Author's note:  This page was added to the website in March 2016, with an update in March 2018.  The original information from 2016 and 2018 was based on information noted in "Our War Job," published by Delco-Remy in 1944.  Since 2018, I have learned considerably more from other research of other World War Two-era companies about the engines and ships in which Delco-Remy products were utilized.  The new Summary Table gives an overview of the engines, along with their associated watercraft, in which Delco-Remy parts were installed in during the war.  Tables 1-6 give more specific information on the different marine engines, and the boats and ships in which they were used.  The information below shows Delco-Remy electrical equipment along with supercharger blowers, pistons and other equipment were used at the forefront of naval warfare during World War Two.  Delco-Remy was in important factor in the winning of the naval war.  DDJ 4-22-2020

Delco-Remy Marine Equipment in World War Two from "Our War Job:"
 Thirty-eight models of generators, 11 models of regulators, 61 models of starting motors, eight models of ignition distributors and seven models of ignition coils; along with supercharger blowers for marine diesels, pistons for marine diesels with diameter of pistons ranging from 4 to 17 inches in diameter, diesel engine intake air pre-heaters, diesel engine fuel pre-heaters, diesel engine governor castings, and propeller pitch controls for sub-chasers and Landing Craft, Infantry (LCI) landing craft.

Packard 4M2500 Marine Engine:  One prominent and important use of Delco-Remy electrical equipment was for the Packard 4M2500 Marine Engine that was used on several types of high-speed watercraft.  The most famous of these boats was the American PT boat built by Higgins and Elco.  Each 4M2500 engine was equipped with a Delco-Remy starter, generator and voltage regulator.

There were 12,700 Packard 4M2500 marine engines built during World War Two.  For the small, fast PT and rescue boats of the war, the 4M2500 was the preferred engine.  This was because it could produce up to 1,500 hp in the later variants.  It was the most powerful of the gasoline powered engines of its type.  Table 1 below shows the known uses.  While Table 1 shows less than half of the engines being utilized in the known applications, at the start of World War Two, there were not enough of them to meet all of the demand.  Production could not keep up.  Therefore, several other types of engines were used in some of the same applications as other tables below will show.  The substitute engines also had Delco-Remy components.  No matter the which engine powered a fast motor torpedo or rescue boat, Delco-Remy was onboard.

The UK and Canada received 4,686 Packard engines during the war through either direct purchase or Lend-Lease.  With 12,700 total engines built, this left 8,014 for spares for US and USSR applications in PT boats and OEM engines in the various rescue boats built for both the Army Air Corps and the US Navy.



P-T 305 is only World War Two veteran Higgins-built PT boat still in existence.  It has been restored to operating condition and currently gives rides and tours.  The three Packard 4M2500 engines all have Delco-Remy electrical equipment on them.


Higgins Industries of New Orleans, LA built 201 PT boats during WWII, including PT-305 that served in the Mediterranean Theater of Operations.  PT-305 participated in 77 combat missions, sank three boats, and supported the Allied landings at Elba and Southern France.  The location of PT-305's boat house on Lake Pontchartrain on the north side of New Orleans is four miles from where she was manufactured in 1943.  Author's photo added 3-29-2018.


This is the starboard Packard 4M2500 engine in PT-305.  The Delco-Remy cranking motor and DC generator are plainly visible from the deck.  Author's photo added 3-31-2018.  The handle protruding from the rear of the engine is the transmission shift lever.  The transmission had three positions:  forward, neutral, and reverse.  Each engine had to be manually shifted by the mechanic in the engine room while the engine speed was controlled by the helmsmen.  Author's photo added 3-29-2018.

63-foot Rescue Boat P-619:


This 63-foot rescue boat built by the Miami Shipbuilding Company in December 1943 is now owned by Randy Cunningham of British Columbia.  It is powered by two Packard 4M2500 marine engines.  Due to the shortage of the Packard 4M2500, some of these boats were powered by the Hall-Scott Defender marine engine.  They had Delco-Remy 1111597 ignition assemblies.  See the Hall-Scott Defender section and Table 2 below.  Photo added 4-23-2020.


P-520 is an 85-foot Army Air Force rescue boat.  It was built in 1944 by the Wilmington Boat Works of Wilmington, CA and is powered by two Packard 4M2500 marine engines.   Some of these boats were powered by the Hall-Scott Defender marine engine as shown in Table 2 below.  Photo added 4-23-2020.

Packard 4M2500 Marine Engines with Delco-Remy DC generators and starters:


 The first display a visitor encounters when entering John E. Kushner Restoration Pavilion at the National WWII Museum in New Orleans, LA is this cutaway of a Packard 4M2500 marine engine.  The Delco-Remy cranking motor on the engine is prominently visible from the entrance of the building.  In September 2017, the National WWII Museum was ranked the number two museum in both the USA and the world by TripAdvisor Traveler's Choice.  Visitors from around the world see the Packard cutaway with its prominently displayed D-R cranking motor.  Author's photo added 3-29-2018.


All the visitors that view the engine at one of the world's most visited museums will see the Delco-Remy naval starter and its distinctive oval D-R tag.  Author's photo added 3-29-2018.


The starter is model 824 and has serial number 8904.  Author's photo added 3-29-2018.


This Delco-Remy DC generator is located on the opposite side of the Packard engine.  While not as easy to see, the D-R tag is still identifiable.  Author's photo added 3-29-2018.


One can actually see the Delco-Remy DC generator on the Packard engine through the window.  With all of the reflections from the glass the generator is somewhat obscured, but it and the D-R tag are identifiable as such. Author's photo added 3-29-2018.

Eleven 104-foot rescue boats were outfitted with Hall-Scott Defender engines.  A few had four Kermath Sea Raider engines with Delco-Remy starters, DC generators, regulators, coils and distributors.  No matter which engine was used in the boat, Delco-Remy electrical components were installed.  This model is on display at the National Museum of the United States Air Force.  Photo added 4-23-2020.

Hall-Scott / Hudson Motor Car Company Invader Marine EngineHall-Scott of Berkeley, CA built 1,692 Invader Marine Engines in 1942, which it designed several years earlier.  Due to lack of production capacity, the manufacture of the Invader engine was then turned over to the Hudson Motor Car Company which built another 4,000.  All Invader engines had Delco-Remy distributors, coils, voltage regulators, starters and DC generators.

Table 4 - Invader Engine usage in small boats during World War Two
Hall-Scott and Hudson produced 5,692 Invader engines during World War Two.  These 5,692 engines were used in the following applications.
Hall-Scott Invader engines, along with several other type engines, were specified for the LCP(L), LCV and LCVP landing craft.  However, the U.S. Navy preferred diesel engines.  So, the Gray Marine/Detroit Diesel 6-71 engine became the standard engine for these type landing craft.  When there were insufficient diesels to meet all of the needs of the military, because it was used in Sherman tanks and Wolverine tank destroyers, Hall-Scott/Hudson Invader and the other gasoline powered engines were substituted.

As far as Delco-Remy was concerned, it didn't matter whether the boats had Invader or 6-71s installed.  Both had D-R components.

The historical record is unclear on how many of the boats below were equipped with the Invader engine.

A Hudson Invader marine engine comes off the assembly line in Detroit during World War Two.  Delco-Remy supplied the electrical equipment for the 4,000 engines built.  The Remy starting motor and solenoid are visible in this photo.  The voltage regulator is the rectangular box to the right of the starter.  It would make sense for this to be a Remy unit.  However, the name on the regulator is Hudson Motor Car Company.  It could be Delco-Remy was under a contractual agreement to cast Hudson's name into the die cast cover. 


This contemporary photo of an Invader engine was taken at the Ypsilanti Automotive Heritage Museum shows the starter and solenoid.  Note the upside down triangle in the voltage regulator.  Author's photo.

Gray Marine 64HN9/Detroit Diesel 6-71 Marine Engine:  This engine was the marine version of the Detroit Diesel Division of General Motors 6-71 six-cylinder 225 h.p. engine.  Detroit Diesel built up the engine, tested it, and then shipped it to Gray Marine in Detroit.  It then added all of the necessary equipment for marine operation in landing craft.  This included but was not limited to adding a heat exchanger and transmission.  Because Gray was the last company to work on the engine, it is normally known as the Gray Marine 64HN9.  However, because Detroit Diesel supplied the base engine, I make note of its important contribution by denoting it as the Gray Marine 84HN9/Detroit Diesel 6-71.  Like the Packard 4M2500 marine engine, it was in high demand with a limited supply, and was the preferred engine for American landing craft during World War Two. 

The table below summarizes the number of World War Two landing craft built with Detroit Diesel Division of GM engines.  The 43,060 diesel powered landing craft were equipped with a total of 57,189 6-71 engines, each using a Remy starter, generator, voltage regulator and supercharger blower.  Delco-Remy also cast pistons for Detroit Diesel, and they were used in the landing craft engines.

525 of the 1,051 Landing Ships, Tanks, or LSTs built during World War Two were powered by two Electro-Motive Model 12-567 900 h.p. engines.  Each LST with an Electro-Motive 12-567 engine had a Delco-Remy Model 902(CW) or 903(CCW) cranking motor to start it.  For more on this subject please visit my page:   LST393


This is the size of the Delco-Remy 902 cranking motor compared to my size 9-1/2 shoe.  Author's photo added 4-23-2020.

The LSTs with the Electro-Motive 12-567 propulsion engines also used three Detroit Diesel 6-71 engines to provide for ship's power.  These engines had Delco-Remy starters on these engines.  Pistons for the two Electro-Motive Division of GM propulsion engines were cast in DR plant 5.  Author's photo.
