QSB5.9-480 HO Marine Application(s)
I am planning on buying a new boat soon. Cummins powered of course!
2x QSB5.9-480 HO engines seems to be an awesome propulsion:

Obviously, this engine has a lot in common with our 5.9l RAMs...
I was wondering if they use better components in a 480hp marine engine for reliability (compared to our truck engine)? Like different pistons, etc.

That exceptional fuel efficiency is largely the product of a pair of new-for-2009 turbocharged diesel engines from Cummins-MerCruiser attached to Mercury Racing NXT1 drives. Dubbed QSB 5.9, the 480-horsepower diesel engine is significantly lighter than the original Cummins 5.9 model, which also developed 480 hp.
“Basically, Cummins took their 5.9-liter truck motor and marinized it,” said Jake Fraleigh, sales manager for Eliminator Boats. “And the drives have a special saltwater protection application on them.

I guess that explains something... but how can they make it lighter and yet add hp and torque, while remaining reliability?
