Spark-Ignition Marine Watercraft - Regulatory History
In 2015 Evaporative Emission Regulations were put into place as well as test procedures to test evaporative emissions produced by Spark-Ignition Marine Watercraft.
In 2011 the California Exhaust Emission Standards and Test Procedures for 2001 Model Year and Later Spark-Ignition Marine Engines were amended to harmonize with the U.S. EPA and maintain the stringency of the tests.
In 2008 the Board relaxed exhaust emissions standards. To offset the increase in allowable emissions, small boat manufacturers were required to install carbon canisters on watercraft with high performance engines.
In 2005 the Board allowed additional time for manufacturers to comply with the new more stringent exhaust emissions standards.
2001 - 2002
In 2002 the Board implemented exhaust emissions standards and required that On-Board Diagnostics be included in stern drive and inboard powered watercraft.
In 2000 the Board implemented labeling rules which require that watercraft have a hang tag explaining the emissions equipment that is installed.
