Emissions Information
Manufacturer’s Responsibility:
Beginning with 1998 model year engines, manufac-
turers of all marine propulsion engines must deter-
mine the exhaust emission levels for each engine
horsepower family and certify these engines with the
United States Environmental Protection Agency
(EPA). A certification decal/emissions control in-
formation label, showing emission levels and engine
specifications directly related to emissions, must be
placed on each engine at the time of manufacture.
Dealer Responsibility:
When performing service on all 1998 and later out-
boards 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 adjustments.
Owner Responsibility:
The owner/operator is required to have engine
maintenance performed to maintain emission levels
within prescribed certification standards.
The owner/operator is not to modify the engine in any
manner that would alter the horsepower or allow
emissions levels to exceed their predetermined
factory specifications.
Exceptions:
•
Carburetor jets may be changed for high altitude
use in accordance with factory
recommendations.
•
Single engine exceptions may be allowed with
permission from the EPA for racing and testing.
EPA Emission Regulations:
All new 1998 and later outboards manufactured by
Mercury Marine are certified to the United States
Environmental Protection Agency as conforming to
the requirements of the regulations for the control of
air pollution from new outboard motors. This
certification is contingent on certain adjustments
being set to factory standards. For this reason, the
factory procedure for servicing the product must be
strictly followed and, whenever practicable, returned
to the original intent of the design.
The responsibilities listed above are general and in
no way a complete listing of the rules and regulations
pertaining to the EPA laws on exhaust emissions for
marine products. For more detailed information on
