Owner`s manual

While many additives available may
reduce deposits, Yamaha recommends
the use of Ring Free Fuel Additive,
available from your Yamaha dealer.
Ring Free has repeatedly proven its
ability to clean combustion deposits
from inside the engine, notably in the
critical piston-ring-land area, and fuel
system components. Follow product
labeling for use instructions.
ENGINE OIL
Recommended oil: YAMALUBE 4-M
FC-W
®
. If YAMALUBE 4-M FC-W
®
is
not available, another 10W-30, 4-cycle
engine oil with an API rating of SE, SF,
SG, SH, or SJ.
GASOLINE
AND ENGINE OIL
FILLING
FILLING THE GASOLINE TANK
Open the fuel tank filler cap, and slow-
ly add fuel to the fuel tank. Be careful
not to spill fuel or overfill the tank.
Stop filling when the fuel just becomes
visible in the bottom of the filler tube.
Do not “top off” the tank, because
gasoline could spill out. Be sure to
tighten the cap securely.
Be careful when refueling. Avoid
getting water or other contaminants
in the fuel tank. Contaminated fuel
can cause poor running or engine
damage.
Fuel tank capacity: 50 US gal. (189 lit)
ENGINE OIL LEVEL
Check the oil level in both engines
before each use. Check the oil on each
engine when cold to be sure there is
enough oil to run the engine.
Be sure the engine has enough oil
but do not overfill. If there is too lit-
tle oil, the engine can be damaged. If
there is too much oil, the air filter
can become saturated with oil, per-
manently damaging the filter and
reducing engine performance.
Follow the checking procedure care-
fully.
NOTE:
• Each engine has an oil-tank system.
It is normal for the oil level to vary
depending upon whether the engine
is cold or at operating temperature.
• Adding 1 US qt. (0.95 l) of oil will
raise the oil level on the dipstick by
approximately 2.2 in. (56 mm).
