This is an off topic question, but some of you gents seem very knowledgable about diesels and I trust the technical competence of most of the contributers on this site. Also, I can't find anybody on the marine boatdiesel site who really know anything about the 6.5 engine.

I'm looking to replace the old 8.2T Detroit Diesels (250 hp) in my boat...basically same slug as used in 80's vintage school buses, etc. There's a company called Marine Diesel USA (www.marinedieselusa.com) in Oklahoma who claim their supercharged (not turbocharged) version of the basic 6.5 AM General diesel used in the military Hummer is the perfect solution...bolts in to original engine mounts, same transmission bolt pattern, available up to 400 horsepower/500+ ft-lb, fuel efficient, clean, lite weight, etc. The engine is much cheaper than Cummins, Detroit, Yanmar, etc. These guys claim the base military Hummer engine (produced by AM General, not GM) is a highly evolved version of the GM 6.5, and is in a much more capable service category than the GM unit used in civilan trucks/civilian Hummer...much heavier duty, etc. Anybody have knowledge of these guys or have background on the evolution of the 6.5 military Hummer engine? What about 400 hp from that engine in terms of durability expected in a boat....where the engines are worked very hard for long periods compared to street use? Are these guys blowing smoke? Thanks.

The updated AM General blocks are great, but they are big $$ unless you can find one used from someone who doesn't know their value.
The 400HP/500ftlbs numbers don't compute - that would either produce less HP or more torque. Those blocks have a higher nickel content and have thicker main webs in the block. Cheaper? Aren't those supercharged engines something like $10K?

Cowkiller, thanks for the site tip. Dieselsj, regarding cost, they're a whole lot cheaper than the marine cummins, detroit, etc....$30K for marine engine in that class seems typical.,,still insane. I don't understand why. I know they advertise 400 HP...the torque number was a for the 300hp version I think... I'm sure your right, the old 8.2s are 250 hp and around 500 ft-lbs. Thanks.

I'm new to the FSJ community (I've owned one for several years, but now am seriously interested in working on it) and like Knucklehead, I really want to stuff a diesel in my WarWagon. SJDiesel said it's doable with a 6.2 and would like to know how complicated it is to hook up the drivetrain. the Warwagon has a 727.

Go to Novak enterprises was look around. The 6.2, as I'm told, mounts up like a BB chevy which is like a SB chevy. Son you would need a bell chevy bellhousing and an adapter to go to you trans (if manual). Sorry I don't do auto, bI would assume that it would be best to get the complete motor to transfer case assembly. This would be fairly straight forward.
