In today’s world, where sustainability and environmental protection are more important than ever, Baudouin is pleased to announce that our 6F21 marine engine has successfully obtained the U.S. Environmental Protection Agency (EPA) Tier 3 certification. This marks a significant step forward in our commitment to providing sustainable, high-performance marine solutions. This certification not only demonstrates our steadfast commitment to environmental standards but also strengthens Baudouin’s position as a leader in clean marine technology.

EPA Tier 3 Certification: Setting the Standard for Cleaner Marine Engines

The EPA Tier 3 emission standards aim to significantly reduce harmful emissions from marine engines, including Nitrogen Oxides (NOx), Particulate Matter (PM), Hydrocarbons (HC), and Carbon Monoxide (CO). Achieving this certification for the 6F21 engine required the integration of advanced emission control technologies, effectively reducing pollutants without compromising the engine’s robust performance.

For Baudouin, obtaining Tier 3 certification is a crucial milestone in our drive towards a cleaner marine industry. Our certified engine range, including the 6F21 and 6M33.3, represents the forefront of clean marine solutions, meeting both operational needs and environmental requirements.
