While the measure will initially target only certain types of engines still to be determined, the National Marine Manufacturers Association (NMMA) says the rule will match the same limits for hydrocarbons, nitrogen oxides, particulate matter, and carbon monoxide that the commercial diesel engine industry currently adheres to.
The NMMA has, however, expressed concerns that engine makers will have to compromise performance and add weight to current diesel engine models. But the EPA has suggested that engine builders tap the latest technology to lower emissions, including turbochargers, seawater cooling systems, and electronic fuel injection.
Most builders already use these technologies in their engines, but their primary motivation has been to boost power, not to cut down emissions. The NMMA's main argument against compromising engine power is that it will put U.S. builders at a disadvantage in overseas markets.
The EPA is also currently reviewing a separate proposal to regulate emissions from gasoline stern-drive engines.
