Gasoline
Use a good quality gasoline that meets the
minimum octane requirement. If knocking or
pinging occurs, use a different brand of gas-
oline or premium unleaded fuel. Yamaha rec-
ommends that you use alcohol-free gasoline
(see Gasoline with Ethanol) whenever possi-
ble.
The use of a poor quality gasoline may result
in starting and running problems. If you en-
counter drivability problems, which you sus-
pect could be related to the fuel you are
using, Yamaha recommends that you switch
to a recognized high quality brand of gaso-
line, such as a gasoline that is advertised as
Top Tier Detergent Gasoline. (North America
only)
NOTICE:
Failure to comply with these
recommendations may also result in un-
scheduled maintenance, fuel system dam-
age, and internal engine damage.

NOTICE
ECM01982
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 or engine dam-
age. Use only fresh gasoline that has
been stored in clean containers.
Gasoline with Ethanol
Two types of gasoline are commonly avail-
able in the U.S.A., Canada, Australia and
New Zealand for use in automobiles and
boats: conventional gasoline without Ethanol
and gasoline with Ethanol, which is typically
referred to as E10 gasoline. According to fed-
eral regulations, E10 gasoline may contain up
to 10% Ethanol.
A high quality gasoline without Ethanol is the
preferred fuel for your Yamaha outboard mo-
tor. However, if gasoline with Ethanol is the
only fuel available in your area, your Yamaha
outboard motor is calibrated to run properly
on fresh E10 gasoline that meets the mini-
mum octane requirement specified for this
model.
NOTICE
ECM02402
Never use a gasoline for your outboard
motor that contains more than 10% Etha-
nol, such as E15 which contains 15% Eth-
anol or E85 which contains 85% Ethanol,
or gasoline containing any amount of
