Fuel blending varies by country and
region. Your outboard has been de-
signed to operate using the recom-
mended 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 operator's guide.
– Alcohol blended fuels attract and
hold moisture which may lead to
fuel phase separation and can re-
sult in engine performance prob-
lems or engine damage.
– Use of fuel containing alcohol
above the percentage specified by
government regulation can result
in the following problems in out-
board engines and fuel system
components
– Vapor lock or fuel starvation
– Starting and operating difficulties
– Deterioration of rubber or plastic
parts
28
– Corrosion of metal parts
– Damage to internal engine parts
– Have your dealer inspect for fuel
leaks or other fuel system abnor-
malities if you suspect the pres-
ence of alcohol in gasoline
exceeds the current government
regulation limits.

Use unleaded gasoline with an AKI (R
+M)/2 octane rating of 87, or an RON
octane rating of 91.

Biobutanol is a four-carbon alcohol
produced from renewable, plant-der-
ived energy sources in a fermentation
process similar to beer and wine pro-
duction. Biobutanol delivers more re-
newable energy content than ethanol
while remaining compatible with cur-
rent vehicles, boats, and infrastruc-
ture. 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 fitting, and fuel hoses.
Biobutanol blended fuel (either isobu-
tanol or n-butanol) may be used in all
Rotax E-TEC outboard engines. Use
of biobutanol blended fuel will NOT
void the warranty of your Rotax
E-TEC outboard engine.
Biobutanol blended fuel (Bu16 — up
to 16.1% by volume) has been ap-
proved for use by the National Marine
Manufacturers Association (NMMA).
