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 gas-
oline can seriously damage the engine.
●
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.
●
AR195/SX195: Use only gasoline with a
minimum pump octane number of 91 or
a minimum research octane number of
95. Low-octane gasoline can seriously
damage the engine.
AR190/SX190
AR195/SX195
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. If
knocking (or pinging) occurs, use a gasoline
of a different brand.
Gasohol
There are two types of gasohol: gasohol con-
taining ethanol and that containing methanol.
Gasohol containing ethanol can be used if
ethanol content does not exceed 10% and the
fuel meets minimum octane ratings. E-85 is a
fuel blend containing 85% ethanol and there-
fore must not be used in this boat. All ethanol
blends containing more than 10% ethanol can
cause fuel system damage or engine perfor-
mance problems.
Yamaha does not recommend gasohol con-
taining methanol because it can cause fuel
system damage and engine performance
problems.
To fill the fuel tank:
(1) Before refueling, turn off the engine. Nev-
er refuel while smoking, or while in the vi-
cinity of sparks, open flames, or other
sources of ignition.
(2) Refuel the boat in a well-ventilated area.
If the boat is in the water, be sure it is se-
curely moored to the fueling dock. All
passengers must be out of the boat dur-
ing refueling.
(3) Press the fuel tank filler cap button, and
then open the fuel tank filler cap.
Recommended fuel:
Regular unleaded gasoline with a
minimum octane rating of 86
(Pump octane number) = (R + M)/2
90 (Research octane number)
Recommended fuel:
Premium unleaded gasoline with a
minimum octane rating of 91
(Pump octane number) = (R + M)/2
95 (Research octane number)
