Fuel consumption

You are kidding, right? If I look at a fuel consumption curve for an old NA DD engine, more or less the same engine as the old Grey Marine, I get 16-17 hp per gph. Virtually all modern common rail engines produce 19-20 hp per gph.

And they are lighter, run clean, don't burn oil, make much less noise, and meet Tier 3 emissions standards which the DD never will.
