Evinrude outboards produce two-stroke direct-injected engines ranging from 25 hp (19 kW) to a 3.4L V6 300 hp. They used carburetors until the late 1990s when EPA clean air regulations mandated new technologies. OMC partnered with FICHT of Germany to introduce direct injection. Extensive and thorough durability testing took place to assess the rigor and longevity of the design but the first design did not pass testing standards.
Initial production of the first design started prior to another round of EPA regulations. At the beginning, the company tried retrofitting the previous design in order to bring the motors up to the new standards. These modifications were not carefully engineered or designed and caused significant engine failures, most notably the powerhead failure. This eventually resulted in a recall of that generation of motors. The losses on these motors, the loss of reputation and the surge of competition from Japan and Mercury pushed the company into bankruptcy in 2000.
In 2001, Bombardier acquired the Evinrude and Johnson Outboards brands; the FICHT technology was reengineered into E-TEC direct injection. This improved fuel efficiency and reduced emissions, oil consumption, noise levels and maintenance needs. This is due in part to a pin-point oiling system which only applies oil to the necessary components, unlike the original two stroke motors. Evinrude E-TEC was the first outboard engine technology to win the US Environmental Protection Agency's 2004 Clean Air Excellence Award which recognizes low emission levels.[1]
All modern Evinrude motors were built and assembled in Sturtevant, Wisconsin, south of Milwaukee.
