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.
ECJ01870
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.
Use only gasoline with a minimum pump
octane number of 91 or a minimum re-
search octane number of 95. Low-oc-
tane gasoline can seriously damage the
engine.
Your Yamaha engine has been designed to
use premium unleaded gasoline with a pump
octane number [(R+M)/2] of 91 or higher, or a
research octane number of 95 or higher. Ifknocking (or pinging) occurs, use a gasoline
of a different brand.
TIP
This mark identifies the recommended fuel
for this watercraft as specified by European
regulation (EN228).
Check that the gasoline nozzle has the
same identifier when fueling.
Gasohol
There are two types of gasohol: gasohol con-
taining ethanol and gasohol containing meth-
anol.
Gasohol containing ethanol can be used if
the ethanol content does not exceed 10%
and the fuel meets th
e minimum octane rat-
ings. E-85 is a fuel blend containing 85% eth-
anol and therefore must not be used in this
watercraft. All ethanol blends containing
more than 10% ethanol can cause fuel sys-
tem damage or engine performance prob-
lems.
Yamaha does not recommend gasohol con- taining methanol because it can cause fuel Recommended fuel:
Premium unleaded gasoline with a
minimum octane rating of 91
(Pump octane number) = (R + M)/2
95 (Research octane number)
