The first opposing piston engines were built at least 1 century ago, they are now coming back up to date.
For my part, I sailed on a merchant ship, about 45 years ago, whose engine was with opposite pistons.
It was a 4-cylinder propulsion engine of approximately 5000 CV.
You can see a little documentation on these Doxford marine engines on the links below:
