Fuel

WARNING
Gasoline and gasoline vapors are ex-

tremely flammable. To avoid fires and
explosions and to reduce the risk of in-
jury when refueling, follow these in-
structions.
Gasoline is poisonous and can cause in-

jury or death. Handle gasoline with care.
Never siphon gasoline by mouth. If you
should swallow some gasoline, inhale a
lot of gasoline vapor, or get some gaso-
line in your eyes, see your doctor imme-
diately. If gasoline spills on your skin,
wash with soap and water. If gasoline
spills on your clothing, change your
clothes.

NOTICE
Do not use leaded gasoline. Leaded

gasoline can seriously damage the en-
gine.
Avoid getting water and contaminants in

the fuel tank. Contaminated fuel can
cause poor performance and engine
damage. Use only fresh gasoline that
has been stored in clean containers.
Recommended fuel:
Regular unleaded gasoline with a
minimum octane rating of
86
(Pump octane number) = (R + M)/2
90 (Research octane number)
Gasohol
There are two types of gasohol: gasohol con-
taining ethanol and that containing methanol.

Operation and handling requirements

Gasohol containing ethanol can be used if
ethanol content does not exceed 10% and
the fuel meets the minimum octane ratings.
E-85 is a fuel blend containing 85% ethanol
and therefore must not be used in this water-
craft. All ethanol blends containing more than
10% ethanol can cause fuel system damage
or engine performance problems.
Yamaha does not recommend gasohol con-
taining methanol because it can cause fuel
system damage and engine performance
problems.

2-stroke engine oil

Recommended engine oil:
YAMALUBE 2-W or TC-W3 outboard
motor oil or equivalent
If YAMALUBE 2-W engine oil is not available,
another 2-stroke engine oil with an NMMA-
certified TC-W3 rating may be used.

Why Yamalube

YAMALUBE oil is a Genuine YAMAHA Part
born of the engineers' passion and belief that
engine oil is an important liquid engine com-
ponent. We form teams of specialists in the
fields of mechanical engineering, chemistry,
electronics and track testing, and have them
develop the engine together with the oil it will
use. Yamalube oils take full advantage of the
base oil's qualities and blend in the ideal bal-
ance of additives to make sure the final oil
clears our performance standards. Thus,
Yamalube mineral, semisynthetic and syn-
thetic oils have their own distinct characters
and value. Yamaha's experience gained over
many years of research and development
into oil since the 1960's helps make
