Safety information

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 muffler or engine dur-
ing or immediately after engine operation;
they can cause serious burns.
●Do not place magnets or objects with a
strong magnetic force near the throttle le-
ver. The electronic throttle mechanism can
be adversely affected, which could cause
loss of control. In addition, do not place ob-
jects susceptible to magnetic forces (i.e.,
credit cards, watches, etc.) close to the
throttle lever.
EJU42411
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 re-
leasing the throttle lever. The OTS system
assists in turning by continuing to supply
some thrust while the watercraft is deceler-
ating, but you can turn more sharply if you
apply throttle while turning the handlebars.
The OTS system 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.
Practice turning in an open area without ob-
stacles until you have a good feel for this
maneuver.
●This watercraft is water-jet propelled. The
jet pump is directly connected to the engine.
This means that jet thrust will produce some
movement whenever the engine is running
and the shift lever is in the forward or re-
verse position. The neutral position balanc-
es forward and reverse thrust to help keep
the watercraft from moving in either direc-
tion, although some movement may occur.
●Do not use the reverse function to slow
down or stop the watercraft as it could
cause you to lose control, be ejected, or im-
pact the handlebars.
This could increase the risk of back/spinal
injury (paralysis), facial injuries, and broken

cap. (See page 100 for information on the
fuse puller.)
(5) Securely install the fuse cover, and then
fit the bilge pump fuse holder into the rub-
ber cover.
(6) Secure the bilge pump fuse leads and
corrugated tube with the plastic ties.
(7) Securely install the seats in their original
positions.If the fuse immediately blows again, the elec-
trical system may be defective. If this occurs,
have a Yamaha dealer service the watercraft.
EJU34715Towing the watercraft
WARNING
EWJ00811
●The operator of the towing boat must
keep speed to a minimum and avoid traf-
fic or obstacles which could be a hazard
to the operator on the watercraft.
●The towline should be long enough so
that the watercraft will not collide with
the towing boat when slowing down.
If the watercraft becomes inoperative in the
water, it can be towed to shore.
To tow the watercraft:
Use a towline that is three times the combined
length of the towing boat and the watercraft.
(1) Securely attach the towline to the bow
eye of the watercraft being towed.
(2) Sit astride the seat and hold on to the
handlebars in order to balance the water-
craft. NOTICE: The bow must be kept
up out of the water during towing, oth-
erwise water could flood the engine
compartment or water could flow back
into the engine, causing severe en-
gine damage.
