E-TEC vs 4-STROKE - THE MYTHS EXPOSED...
The truth behind Evinrude E-TEC and 4-Stroke outboard engines:
Myth 1: "2006 EPA & EU legislations make 2-strokes illegal."
Fact 1:Evinrude is worldwide emissions compliant
With a fully stratified combustion system for an exceptionally cleaner boating environment, Evinrude E-TEC outboard engines comply with all EPA, CARB and EU standards, now and well into the future.
As reported by the EPA, Evinrude E-TEC outboard engines are cleaner than 4-strokes and much cleaner than any competitive 2-stroke DI models. In fact, Evinrude is the only DI engine approved for use on Lake Constance - the lake with the strictest environmental regulations in Europe.
Myth 2: "4-stroke engines are cleaner because 2-stroke outboards expel oil directly into the environment."
Fact 2: Evinrude engines have simply the cleanest outboard technology available.
Evinrude E-TEC engines were the first, and remain the only outboard technology to be honoured with the EPA's first Clean Air Excellence Award.
Evinrude E-TEC engines already show lower total reportable emissions than any other competitive engine, since oil in an E-TEC direct injection outboard is combusted in the cylinder. In fact, in reality, 4-stroke emissions need to be increased to account for the waste sump oil that is disposed of at the time of each service.
Myth 3: "4-strokes achieve the best fuel economy."
Fact 3: Evinrude gives you superior fuel efficiency.
Evinrude E-TEC provides economy without compromising power. The Engine Management Module (EMM) makes up to eight million calculations per second, delivering precisely the right amount of fuel needed directly into the combustion chamber and resulting in incredibly smooth, fast response and low fuel consumption, and the E-Start system ensures easy starts every time.
Myth 4: "4-stroke outboards require less maintenance than 2-strokes."
Fact 4: Evinrude outboards require the lowest maintenance.
Belts have always been the weak point of many competitive 4-stroke engines. The Evinrude E-TEC system gets rid of belts altogether, which means more time on the water and lower maintenance costs.
3 YEARS NO DEALER-SCHEDULED MAINTENANCE
Evinrude E-TEC outboard engines require no scheduled maintenance for the first three years or 300 hours, and not agian for three years after that. That's no oil changes and no belts to replace.
In fact, on average, the cost of servicing a 4-stroke outboard engine is three times more expensive than the cost of servicing an Evinrude E-TEC engine over this period.
Evinrude also gives you automatic winterisation and no spring tune-up. Compare that to 4-stroke engines which require an annual service, winterisation and de-winterisation.
Myth 5: "4-stroke outboard engines offer more torque than other outboard technologies."
Fact 5: Evinrude engines offer the best power to weight ratio in the industry.
Evinrude offers one of the best power-to-weight ratios in the industry, delivering better throttle response for quicker direction change and better torque and acceleration thanks to its lighter design. When it comes to torque, Evinrude E-TEC leaves 4-stroke rivals dead in the water. Whilst 4-strokes make a power stroke every other revolution of the crankshaft, Evinrude E-TEC makes a power stroke every revolution.
Myth 6: "4-stroke outboards are quieter than new DI 2-stroke engines."
Fact 6: No other outboard engine gives you a quieter boating experience than Evinrude.
Evinrude E-TEC's exclusive idle air bypass circuit, accoustically tuned intakes, exhaust silencers and 3-dimensional foam lining all result in major sound reduction, so your outboard engine sounds like nothing else on the water.
