What head gasket does my mercury motor have??

I have a 1999 Mercury 150 XR6 "Bluewater Series" that the head gaskets recently failed. I've been searching for weeks and have been unsucessful. I've bought several incorrect gaskets (mostly incorrect cylinder sizes). Please help!

XR6 would be a 2.5L engine, if it has the original power head on it. 2.0 and 2.4 will bolt on.

Start here with your serial number. Double check the number on the welsch plug on top of the block behind the flywheel.
