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.

Piston
It automatically sets
timing. It measures temperatures throughout the engine, as well as
ambient air temperature and barometric pressure.
Pressure
Relief Valve
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.
