Regulations for Emissions from Marine Spark-Ignition Engines
EPA standards for exhaust and evaporative emissions reduce the environmental impact from marine spark-ignition engines and vessels. The emission standards require manufacturers to control exhaust emissions from the engines and evaporative emissions from fuel tanks and fuel lines. This page provides general information for consumers, boaters, and other users of marine vessels that use gasoline engines (or other spark-ignition engines). There are also links to the related regulations and supporting documents.
See the Electronic Code of Federal Regulations (e-CFR) for the full text of current regulations that apply to marine SI engines.
