Did the article indicate whether they were 2 stroke or 4? (inboard
diesels come in both varieties).

Hmmm.... from the website posted by Thunder, "16-Valve Direct Acting
Double Overhead Cam" so it must be a four stroke. I would have guesed
two stroke to save weight.

The "Great Slobering Beasts" from Detriot Diesel have four valves per cyl.
Just all are used for exaust. I could imagin a lobe that was able to pump
an injector at the proper firing time. I wonder where they plan to dump to
blower box oil that always drips like the Detroit that enabled it's
reference in the Bible.

I checked again last night, it's on page 34. The boat was a 22 foot
Glassmaster, weighted just under 3000 pounds. The fuel burn rate was 6
gph, the milage they gave was 5.6 mpg (I wish they would use knots
instead of miles) with full fuel. It sounded like their four cylinder,
four stroke, turbo charged engines. A two stroke is going to need a
blower of some kind for exhaust scavenging. I imagine it wouldn't be
very easy to cram a turbo, a blower, and the plumbing for the air
under a small outboard cover, if it were a two stroke. Also, with the
regulations going the way they are, if it were a two stroke, you
probably wouldn't be able to sell them a few years from now. It was
interesting, if they do what they claim to do, you could probably
throw a pair of 3.0's on a 25 foot center console, get the same kind
of speed, and probably burn like 10 gph. A day trip to the Hudson
Canyon, three hours out, three back, seven hours of trolling, probably
75 gallons of fuel, I would guess that's about half what you would
burn now with gas outboards. These guy's could be the future of
offshore fishing with the way fuel prices are. The only thing that
could kill them would be if the manufacturer got greedy, and wanted an
outragous amount of money for the engines.

I have a 3 liter ETEC 200 hp HO (90 degree block) that accomplishes
about the same fuel efficiency.

I'm also curious about their speed figures - did the article mention
what speeds were attained?

Why would you need both???

Unless Etech has actually found a way to do what they claim to be
doing (lower emissions than current four strokes). Might work for two
stroke diesels as well.

And you're happy with it so far I take it?
I talked with a dealer the other day and he says they haven't replaced
a power head yet (but I wouldn't expect him to tell me even if he
has).
Etechs haven't caught on around here yet but given the pro-OMC crowd
of the past in my area, I don't know why it shouldn't. We shall see.
