Product Stewardship

2015 Goals

  • Reduce outboard emissions by more than 70% percent (between 2005 and 2015)
    • Transition from two-stroke to four-stroke technology
    • Offer 3-Star emissions on a broader range of engines
    • Promote more-sustainable products
  • Reduce sterndrive emissions by 60 percent (between 2005 and 2015)
    • Complete line of catalyzed engines
  • Launch 25 products that increase fuel efficiency
    • Create 25 products, each of which will increase fuel efficiency by at least 5 percent

2017 Goals

  • Reduce sterndrive emissions by 65%
  • Reduce outboard emissions by 74%
  • All new engines of 150hp and higher will have engine-maintenance-monitoring capability to provide extended service intervals
  • All new parts that are recyclable will have the correct recycle sign on them by 2017 or sooner


Mercury Marine is creating a line of products that enhance our environmental position and make boating more enjoyable. We will continue to develop products that reduce emissions, improve fuel efficiency, are made from higher content of recycled materials and have a greater ability to be recycled.


  • Integrate a product-impact scorecard that combines weighted averages in areas such as fuel efficiency, emissions, recyclability and composition of parts
  • Develop customer-focused product training that encourages fuel-efficient operation, low-impact refueling and proper disposal of waste
  • Continue cooperation with the California Air Resources Board (CARB), the Environmental Protection Agency (EPA) and international agencies to promote responsible and progressive emissions technology and standards


  • Mercury has:
    • Defined a supplier scorecard to measure key sustainability attributes, such as energy and water consumption, waste disposal, and recycling activities and initiatives.
    • Completed its first-ever supplier survey to collect data regarding key sustainability attributes, establish a baseline and create continuous business goals. Because different manufacturing processes offer different scales of opportunities, the resulting information will be studied and segmented according to business type. The survey will be conducted annually.
  • The emission certification level of the Mercury 150 FourStroke is 25% below that of the Verado 150hp.
  • Through product planning, operational practices, and resource conservation programs, Mercury Propellers is dedicated to continuous improvement in:
    • Developing new products that allow boaters to conserve natural resources through improved fuel efficiency.
    • Continuing research and development to design propellers that will meet the goal to develop products that will increase fuel economy by 5%.
150 Fourstroke
Mercury's 150 FourStroke - released late in 2011 - is light, compact, durable, quiet and fuel-efficient.
Trimmed Material
Mercury works with its dealers to help consumers select propellers that will best suit the boaters' intended use, providing best performance and fuel efficiency.
  • The Fuel Demand Valve by Attwood Marine (a Mercury company) received the 2013 West Marine Green Product of the Year award. The Fuel Demand Valve prevents fuel from being forced into the engine through the fuel line due to pressure in the tank, and provides fuel to the engine only when the engine demands it. The valve prevents engine flooding, fuel leaks and spillage. Mercury previously won the West Marine Green Product of the Year award for its fuelefficient ECO-Screen gauge.
  • The introduction of fuel injection and catalyst technology reduced hydrocarbons (HC) and nitrogen oxide emissions (NOx) by approximately 80% and carbon monoxide (CO) emissions by 50% in Mercury sterndrive and inboard engines.
  • Moving Prop Alert available for more Mercury engines.
  • Mercury outboard-engine technology has produced a dramatic reduction in exhaust emissions (combined HC+NOx) in all product categories:
    • 80% lower emissions from large outboards:
      • The current direct-fuel-injected two-stroke 150hp OptiMax and Four-Stroke Verado compared with traditional two-stroke Mercury 150hp engines.
  • Mercury implemented the use of RPET (Recycled Polyethylene Terephthalate) in clamshell packaging. RPET uses recycled plastic while allowing the packaging to be fully curbside recycled.
Lower Emissions, Improved Efficiency

With the advent of lower-emission OptiMax and Verado outboard engines, and the conversion of gasoline inboard and sterndrive engines to electronic fuel injection and exhaust catalysts, Mercury Marine has significantly reduced exhaust emissions and dramatically improved fuel economy with no loss in engine performance.

Eco Mode Becomes Standard on VesselView

Eco mode, previously an optional feature, now comes standard with VesselView 4 and VesselView 7 displays, which utilize advanced customer learning algorithms for optimized speed and trim set points to reduce fuel consumption.

Sound Control

The hemi-anechoic chamber ? or sound lab ? at Mercury Marine headquarters in Fond du Lac, Wisconsin, is used primarily for noise-source identification and the development of intake-silencing and exhaust-silencing systems. The lab enables Mercury engineers to target noise-control efforts and optimize sound quality in order to achieve world-class noise, vibration and harshness (NVH) characteristics in outboard engines.

Sustainability Contributions

Products, features and processes that illustrate Mercury Marine?s current sustainability efforts include:

  • Leveraging test engines across multiple projects
  • Utilization of electric motors for component-level validation
  • Increased use of Dacromet-plated fasteners in place of cadmium
