No doubt the 2 strokes are more powerful. Evinrude / Johnson needs to compare their etech's to othe two strokes as well. I think you will find the Mercury OPTIMAX motors outperform the etech's if you can believe the factory performance numbers.

Johnson/Evinrude lost most of their fan base when they went tits up a few years back and now they are flooding late night tv with infomercials that dont prove a thing to me because you can do anything on tv. If they really want to get their fan base back they should get their etech's out in the market by offering them at a more competitive price and then the owners word of mouth advertising will take care of the rest if they are really that good. The etech's are very expensive considering they are trying to get BACK their fan base IMHO.
