[1] Five aero variants were produced, of which the 3A-2500 was the most numerous. All of a sudden, we had a 617 cubic inch engine, eight cubes less than that specified by the new rule. Bad ass. After the challenges were overcome, they had redesigned the engine patterns,upgraded the quality control and metallurgy standards and made many major changes that involved extensive redesign. Packard built the Rolls-Royce Merlin aero engine under license alongside the 4M-2500, but with the exception of the PT-9 prototype boat brought from England for Elco to examine and copy, the Merlin was never used in PTs. Driven by Indy Car star Ralph DePalma at the Daytona Measured Mile, a new record was established at 149.875 mph. Packard Automotive would supply engines to power Allied planes and maritime vessels, including the British Royal Air-force and U.S. PT Boats. Senior Packard management report that Jesse Vincent, Packards lead engineer, started on the 3M-2500 experimental engine in 1939 based on converting the Packard 2500 aircraft engine into a marine versionand seven were built for the U.S. Navy. . Since Autoweek is talking tolerance this week, it seemed like an opportune time to dig a little deeper into the Merlin storywhich, after all, is a big point of pride for Packard car owners like myself. Exactly, PT Boats used 3x 2500 series Packard V-12's rated from 1200 to 1850 HP. If there's a key to understanding Rolls-Royce's Merlin manufacturing tolerances, or the asserted lack thereof, it might be FordFord of Britain, that is. Packard, you see, was a lot more than just Knudsen's Plan B after Ford rejected the Merlin contract. While Packard was also commissioned to produce the excellent Merlin aircraft engines that powered the famous Supermarine Spitfire fighters of Britain, these were never actually used in ELCO PT boats - instead reserved for the overseas British aircraft demand.

The mistake here, and the foundation of the file-to-fit Rolls-Royce Merlin idea, is likely in conflating early engines, which were built in relatively limited quantities throughout the early to mid-1930s, with the mighty (and mightily improved) mass-produced Merlins that emerged as the war progressed. Fighter engines were very popular, particularly the Packard V-1650 Merlin engines, many of which were modified for air racing events such as the Thompson Trophy, Bendix Trophy and Cleveland Air Races.

Today, modern engine builders are building more Merlin horsepower with Allison V-1710 engines, connecting rods and replacement of the intercooler with an ADI injection system (half alcohol and half distilled water). So, the Vosper built Motor Torpedo Boats have a direct link to the American Auto Industry. Checking for missed updates.

The audio on this one is mangled. And even in those early years, Packard realized the importance of on-the-water motorsports and really supported it. This notion is also reflected in the March 1946 issue of Flying magazine, which includes a retrospective on the powerplant by Paul H.
