The article was in SWS..I had a typo 7.67 gal/hr @ 30mph...3.9 mpg range 540 miles.
IMO with the high price of big 4 strokes (and their short life span) vs the lowing costs of the new lighter weight deisels (ie yanmar's) (and thier longer life span), there is NO question that they are cheaper. A new yanmar diesel is about 35K for something in the 350-440 hp range. What do you think twin 225 4 stokes go for? If you walk away @ 35K you should be a happy man.
I am not a I/O fan but I would like to see more pump jets made. They have a higher eff at cruise and high speeds and a lower eff at speeds below cruise. For me that is ideal, I want to troll at a creep and fly @ cruise.
No matter I think the entire scout line has really improved the last few years and this is a step in the right direction.
