The technology of Evinrude E-TEC is far more than an update of today's direct injection technology. Rather, it pulls from some of the best marine, automotive, and aerospace technologies, and applies them in ways that change the face of the outboard engine. In addition, some key structural components are borrowed from much larger engines, providing an amazing margin of durability, while holding down costs.
The "brain" of every E-TEC engine is its Engine Management Module (EMM), which can perform more than 8 million calculations every second. In fact, an E-TEC has been described as a very simple engine controlled by an extremely powerful computer.
It automatically sets timing. It measures temperatures throughout the engine, as well as ambient air temperature and barometric pressure.
The spark plugs feature double platinum tips, and provide a short spark at high RPM or a long spark start-up and idle - both intensities controlled by the EMM.
How does the E-TEC manage no break-in period? First, the cylinder bores are boron nitride-honed which exposes porosity in the cylinder alloy which actually retains a microscopic layer of oil to decrease initial wear. The EMM monitors the initial run time, adjusting oil delivery as required.
BRP also precision machines all parts to ensure perfect "mating." And during the life of the E-TEC, the exclusive E-Start system provides instantaneous starting, as direct light combustion eliminates the fuel wet-down period.
E-TEC Injector
The engine fires so quickly (within a single revolution), that it startles some! The EMM intensifies spark during cranking, and in the rope-start version, the injection system is independent of the battery, as it is magneto driven.
Evinrude E-TEC also allows for easy at-home customer winterization program. Attach a garden hose, follow the simple instructions in the owners manual, and in a few minutes, you're ready for winter - no expensive dealer trip necessary!
Winterization
The sealed fuel system minimizes oxidation during long-term storage, and there is no battery drain in the key-off mode. The "Sure-Dry" Air Intake System also prevents engine damage caused by water intrusion.
To ensure that the high-demands of quality were met, the Evinrude E-TEC was put through 30,000+ hours of testing, including field-testing and full factory testing.
