There's no real argument with that statement, is there?

Yes there is - after all, this is rec.bots - standard operating
procedure. :)

While I agree that you would almost have to swap engines on the same
boat to make it absolutely "scientific", you can compare, or make some
pretty good estimates, of what fuel consumption would be even
comparing results from different engines on different boats.

And I'm saying that ETEC will provide a significant increase in fuel
efficiency, both short term and long term, over any four stroke design
available today. In other words, given the mileage/idle/cruise/WOT
time on that same trip, I'm saying that your boat would have used more
fuel and cost more to run than mine.

That's my story and I'm sticking to it. :)
