It's not uncommon to see the GM 6.2L V8 engine mated to a ZF transmission in a boat.  What is uncommon however, is to see this entire package hanging off the transom inside an outboard motor cowling!  This outboard engine was introduced at the Miami Boat show.  

The Outboard uses the standard GM 6.2L V8 engine.  It produces 557 HP for some big power!  ZF designed the transmission, and all the controls are "fly by wire" so there are no cables.  The outboard will also accept ZF's joystick for easy docking.  As these center consoles keep getting bigger and bigger, this engine really makes a lot of sense when you break down the numbers:

 (3x) Seven Marine 557's (4x) Yamaha 350's
 1671 hp 1400 hp
 3000 lb (~1000/ea) 3200 lb (~800/ea)
 ~$110000 ~$108000
