Fuel Requirements - BRP Evinrude E-TEC 40 Operator's Manual

Fuel Requirements

WARNING
Gasoline is extremely flammable and
highly explosive under certain condi-
tions. Follow the instructions in this sec-
tion explicitly. Improper handling of fuel
could result in property damage, serious
injury or death.
Leaking fuel is a fire and explosion haz-
ard. All parts in the fuel system should
be inspected frequently and replaced if
signs of deterioration or leakage are
found. Inspect the fuel system each time
you refuel, each time you remove the
engine cover and annually.
NOTICE
Always use fresh gasoline. Gasoline will
oxidize; the result is loss of octane, vola-
tile compounds, and the production of
gum and varnish deposits which can
damage the fuel system.
Fuel blending varies by country and region.
Your outboard has been designed to operate
using the recommended fuels; however, be
aware of the following:
• The boat's fuel system may have different
requirements regarding the use of alcohol
fuels. Refer to the boat's owner guide.
• Alcohol blended fuels attract and hold mois-
ture which may lead to fuel phase separa-
tion and can result in engine performance
problems or engine damage.
• Use of fuel containing alcohol above the
percentage specified by government regu-
lation can result in the following problems in
outboard engines and fuel system compo-
nents:
• Vapor lock or fuel starvation
• Starting and operating difficulties
• Deterioration of rubber or plastic parts
• Corrosion of metal parts
• Damage to internal engine parts
• Have your dealer inspect for fuel leaks or
other fuel system abnormalities if you sus-
pect the presence of alcohol in gasoline ex-
ceeds the current government regulation
limits.
Recommended Fuel: Use unleaded gaso-
line with an AKI (R+M)/2 octane rating of 87,
or an RON octane rating of 90.
Biobutanol (Bu16) Fuel
Biobutanol is a four-carbon alcohol produced
from renewable, plant-derived energy sourc-
es in a fermentation process similar to beer
and wine production. Biobutanol delivers
more renewable energy content than ethanol
while remaining compatible with current vehi-
cles, boats, and infrastructure. Biobutanol
does not phase separate in the presence of
water like ethanol and is less corrosive to fuel
system components such as fuel tanks, fuel
fittings and fuel hoses.
Biobutanol blended fuel (either isobutanol or
n-butanol) may be used in all Evinrude out-
boards. Use of biobutanol blended fuel will
NOT void the warranty of Evinrude outboards.
Biobutanol blended fuel (Bu16 - up to 16.1%
by volume) has been approved for use by the
National Marine Manufacturers Association
(NMMA).
Use in North America
NOTICE
NOT
Do use fuel from fuel pumps
labeled E85. Never experiment with other
fuels.
The use of unleaded gasoline containing al-
cohol above the percentage specified by gov-
ernment regulations is not recommended.
Use of fuel labeled E15 is prohibited by U.S.
EPA Regulations.
Use of a boat mounted water separating fuel
filter is strongly recommended.
Use Outside North America
The use of unleaded gasoline containing al-
cohol above the percentage specified by local
government regulations is not recommended.
Use of a boat mounted water separating fuel
filter is strongly recommended.
