I thought this was an interesting review and explanation of the E-Tec. http://www.boatingworldonline.com/News.htm?CD=1044&ID=4034

Key sentence in the entire article for me is: "It has a magneto, so you can even pull start it if you have a battery problem." If that is true, and I think it is, that feature alone substantially sets this motor apart from every other clean motor made today, 2-stroke or 4-stroke.

Good article! Unbaised! A must read for those who are repowering or are buying a boat.

Kind of makes you think twice about big heavy 4 strokes with a million moving parts and significantly more maintenance. I hope their reliability is as good as it appears. It's the simplest design available from any manufacturer of clean engines. A reliable clean 2 stroke or a few different choices on 4 strokes. It's a good dilemma to have if you're repowering!

I have to admit that was the best writing explaining the difference between Ficht and E-TEC technology that I have seen. Anyone parroting the old just a Ficht with a new name, is just showing their ignorance.

quote:
The biggest difference between the E-TEC and its Ficht predecessor is the way it delivers fuel into the combustion chamber. The Ficht models — which Evinrude still offers in mid-range power — use an electromagnetically controlled piston to hammer the charge into position to be burned and use a spring to return it to its starting position. It has only two basic positions: inject or retract. In contrast, the E-TEC injector uses a voice coil, just like the one found at the back of your stereo speaker at home to control the injector. This gives it not only the ability to allow the amount of fuel being delivered to be varied, depending on the situation, but when the polarity is reversed, the injector piston is actively pulled back. The result is a system that eliminates that clackety sound made by Ficht injectors at low rpm, and is approximately twice as fast, allowing it to operate at a higher fuel pressure.[/quote}
Also, I'm not familiar with a Helmholtz Resonator, but it seems fairly unique. jimh, I defer to your backround on this one:
[quote]To further quiet the engine, molded foam cowling inner liner is used along with an idle air bypass and a newly designed piston assembly that reduces the sound of piston slap. A clever innovation called a Helmholtz resonator waits for a certain sound to occur, then produces a sound of the same wavelength and amplitude, but in the opposite phase, which in effect, cancels it out.
