From Packard V12 Marine Engine

Contrary to popular belief the Packard V12 4M-2500 marine petrol engine did not start it's life as a licence built US made copy of the British Rolls Royce Merlin engine, this has been pointed out to me by various people and the historical evidence proves this, the Packard V12 1M 2500 engine was used extensively by Garr Wood in his world record holding speed boats of the 1930's and the licence built Merlins were not produced by Packard until well into the war years.
