EPA Emissions Regulations
All new 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 set to factory standards. For this
reason, the factory procedure for servicing the product must be
strictly followed and, wherever practicable, returned to the original
intent of the design. Maintenance, replacement, or repair of the
emission control devices and systems may be performed by
any marine spark ignition (SI) engine repair establishment or
individual.
EMISSION CERTIFICATION LABEL
An emission certification label, showing emission levels and
engine specifications directly related to emissions, is placed on the
engine at time of manufacture.
