Specifications and requirements
16
proved remote control units are equipped
with start-in-gear protection device(s). This
feature permits the engine to be started only
when it is in neutral. Always select neutral
before starting the engine.
EMU25661
Engine oil requirements
Use Yamalube 2-M outboard oil. If Ya-
malube 2-M is not available, use only anoth-
er outboard motor manufacturer’s factory-
brand oil with TC-W3 rating.
NOTICE
ECM01290
Serious engine damage can result from
the use of lower quality oil, including
some commonly available oil brands with
“TC-W3” on their label. To avoid the risk,
use only Yamalube 2-M or, if necessary,
another outboard motor manufacturer’s
factory-brand TC-W3 oil.

Fuel requirements
EMU36781
Gasoline
Use a good quality gasoline that meets the
minimum octane rating. If knocking or ping-
ing occurs, use a different brand of gasoline
or premium unleaded fuel. Yamaha re-
comends that you use alcohol-free (see
Gasohol) gasoline whenever possible.
NOTICE
ECM01981
●
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
damage. Use only fresh gasoline that
has been stored in clean containers.
Gasohol
There are two types of gasohol: gasohol con-
taining ethanol (E10) and that containing
methanol. Ethanol can be used if the ethanol
content does not exceed 10% and the fuel
meets the minimum octane ratings. E85 is a
fuel containing 85% ethanol and must not be
used in your outboard motor. All ethanol
blends containing more than 10% ethanol
can cause fuel system damage or cause en-
gine starting and running problems. Yamaha
does not recommend gasohol containing
methanol because it can cause fuel system
damage or engine performance problems.
It is recommended that you install a water-
separating marine fuel filter assembly (10
micron minimum) between your boat’s fuel
tank and outboard motor when using etha-
nol. Ethanol is known to allow moisture to be
absorbed into boat fuel tanks and systems.
Moisture in the fuel can cause corrosion of
metallic fuel system components, starting
and running complaints and require addition-
al fuel system maintenance.
