttle must
always be applied when attempting a turn,
except at trolling speed.
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. The OTS system assists in
turning by continuing to supply some thrust
while the watercraft is decelerating, but you
can turn more sharply if you apply throttle
while turning the handlebars. The OTS sys-
tem does not function below planing speeds
or when the engine is off. Once the engine
slows down, the watercraft will no longer turn
in response to handlebar input until you apply
throttle again or you reach trolling speed.EJU35975Cooling water pilot outlet
When the engine is running, some of the
cooling water that is circulated in the engine
is discharged from the cooling water pilot
outlet.
There is a cooling water pilot outlet on the
port (left) side of the watercraft. To check for
proper operation of the cooling system, make
sure that water is being discharged from the
cooling water pilot outlet. If water is not being
discharged from the outlet, stop the engine
and check the jet intake for clogging. (See
page 85 for information on the jet intake.)
TIP:
It will take about 60 seconds for the water
to reach the outlet after the engine is start-
ed.
Water discharge may not be constant
when the engine is running at idling speed.
If this occurs, apply a little throttle to make
sure that water discharges properly.
EJU40323Water separator
The water separator prevents water from en-
tering the fuel tank by collecting any water
that has entered the fuel tank breather hose if
the watercraft was capsized.
