Perkins 4.4 Engine Overview
The Perkins 4.4 is a four-cylinder diesel engine platform used in marine auxiliary and power-generation applications.
The engine family has a displacement of approximately 4.4 litres, with a 105 mm cylinder bore and 127 mm piston stroke.
Marine auxiliary versions of the Perkins 4.4 platform have been produced in naturally aspirated, turbocharged and turbocharged/intercooled configurations.
This allows the 4.4 platform to support different power requirements while retaining the principal cylinder dimensions of the engine family.
Depending on the individual engine model and generator configuration, Perkins 4.4 marine engines can operate at 1500 or 1800 rpm, making them suitable for common marine generator applications.
The exact power output, aspiration system, cooling arrangement, fuel equipment and installed components depend on the individual engine designation.
For this reason, a request simply stating:
“Perkins 4.4 parts”
may not provide enough information to identify the correct replacement component.
Always provide the complete engine model, such as 4.4GM, 4.4TGM, 4.4TWGM or 4.4TW2GM, together with the engine serial number.
Perkins 4.4 Technical Specifications
The principal specifications shared across the Perkins 4.4 marine auxiliary family include:
SpecificationPerkins 4.4Engine type4-stroke dieselCylinder configuration4-cylinder inlineDisplacementApprox. 4.4 litresCylinder bore105 mmPiston stroke127 mmFuel systemDirect injectionCooling systemLiquid cooledRated speeds1500 / 1800 rpm on applicable versionsAspirationNaturally aspirated / turbocharged / turbocharged-intercooled depending on modelPrimary applicationsMarine auxiliary and generator sets
Exact output, dimensions, weight, compression ratio and other specifications vary according to the individual Perkins 4.4 engine configuration.
Always use the complete engine designation and serial number when checking technical data or ordering replacement components.
Perkins 4.4 Marine Engine Models
The Perkins 4.4 marine auxiliary family includes several different engine configurations.
Although these engines share the same general 4.4-litre platform, differences in aspiration, cooling equipment, fuel-system specification and engine installation mean that parts should not automatically be assumed to interchange.
Perkins 4.4GM
The Perkins 4.4GM is the naturally aspirated version of the 4.4 marine auxiliary engine.
It uses the basic four-cylinder 4.4-litre architecture without a turbocharger and is used primarily for marine generator and auxiliary power applications.
The 4.4GM is rated for operation at 1500 or 1800 rpm, depending on the generator configuration.
For detailed specifications, applications, maintenance components and available spares, visit our Perkins 4.4GM Marine Engine Parts page.
Perkins 4.4TGM
The Perkins 4.4TGM is a turbocharged configuration of the Perkins 4.4 marine auxiliary engine.
Turbocharging allows the engine to provide greater power than the naturally aspirated 4.4GM while retaining the principal dimensions of the 4.4-litre platform.
Because of the turbocharger and associated air and exhaust systems, components should not automatically be assumed to interchange with those used on the 4.4GM.
Always identify the engine as 4.4TGM when requesting fuel, air, exhaust, cooling or internal engine components.
Perkins 4.4TWGM
The Perkins 4.4TWGM is another configuration within the Perkins 4.4 marine auxiliary engine family.
Its aspiration and associated cooling arrangement distinguish it from the naturally aspirated 4.4GM and other configurations within the family.
Parts associated with the air-intake, exhaust, cooling and fuel systems can therefore differ.
When requesting parts for this engine, provide the complete 4.4TWGM designation, engine serial number and existing component number.
Perkins 4.4TW2GM
The Perkins 4.4TW2GM is another marine auxiliary configuration based on the Perkins 4.4 platform.
As with other members of the 4.4 family, individual components can vary according to engine specification, production revision and generator installation.
The complete 4.4TW2GM engine designation and serial number should therefore be used when identifying replacement components.
Perkins 4.4 Spare Parts & Components
Alfa Marine Spare Parts can source a broad selection of Perkins 4.4 engine parts for routine service, corrective maintenance and planned overhaul work.
Parts requirements can range from filters, belts and gaskets to fuel-system components, cooling parts, water pumps and complete internal engine overhaul requirements.
The exact component should always be verified against the individual engine model and serial number.
Perkins 4.4 Cylinder & Internal Engine Parts
Internal engine components are critical for maintaining compression, combustion efficiency and reliable engine operation.
We can assist with:
- Pistons
- Piston rings
- Piston pins

Perkins 4.4 Water Pumps
Water pumps are among the commonly requested components for the Perkins 4.4 engine family.
Depending on the engine and installation, the required component may be a:
Fresh-water pump
Auxiliary water pump
or an applicable:
Raw-water pump
These pumps perform different functions within the engine cooling system and should not automatically be treated as interchangeable.
When requesting a Perkins 4.4 water pump, send:
Engine model + engine serial number + existing pump part number + photographs when available
This is particularly important when the vessel has additional marinisation or generator cooling equipment.

Common Perkins 4.4 maintenance requirements can include:
- Engine oil filters
- Fuel filters
- Fuel/water separator elements
- Air filters
- Belts
- Thermostats
- Gaskets
- O-rings
- Sealing washers
- Cooling hoses
- Maintenance kits
Filter references can vary according to the engine model and installation.
Always verify the existing filter number before ordering whenever possible.
Perkins 4.4 Turbocharger Parts
Turbocharged members of the Perkins 4.4 marine family require additional air and exhaust-system components that are not used on the naturally aspirated 4.4GM.
Depending on the exact engine model, requirements can include:
- Complete turbochargers
- Turbocharger cartridges
- Turbocharger gasket sets
- Oil feed components
- Oil drain components
- Air-intake hoses
- Exhaust connections
- Mounting gaskets
- Associated seals
A turbocharger should always be identified using the complete engine designation and turbocharger identification number.
Do not assume that every turbocharged Perkins 4.4 engine uses the same turbocharger.

Airflow and exhaust components differ according to the aspiration system fitted to the engine.
Requirements can include:
- Air filters
- Air-intake pipes
- Air hoses
- Intake manifolds
- Exhaust manifolds
- Exhaust gaskets
- Turbocharger connections
- Charge-air components on applicable engines
- Clamps
- Seals

Perkins 4.4 Marine Generator Applications
The Perkins 4.4 marine engine family is used primarily for auxiliary and onboard power-generation applications.
Depending on the exact engine configuration, installations can be found aboard:
- Commercial vessels
- Workboats
- Fishing vessels
- Offshore vessels
- Service vessels
- Yachts
- Superyachts
- Harbour craft
- Marine generator sets
- Auxiliary power installations
Applicable marine auxiliary versions can operate at 1500 or 1800 rpm, depending on the generator configuration and required electrical frequency.
The generator manufacturer, alternator and vessel installation can introduce additional components that are not part of the base Perkins engine.
Perkins 4.4 Parts Identification
Correct engine identification is essential when ordering Perkins 4.4 spare parts.
Do not rely only on:
“Perkins 4.4 engine”
Instead, determine the complete engine designation.
For example:
Perkins 4.4GM
Perkins 4.4TGM
Perkins 4.4TWGM
Perkins 4.4TW2GM
Then provide:
Complete engine model
Engine serial number
Existing part number
Part description
Required quantity
Photographs of the engine identification plate and existing component can also help with identification.
This is especially important for fuel injection equipment, water pumps, turbochargers, electrical components and major internal engine parts.
Perkins 4.4GM vs 4.4TGM
One of the most important distinctions within the Perkins 4.4 marine family is between the 4.4GM and 4.4TGM.
Engine ModelAspirationPerkins 4.4GMNaturally aspiratedPerkins 4.4TGMTurbocharged
The turbocharged engine uses additional air-intake and exhaust components and operates at different performance levels.
Parts should therefore not automatically be transferred from one model to another simply because both engines belong to the Perkins 4.4 family.
For detailed information about the naturally aspirated model, visit our Perkins 4.4GM Marine Engine Parts page.
