WASHINGTON, DC — CK Motorsports and Growth Energy released a new survey, which found that an overwhelming majority of American boaters are confident when selecting fuels. The poll of 500 U.S. boat owners conducted by Quadrant Strategies showed that 94 percent of boaters find it easy to pick the right fuel and are confident in their selection. “Critics of the ethanol industry often claim that offering higher ethanol blends would confuse boaters and cause misfuelling issues, but that is simply not the case,” said Keith Holmes, owner of CK Motorsports – a premier certified Mercury Marine Engine & Racing service dealer and Throttleman of the American Ethanol Cat Can Do Catamaran. “Ninety-seven percent of the nation’s fuel supply is E10 – gasoline that contains 10 percent ethanol – and all current boat engines are warrantied for E10 and have been for nearly two decades. Labels at the gas pump clearly indicate the ethanol content of the fuel, and boaters report that picking the right option is easy and worry free.” This labeling is mandated under federal law, as some small equipment and marine engines should only be fueled with E10. “Boaters appreciate that E10 is a high-performance, earth-friendly option embraced by the racing community and warrantied by marine manufacturers,” Growth Energy CEO Emily Skor said. “It is quite clear that boaters are making the right choice at the pump. From the roadways to the offshore powerboating events that Keith Holmes competes in, ethanol blends are providing great value to consumers.” Holmes, a veteran mechanic, has long been a source of expertise for policymakers, appearing last year on a Capitol Hill panel alongside other engine performance experts and professional fishermen to explain the importance of biofuels in protecting the environment, preserving America’s energy security, and providing a high-octane boost to boaters.

LAKE FOREST, Ill. March 1, 2017 - Brunswick Corporation (NYSE: BC) today announced that three employees have been selected among 130 recipients to receive the Women in Manufacturing STEP (Science, Technology, Engineering and Production) Ahead Award from the Manufacturing Institute for 2016.  Brunswick is among a handful of companies to have three recipients chosen for the prestigious award this year. The STEP Ahead Awards honor women who have demonstrated excellence and leadership in their careers and represent all levels of the manufacturing industry, from the factory-floor to the C suite.  Selected from Brunswick were the following: Morton is based in Merritt Island, Fla., while Vara and Weiss work in Fond du Lac, Wis. Morton and Weiss are among 100 women chosen as honorees of the STEP Ahead Award, while Vara was among 30 women designated as an "emerging leader." "We are extremely honored to have three of our colleagues chosen for this highly selective award," said Brunswick Chairman and Chief Executive Officer Mark Schwabero.  "They are truly a source of pride for Brunswick.  It speaks to the quality of our workforce and their dedication as well as the ultimate purpose of this recognition - to promote careers in manufacturing. "Manufacturers face the growing challenge of finding, engaging and advancing talent.  STEP Ahead raises awareness of these issues by showcasing opportunities and role models that can speak to the transformation of the industry - role models like Jan, Katelyn and Marcea," Schwabero continued.  "STEP Ahead celebrates and recognizes the accomplishments of outstanding leaders in manufacturing, inspiring the future generations of women leaders to consider full, enriching careers in manufacturing." Jan Morton began her career with Brunswick in 1984, working in the lamination department at the Company's sport boat manufacturing facility in Tennessee. Through the years, Morton was promoted throughout various functions in warehouse operations, purchasing, plant operations and sourcing.  Recently, Morton led a small team of sourcing professionals delivering several million dollars in cost savings. Katelyn Vara, an engineer, recently led a core team of about 12 engineers as well as coordinated with numerous other departments throughout Mercury and client boat companies to test and validate portions of Mercury Marine's totally new sterndrive marine engines.  A former college All-America volleyball player, Vara volunteers as an assistant coach at nearby University of Wisconsin - Oshkosh. Recently promoted to plant operations manager, Marcea Weiss continues to be a significant contributor to the overall success of Mercury Marine through her skills and participation and leadership in the Company's Lean Six Sigma (LSS) efforts worldwide.  Weiss is a certified Master Black Belt, one of the highest levels of certification, and led Brunswick's enterprise-wide Black Belt Council.  Weiss is also the commander and pilot for a MEDEVAC unit in the Wisconsin Army National Guard, where she flies UH-60 Blackhawk helicopters.  With her background, she has been a strong advocate of both Mercury's Veterans' and Women's Network. "These women exemplify the path an exciting career in manufacturing can take," said Heidi Alderman, 2017 Chair of STEP Ahead and senior vice president of Intermediates North America, BASF Corporation. "STEP Ahead recognizes women nationwide for their significant achievements to the field of manufacturing, and the positive impact on their companies and the industry as a whole." The STEP Ahead Awards are part of the larger STEP Ahead initiative, launched to examine and promote the role of women in the manufacturing industry through recognition, research, and leadership for attracting, advancing, and retaining strong female talent. A recent survey from Deloitte and the Manufacturing Institute found that six out of ten open skilled production positions are unfilled due to the talent shortage. Part of closing the skills gap means closing the gender gap, Alderman points out. On April 20, the Manufacturing Institute will recognize 130 recipients of the STEP Ahead Awards at a reception in Washington, D.C.  The STEP Ahead Awards program will highlight each honoree's story, including their leadership and accomplishments in manufacturing. ### About Brunswick Headquartered in Lake Forest, Ill., Brunswick Corporation's  leading consumer brands include Mercury and Mariner outboard engines; Mercury MerCruiser sterndrives and inboard engines; MotorGuide trolling motors; Attwood, Garelick and Whale marine parts and accessories; Land 'N' Sea, Kellogg Marine, Payne's Marine and BLA parts and accessories distributors; Bayliner, Boston Whaler, Brunswick Commercial and Government Products, Crestliner, Cypress Cay, Harris, Lowe, Lund, Meridian, Princecraft, Quicksilver, Rayglass, Sea Ray, Thunder Jet and Uttern; Life Fitness, Hammer Strength, Cybex, Indoor Cycling Group  and SCIFIT fitness equipment; InMovement products and services for productive well-being; and Brunswick billiards tables, accessories and game room furniture.

LAKE FOREST, Ill. Nov., 18, 2016 - Brunswick Corporation (NYSE: BC) announced today it has acquired the assets of Payne's Marine Group of Victoria, British Columbia, a leading wholesale distributor of marine parts and accessories (P&A) in Canada.  Terms of the transaction were not disclosed. Payne's had sales of approximately USD$17 million in 2015.  Payne's marine distribution business will become part of Brunswick's global P&A distribution business, which is operated by Brunswick's Mercury Marine division, based in Fond du Lac, Wis. With strategically located distribution facilities in British Columbia and Ontario, Payne's Marine provides broad geographic coverage as well as timely delivery services, technical expertise and support to customers across Canada.  It will be integrated into Mercury Marine's P&A distribution network in Canada, augmenting the presence of Mercury's Land 'N' Sea Canadian channels, particularly in Western Canada where Mercury Marine has made other recent investments, such as a new distribution center in Langley, British Columbia. "The two companies together will extend both the reach and value of our global P&A distribution network," explained Mercury Marine President John C. Pfeifer.  "Further, we believe leveraging the unique expertise of each operation will lead not only to cost and revenue synergies, but also will further accelerate our growth in the important Canadian marine market." "Our current strategy, as outlined at Brunswick's update to the financial community in November 2015, is to grow both our core marine and fitness businesses, while augmenting such growth through acquisitions primarily in fitness and marine P&A," explained Brunswick Chairman and Chief Executive Officer Mark D. Schwabero.  "This action continues the execution of that strategy, and marks the latest acquisition that we have made recently to expand our P&A distribution network's global reach into both segments and geographic areas that offer opportunity, following the acquisition of Bell Recreational Products Group in the Midwest, and BLA in Australia in 2014 and 2015, respectively." The Payne's Marine acquisition will have minimal impact upon Brunswick's 2016 results.

SAE International Journal of Engines | Year: 2012

A conceptual project aimed at understanding the fundamental design considerations concerning the implementation of catalyst systems on outboard marine engines was carried out by Mercury Marine, with the support of the California Air Resources Board. In order to keep a reasonable project scope, only electronic fuel injected four-stroke outboards were considered. While they represent a significant portion of the total number of outboard engines sold in the United States, carbureted four-strokes and direct injected two-strokes pose their own sets of design constraints and were considered to be outside the scope of this study. Recently, three-way catalyst based exhaust emissions aftertreatment systems have been introduced into series production on sterndrive and inboard marine spark ignition engines in North America. The integration of catalyst systems on outboards is much more challenging than on these other marine propulsion alternatives. Sterndrive and inboard engines are horizontal crankshaft engine derivatives of automotive products. Outboards on the other hand utilize a vertical crankshaft, open cooling systems, and consist almost entirely of components that were specifically designed for a marine outboard engine application. This report will show how Mercury Marine used state of the art processes and design analysis tools to successfully design a catalyst system for a production based outboard engine targeting combined hydrocarbon and oxides of nitrogen emissions performance equivalent to the sterndrive and inboard standard of 5 grams per kilowatt-hour over the marine engine emissions test cycle. Prototypes of the design were constructed and tested. Results of that testing will be shown that highlight the potential to meet future emissions requirements and some of the challenges that will face commercializing this technology.

Journal of Vibration and Acoustics, Transactions of the ASME | Year: 2015

Measurements are presented from a two-beam structure with several bolted interfaces in order to characterize the nonlinear damping introduced by the joints. The measurements (all at force levels below macroslip) reveal that each underlying mode of the structure is well approximated by a single degree-of-freedom (SDOF) system with a nonlinear mechanical joint. At low enough force levels, the measurements show dissipation that scales as the second power of the applied force, agreeing with theory for a linear viscously damped system. This is attributed to linear viscous behavior of the material and/or damping provided by the support structure. At larger force levels, the damping is observed to behave nonlinearly, suggesting that damping from the mechanical joints is dominant. A model is presented that captures these effects, consisting of a spring and viscous damping element in parallel with a four-parameter Iwan model. The parameters of this model are identified for each mode of the structure and comparisons suggest that the model captures the stiffness and damping accurately over a range of forcing levels.

FAST 2013 - 12th International Conference on Fast Sea Transportation | Year: 2013

Published model test results have shown a significant increase in propulsive efficiency for surface piercing marine propellers when they are operated at a yaw angle relative to the oncoming flow. This paper presents design and analysis work showing how this efficiency gain can be realized in a practical design. The implementation of yawed propellers is particularly suited to drive systems with a vertical shaft such as outboard motors and sterndrives. Surfacing propellers are known to produce substantial side forces. In addition to the efficiency gains from yawing the propeller and orienting the net thrust vector in the forward direction, there is a vessel control benefit to reducing or eliminating the side force produced by the drive system. This could lead to further performance improvement through reduced rudder size if the rudder is no longer required to balance the propeller side forces. Included in the paper are several design configurations utilizing yawed propellers as well as computational results showing performance gains as a function of yaw angle and submergence. Propeller geometry modifications, relative to non-yawed propellers, to accommodate the varying inflow direction to blade sections are considered as well.
