Ford 2715E (Dorset)

The Ford 2715E (commonly referred to as a member of the Dorset group of engines) was produced by Ford of Britain from October 1970 until ¿September? 1981 when production switched to the very similar 2725E (Dover Standard). It is a 120 horsepower, 380 cubic inch, parent bore, 6 cylinder, naturally aspirated, diesel engine which was originally designed to power British Ford D-Series lorries such as the one shown below. It was immediately preceded by a transition engine produced from November 1969 until October 1970 known as the 2704C that was almost identical to the 2715E except it had a slightly lower compression ratio of 15.5:1 verses 16:1 and was rated at slightly less horsepower of ¿108.5? hp verses 120 hp.

Ford D-Series Lorry

Some of these engines, like many of Ford of Britain’s diesel engines, were also fitted into tractors, rock crushers, harvesters, gensets, and other equipment by various manufactures around the world. Ford themselves never produced a marine version of this particular engine, however It became very popular, especially in Asian Trawlers, when marinized by Lehman and known as the Ford-Lehman 120 (6D380) below.

Primary Marinizers of Ford Industrial Power Diesel Engines

  • Lehman Mfg Co ⇐ SEE “Fixes” that need to be accomplished to prevent engine damage
  • American Marine Ltd (Mfr of Grand Banks)
  • Beta Marine
  • Bomac
  • Mermaid
  • Northeast Ford Engines Inc
  • Sabre
  • American Diesel Corp
    In 1981, Bob Smith, who was the former managing director of Lehman Power, founded American Diesel Corp in Kilmarnock, VA to  provide aftermarket marinizing replacement parts and support for Lehman marinized Ford Industrial Power (UK) Diesel engines. They also produced their own marinized replacement engine packages from the last of the Non-EPA Ford 6.22L (Ford Otosan) engines similar to the Ford-Lehman Super 135’s. They were first rated at 125 hp and then later at 140 hp.

The fuel injection pumps on later engines (1965+) were gear driven directly
without any exposed couplings or extension shafts (see below).

Lehman 4cylLehman marinized FORD 2701E with directly driven fuel injection pump.
Also note that the remote oil filter (which had been inverted for shipping) is now righted.
But “Two Shaft” Raw Water Pump has yet to be replaced with “Single Shaft” Pump to avoid shaft failure.
See other Lehman “Fixes” that need to be accomplished to prevent engine damage at Lehman Mfg Co.

NOTES: Produced 10/1970~?/1981? (See Ford Industrial Engine Production Dates by Serial Numbers by Jimcdbts). Data from Ford 2700 Series Service Manual (Dated 6/79) & Sabre Lehman OpManual. 6D380-W HP data from BoatDiesel, 6D380-C&P HP data from OpManual. Various data sources list slightly different B&S, Displacement, etc. Fitted with Simms Minimec P5130 Injection Pump, angle cut timing gears and pressed steel timing gear cover. This model powered Cargo lorries. This is the popular engine marinized by Lehman and known as the Lehman 120.

*This engine is equipped with a Simms Minimec mechanically governed mechanical jerk-type fuel injection pump. The 120 BHP output rating @ 2500 rpm is achieved when the engine is at full throttle and overloaded enough that the injection pump rack is fully advanced to maximum spray duration (ie when at WOT and under full overload while accelerating, climbing ocean swells, on a dyno or over-propped). This output rating is intended to provide the intermittent power needed during acceleration and when climbing ocean swells. If the propeller is properly pitched for the vessel, the engine may come close to this output during full throttle acceleration or when climbing ocean swells at WOT, but the engine was not intended to be operated under such overload for very long as this lugging of the engine is detrimental to the engine from overloading, hot-spots, over-fueling, incomplete combustion, and carbon buildup and wear. The vessel’s propeller pitch should be selected to allow the governor to draw back the injection rack to the ideal spray duration as the engine approaches 2500 rpm (which should produce roughly 114.5 BHP for this particular engine). The Mermaid Power Curve shown below is misleading as Ford says that the 120 HP is achieved only in ‘Overload’. IMPORTANT NOTE: The service life of an overloaded diesel engine will suffer considerably due to over-fueling, incomplete combustion, etc. Likewise the life of an under-worked diesel engine will also suffer, but in this case mainly from incomplete combustion that results from low combustion temperatures. The size and power output of any diesel engine and the propeller pitch must be matched to the vessel’s use, speed, hull type, and weight in order to maximize the engine’s service life. See Selecting the Right Diesel Engine for a Boat.

6 thoughts on “Ford 2715E

    1. Editor Post author

      The 2715E is a 380 cubic inch displacement parent bore engine and does not have replaceable cylinder liners. Ford never recommended that it be turbocharged. Neither Ford nor anyone else turbocharged this engine for resale.
      Without more information (year, model, etc.), I would suspect that the engine you’re more likely to be looking for is the similar, but more robust 363 (sometimes called 360) cubic inch engine which has replaceable cylinder liners and Ford did turbocharge as the 2704ET (1968-1981) and 2726T (1982-1991).
