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. (See page 4-22
for adjustment procedures.)
Up position A:
There will be less water resistance in this
position, so straight-ahead acceleration
when on plane and top speed will be
enhanced.
Down position B:
This position will give the watercraft more
“hook” which will enhance turning perfor-
mance.

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. If tem-
porarily leaving the watercraft with a
full fuel tank, do not leave it in direct
sunlight. Leave it in a well-ventilated
area with the watercraft in a horizontal
position.

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.
@
CAUTION:@
Do not use leaded gasoline. Leaded
gasoline can seriously damage the
catalytic converter.

Use only fresh gasoline that has been
stored in clean containers.
@
Recommended gasoline:
Regular unleaded gasoline with
a minimum octane rating of
86 (Pump octane number) = (R+M)/2
90 (Research octane number)
