Yamaha Adjustable Sponson
(Y.A.S.)
The sponsons 1 have adjustable posi-
tioning to allow the operator to enhance
either straight-line performance or turning
performance according to the preference
and operating conditions.
Adjusting to upward A:
There will be less water resistance in this
position, so straight-ahead acceleration
when on plane and top speed will be
enhanced.
Adjusting to downward B:
This position will give the watercraft more
“hook” which will enhance turning perfor-
mance.

Fuel and oil
This engine uses Yamaha’s oil injection
system, which provides superior lubrication
by ensuring the proper oil ratio for all operat-
ing conditions. No fuel premixing is neces-
sary except during the engine break-in
period. Simply pour gasoline into the fuel
tank and oil into the oil tank.
EJU01042
Gasoline
WARNING@ GASOLINE AND ITS VAPORS ARE
HIGHLY FLAMMABLE AND EXPLOSIVE!

Do not smoke when refueling, and
keep away from sparks, flames, or
other sources of ignition.

Stop engine before refueling.

Refuel in a well-ventilated area. Do not
stand or sit on the watercraft while
refueling in case of fire.

Take care not to spill gasoline. If gaso-
line spills, wipe it up immediately with
dry rags. Always properly dispose of
gasoline-soaked rags.

Avoid overfilling the fuel tank. Stop fill-
ing when the fuel level just reaches the
bottom of the filler tube. Do not fill up
the filler tube because fuel expands as
it warms up and could overflow.

Tighten the filler cap securely after
refueling.

If you should swallow some gasoline,
inhale a lot of gasoline vapor, or get
gasoline in your eyes, get immediate
medical attention.

If any gasoline spills onto your skin,
immediately wash with soap and
water. Change clothing if gasoline
spills on it.

Water separator
Check the water separator 1 for water.
Normally the water separator is empty. The
water separator retains any water entering
through the fuel tank breather hose if the
watercraft is capsized.
If water remains in the water separator,
drain it by removing the drain screw 2.
Install the drain screw again after draining
the water separator.
EJU01053
Bilge
Check for moisture and fuel residue in the
bilge.
Excessive water in the bilge can splash
into the carburetor and engine which could
cause engine damage.
To remove water from the bilge:
1. Remove the stern drain plugs.
2. Raise the bow of the watercraft until the
water drains.
3. After the water has drained, wipe the
bilge with dry rags to make sure that the
bilge is thoroughly dry.
4. Install the drain plugs.
CAUTION:@
Make sure that the stern drain plugs
are tightened securely before launch-
ing the watercraft.

Clean any foreign materials, such as
dirt or sand, from the drain plug
threads before installing the drain
plugs.
