Here are their various offerings. http://www.gm.com/explore/technology/gmpowertrain/engines/specialized/marine/marine_engines.jsp
and here is the LY6 offering http://www.gm.com/explore/technolog...s/specialized/marine/2008_6000_LY6_Marine.pdf
This engine puts out 385 HP and has 400 lb-ft of torque. While not quite as powerfull as the big block motor, it looks like a good choice to me. I wonder who GM sells this engine to if Mercury doesn't use it?
