ENOM00034-A
EPA pressurized portable
fuel tank requirements
EQUIPPED FOR UNITED STATES AND
CANADA MODEL
The Environmental Protection Agency
(EPA) required portable fuel systems that
are produced after January 1, 2011 for use
with outboard engines to remain fully
sealed (pressurized) up to 34.4 kPa (5.0
psi). These tanks may contain the follow-
ing:
An air inlet that opens to allow air to
enter as the fuel is drawn out of the
tank.
An air outlet that opens (vents) to the
atmosphere if pressure exceeds 34.4
kPa (5.0 psi). A hissing noise may be
heard as the tank vents to the atmo-
sphere. This is normal.
When installing the fuel tank cap, turn
the cap to the right until you hear two
clicks. This signals that the fuel cap is
fully seated. A built-in device prevents
overtightening.
The fuel tank has a manual vent screw
which should be closed for transporta-
tion and full open for operation and
cap removal.
Since sealed fuel tanks are not openly
vented, they will expand and contract as
the fuel expands and contracts during
heating and cooling cycles of the outside
air. This is normal.
EMISSION CONTROL SYSTEM INFORMATION
ENOM01008-0
Star label
This outboard motor is labeled with the
California Air Resources Board (CARB)
star label. A description of this label is
presented below.
ENOM01009-0
One Star-Low Emission
One Star- Low emission The one-star
label identifies engines that meet the Air
Resources Board's Personal Watercraft
and Out board marine engine 2001
exhaust emission standards.
Engines meeting these standards have
75% lower emissions than conventional
carbureted two-stroke engines.
These engines are equivalent to the U.S.
EPA's 2006 standards for marine engines.
