EMISSIONS

Emissions Information

Manufacturer's Responsibility

Beginning with 1998 model year engines, manufacturers of all marine propulsion engines
must determine the exhaust emission levels for each engine horsepower family and certify
these engines with the United States Environmental Protection Agency (EPA). A certifica-
tion decal/emissions control information label, showing emission levels and engine specifi-
cations directly related to emissions, must be placed on each engine at the time of manufac-
ture.

Dealer Responsibility

When performing service on all 1998 and later outboards that carry a certification, attention
must be given to any adjustments that are made that affect emission levels.
Adjustments must be kept within published factory specifications.
Replacement or repair of any emission related component must be executed in a manner
that maintains emission levels within the prescribed certification standards.
Dealers are not to modify the engine in any manner that would alter the horsepower or allow
emission levels to exceed their predetermined factory specifications.
Exceptions include manufacturers prescribed changes, such as that for altitude adjust-
ments.

Owner Responsibility

The owner/operator is required to have engine maintenance performed to maintain emis-
sion levels within prescribed certification standards.
The owner/operator is not to modify the engine in any manner that would alter the horse-
power or allow emissions levels to exceed their predetermined factory specifications.
Exceptions:
Carburetor jets may be changed for high altitude use in accordance with factory rec-
ommendations.
Single engine exceptions may be allowed with permission from the EPA for racing
and testing.
