I looked at new outboards last fall. If I had decided to buy a NEW one, it would have been the E-Tech for sure. Better fuel economy and lower maintainence costs than the Johnson. Much lower weight than Mercury or any 4 stroke for the same output. Just as clean as a 4 stroke. Plus a major "cool" factor to me.
But I wound up with a used Mercury for a fraction of the cost of the E-Tech, so what do I know
Maybe someday I'll put my money where my mouth is and actually buy one!
