Ring Free Fuel Additive
Gasoline is a precise blend of many dif-
ferent substances, each chosen to give
certain characteristics. Gasoline blends
have been changing in recent years in
response to concerns about pollution
and resulting emissions regulations.
One of the most obvious changes has
been the elimination of lead from fuels.
As gasoline has changed, the amount
of additives such as aromatics and
oxygenates has increased. These ad-
ditives are important for the engines in
passenger cars, but they can have det-
rimental effects in marine engines.
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 LEVEL

Check the engine oil level before each
use.
WARNING
Engine oil is extremely hot immedi-
ately after the engine is turned off.
Coming in contact with or getting
any engine oil on your clothes could
result in burns.
NOTICE:
Make sure debris and water do not
enter the oil filler hole. Debris and
water in the engine oil can cause
serious engine damage.
To Check the Engine Oil Level:
1) Place the watercraft in a precisely
level position on land with the
engine stopped.
TIP:
If the engine was running, allow the
engine oil to settle by waiting 5 minutes
or more before checking the oil level.
2) Remove the dipstick, wipe it clean,
and then insert it back into the dip-
stick tube completely. Remove the
dipstick again and check that the
engine oil level is between the 
minimum and  maximum level
marks.
