Suzuki Marine Leading the Way in Low-Emission Boating

At Suzuki Marine, environmental responsibility isn’t a marketing slogan—it’s the way we design, build, and deliver every outboard motor. For decades, we’ve led the marine industry in clean, efficient technology, pioneering the shift to four-stroke engines and embracing eco-conscious manufacturing to reduce our environmental footprint.
Today, every Suzuki four-stroke outboard not only meets but exceeds some of the world’s strictest emissions standards—earning the prestigious California Air Resources Board (CARB) 3-Star Ultra Low Emissions rating across the range. This means you can enjoy exceptional performance, fuel efficiency, and reliability while making a positive difference to the waters we love.

Why Suzuki Outboards Are Greener by Design

• CARB 3-Star Ultra Low Emissions Rating – Every Suzuki four-stroke outboard meets the gold standard for emissions, producing 65% fewer emissions than the EPA 2006 limit.
• EPA-Compliant Since 2006 – We’ve consistently met or exceeded U.S. Environmental Protection Agency standards for nearly two decades.
• Suzuki Lean Burn Technology – Our advanced fuel-air optimization system improves efficiency, cuts fuel consumption, and lowers CO₂ emissions.  Learn more 
• Eco-Friendly Manufacturing – We incorporate sustainable materials, minimize waste, and recycle wherever possible.
• Innovative Engineering – From fuel injection systems to catalytic converters, our technology ensures lower emissions without sacrificing performance.
  

  Understanding the CARB Rating System

  When choosing an outboard, knowing the CARB star rating helps you understand its environmental impact:

• ★ One Star – Low Emission
  Meets CARB 2001 exhaust emission standards, 75% cleaner than traditional carbureted two-strokes. Equivalent to U.S. EPA 2006 standards.
• ★★ Two Stars – Very Low Emission
  Meets CARB 2004 standards, producing 20% fewer emissions than One Star engines.
• ★★★ Three Stars – Ultra Low Emission
  The cleanest option—65% fewer emissions than EPA 2006 limits. Every Suzuki four-stroke outboard proudly carries this rating.

Cleaner Oceans, Same Suzuki Power
Boaters demand performance, and Suzuki delivers. Our low-emission outboards still provide the torque, speed, and reliability we’re known for—without the heavy environmental footprint.

If you regularly explore sensitive marine environments or want to reduce your boating impact, Suzuki is the smart, responsible choice.
