Safety information
12
Avoid being hit by another boat. You
should always take the responsibility to
watch for traffic; other boaters may not be
watching for you. If they do not see you, or
if you maneuver more quickly than other
boaters expect, you risk a collision.
Maintain a safe distance from other boats
and watercraft, and also watch for ski
ropes or fishing lines. Obey the “Safe boat-
ing rules” and be sure to check behind you
before making a turn. (See “Safe boating
rules” on page 14.)
EJU30841
Recommended equipment
The following items should be carried on
board your watercraft:
Sound-signaling device
You should carry a whistle or other sound-
signaling device that can be used to signal
other boats.
Visual distress signals
It is recommended that a pyrotechnic de-
vice, which is approved by the appropriate
authorities, be stored in a waterproof con-
tainer on your watercraft. A mirror can also
be used as an emergency signal. Contact a
Yamaha dealer for more information.
Watch
A watch is helpful so you will know how
long you have been operating the water-
craft.
Towline
A towline can be used to tow a disabled
watercraft in an emergency.

EJU46520Reboarding holder
The reboarding holder is used when boarding
the watercraft from the water.
EJU34874Bow eye
The bow eye is used to attach a rope to the
watercraft when transporting, mooring, or
towing it in an emergency. (See page 73 for
information on towing the watercraft.)
EJU34883Stern eyes
The stern eyes are used to attach a rope to
the watercraft when transporting or mooring
it.
EJU31677Storage pouch
The storage pouch is located on the bottom
of the hood.
Use the storage pouch to store the own-
er’s/operator’s manual and other small items.
The storage pouch is not designed to be wa-
terproof. If you carry objects that must be
kept dry, put them in a waterproof bag.
To remove the storage pouch:
(1) Remove the hood. (See page 26 for hood removal and installation procedures.)
(2) Unfasten the bands, and then remove the storage pouch.

water flows out continually from the
cooling water pilot outlet.
(7) Run the engine at idling speed for about 3 minutes watching the engine condition.
If the engine stops while flushing, turn
the water supply off immediately and
perform the procedure again from step 6.
NOTICE: Do not supply water to the
cooling water passages when the en-
gine is not running. The water could
flow back through the muffler into the
engine, causing severe engine dam-
age.
[ECJ00123]
(8) Turn the water supply off.
(9) Discharge the remaining water out of the cooling water passages by alternately
squeezing and releasing the throttle lever
quickly for 10 to 15 seconds.
(10) Stop the engine.
(11) Remove the garden hose adapter, and then securely install the flushing hose
connector cap by tightening it until it
stops.
(12) Securely install the hood in its original position.
EJU40746Cleaning the watercraft
(1) Remove the hood. (See page 26 for hoodremoval and installation procedures.)
(2) If the watercraft will be stored for a week or more, rustproof the internal engine
components to help prevent corrosion. (See page 61 for information on rust-
proofing the internal engine compo-
nents.)
(3) Rinse the engine and engine compart- ment with a small amount of water.
NOTICE: Do not use high-pressure
water when rinsing the engine or en-
gine compartment as severe engine
damage could result.
[ECJ00572]
(4) Drain the water from the engine com- partment. (See page 35 for information
on draining the bilge water.)
(5) Wipe the engine and engine compart- ment with a dry cloth.
(6) Wash down the hull, deck, and jet pump with fresh water.
(7) Wipe the hull, deck, and jet pump with a dry cloth.
(8) Wipe all vinyl and rubber components, such as the engine compartment seals,
with a vinyl protectant.
(9) To minimize corrosion, spray metallic parts of the hull, deck, and engine with a
rust inhibitor.
(10) Allow the engine compartment to air dry completely before installing the hood.
(11) Securely install the hood in its original position.
EJU3368CBattery care
If the watercraft will not be used for more than
a month, remove the battery from the water-
craft, check it, and then store it in a cool, dry
place.
EWJ00793
Battery electrolyte is poisonous and dan-
gerous, causing severe burns, etc. Elec-
trolyte contains sulfuric acid. Avoid
contact with skin, eyes, or clothing.
Antidotes
External: Flush with water.

Throttle cable
Steering cable ball joint (handlebar end)
and steering cable inner wire (handlebar
end)
TIP:
Disconnect the steering cable (handlebar
end) from the ball joint before lubricating.
Steering cable (jet thrust nozzle end) and
ball joint
TIP:
Disconnect the steering cable from the ball
joint before lubricating.
EJU45861RustproofingECJ01361
Do not run the engine for more than 15
seconds on land without supplying water,
otherwise the engine could overheat.
Spray metallic parts of the hull and engine
with a rust inhibitor.
To rustproof the internal engine components:
(1) Remove the hood. (See page 26 for hoodremoval and installation procedures.)
(2) While loosening the clamp, remove the breather hose.
(3) Make sure that the area around the wa- tercraft is clear, and then start the engine
in a well-ventilated area.
(4) Run the engine at a fast idle.
(5) Quickly spray as much rust inhibitor as possible into the air intake duct through
the breather hose joint. Keep spraying
until the engine stalls (or a maximum of
15 seconds). WARNING! Do not pour or
spray gasoline, or any substance oth-
er than a rust inhibitor, into the air in-
take duct. Do not spray flammable
Recommended water-resistant grease:
