TECHNICAL INFORMATION
One Star
Low
Emission
The one-star label identifies engines that meet the Air Resources Board’s
Personal Watercraft and Outboard marine engine 2001 exhaust emission
standards. Engines meeting these standards have 75% lower emissions than
conventional carbureted two-stroke engines. These engines are equivalent to
the U.S. EPA’s 2006 standards for marine engines.
Two Stars
Very Low
Emission
The two-star label identifies engines that meet the Air Resources Board’s
Personal Watercraft and Outboard marine engine 2004 exhaust emission
standards. Engines meeting these standards have 20% lower emissions than
One Star-Low Emission engines.
Three Stars
Ultra Low
Emission
The three-star label identifies engines that meet the Air Resources Board’s
Personal Watercraft and Outboard marine engine 2008 exhaust emission
standards or the Sterndrive and Inboard marine engine 2003-2008 exhaust
emission standards. Engines meeting these standards have 65% lower
emissions than One Star-Low Emission engines.
Four Stars
Super Ultra
Low Emission
The four-star label identifies engines that meet the Air Resources Board’s
Sterndrive and Inboard marine engine 2009 exhaust emission standards.
Personal Watercraft and Outboard marine engines may also comply with these
standards. Engines meeting these standards have 90% lower emissions than
One Star-Low Emission engines.
