Woodward Marine
Governor & Actuator Parts
Engine-room Woodward governor, actuator and digital control spare parts for diesel, dual-fuel and gas engines, and for turbines.
The Woodward equipment behind most engine-room enquiries
Woodward Inc. is a US manufacturer of governors, actuators and engine control systems, and its equipment has a long history in the engine room: mechanical-hydraulic UG governors on older diesel and steam-turbine drives, electronic actuators retrofitted onto that same hardware, and digital control systems on more recent propulsion and genset installations. Vessel Core supplies purchasing teams, superintendents, marine engineers, repair yards and maritime agents with spare parts across that full range, from classic governors still carried as ship spares through to digital engine and genset control on more recent tonnage.
UG-8, UG-10, UG-15 and UG-25 Universal Governors
Universal Governor units in isochronous or droop configuration, still catalogued individually as ship spares. They sit on older diesel drives and on steam-turbine drives, which is why the driven machine matters as much as the governor designation itself.
3161 Governor
The legacy 3161 governor, carried alongside the UG range in isochronous or droop configuration. Like the UG series it is still catalogued individually by marine parts brokers, so a nameplate photograph is often enough to begin identification.
EG-3P and EG-3PC proportional actuators
Proportional actuators driven from an electronic speed control. They are frequently the retrofit half of an installation whose governor body is decades older, so the actuator and the control it answers to are worth naming together.
EGB actuators and the UG-Actuator retrofit unit
EGB actuators, and the UG-Actuator retrofit unit with its own self-contained oil sump. Both appear as the driven element under a 2301A or 2301D control, and both are also requested as standalone spares.
PGA-EG and PGG-EG governor bodies
Hydro-mechanical governor bodies with electronic control and pneumatic backup tracking, rated for a range of marine engine sizes. The backup arrangement is part of the identity of the unit and should be stated on the enquiry.
2301A and 2301D Load Sharing and Speed Controls
Load Sharing and Speed Control systems, typically paired with an actuator such as an EGB or a UG-Actuator. The control and the actuator are separate items commercially, but they identify each other technically.
723 Plus Digital Control
Digital control for gas, diesel and dual-fuel reciprocating engines, used with its own compatible actuator. Control cards for these systems are requested separately from the control itself.
ProAct Digital and Digital Plus, and LECM modules
ProAct Digital and Digital Plus controllers for governing, sequencing and protection on large reciprocating engines in marine propulsion, and LECM engine control modules with validated gas, diesel and dual-fuel application software.
easYgen 2000, 3000 and 3200XT controllers
Paralleling and load-sharing controllers for genset switchboards. On these units the switchboard arrangement is part of the request, since the controller is identified by what it parallels as much as by its own type.
Woodward items that appear on RFQ lines
Supply coverage spans classic mechanical-hydraulic governors still carried as ship spares through to digital engine and genset control systems on more recent tonnage. Complete units, standalone actuators and the wear items around them are quoted as separate lines, so the ship can decide what to change now and what to carry as a running spare.

Genset control panel — general arrangement
A licensed photograph of Woodward equipment was not available at publication, so this technical reference illustrates the general arrangement shared by this equipment class.
Illustrative technical reference, not a photograph of Woodward equipment or a Vessel Core installed reference — a licensed photo was not available. Vessel Core has no dealership, distribution or partnership agreement with the manufacturer named; it operates as an independent spare parts supplier.
Turning a governor nameplate into a quotable line
Part numbers are helpful but not always available on older mechanical-hydraulic governors. A nameplate photo, the driven engine or turbine data and a photo of the linkage or actuator can be enough to begin technical cross-checking before supply routes are reviewed. The list below is what makes a Woodward enquiry answerable without a second round of questions.
- Governor or actuator type designation, in full
- Serial number from the governor or actuator nameplate
- Driven engine or turbine make and model
- Isochronous or droop mode, where relevant
- Part number, description and quantity
- OEM route, alternative route or both
- Nameplate photographed square-on
- Photographs of the linkage and mounting arrangement
- Photographs of the control cabinet and wiring
- Vessel name / IMO and company name
- Urgency level, port and ETA
- Excel list where several lines are requested
A governor is quoted against the engine it controls, not against a shelf code.
A Woodward item rarely stands on its own. The same actuator appears under different control systems, and the same control system drives more than one actuator, so the request has to describe an installed arrangement rather than a single code. What follows is how that fact - and the age spread from mechanical-hydraulic governors to digital control modules - changes the questions asked before any Woodward item is quoted.
A part number is welcome, not required
The request can include a complete part number, or it can start from the governor or actuator type designation, the serial number, the driven engine or turbine make and model, or photographs of the nameplate and mounting arrangement.
Control and actuator identified together
A 2301A or 2301D speed and load control is typically installed with an actuator such as an EGB or a UG-Actuator, and a 723 Plus digital control is used with its own compatible actuator. Naming both, or photographing the control cabinet and the actuator nameplate together, avoids a mismatched quotation.
Driven engine stated with the governor
The best Woodward RFQs connect the part to the driven engine. The engine or turbine make and model is asked for alongside the governor reference, because the same governor family is fitted to machines of very different size and duty.
Isochronous or droop confirmed
Where it is relevant, the operating mode is confirmed with the type designation. UG-8, UG-10, UG-15, UG-25 and 3161 units are catalogued in isochronous or droop configuration, so the mode belongs on the enquiry line rather than in a later clarification.
Evidence structured before routing
Governor or actuator nameplate, serial number, driven engine data, photographs, port and ETA are taken in as one intake. The request context is structured before supplier routing or quotation work begins.
OEM route or verified alternative
An OEM route or a verified alternative route can be reviewed where appropriate. The commercial request is then prepared for clearer supplier review and buyer reply, with urgency, port and ETA carried on the line.
Woodward RFQ enquiries - recurring questions
What information is needed to quote a Woodward governor or actuator?
Useful information includes the governor or actuator type designation (for example UG-8, UG-10, UG-15, UG-25, 3161, EG-3P, EGB, PGA-EG or PGG-EG), the serial number, the driven engine or turbine make and model, isochronous or droop mode where relevant, and photographs of the nameplate and mounting arrangement. Vessel/IMO, urgency, port and ETA help route the request.
Can a Woodward governor be identified from photographs alone?
Often yes. Clear photographs of the nameplate, the model and serial number, the linkage or actuator arm, and the mating engine or turbine data are usually enough to begin identification, particularly for the mechanical-hydraulic UG series and the 3161 governor, which are still catalogued individually by marine parts brokers.
Do 2301 or 723 Plus digital controls need to be quoted together with an actuator?
Not necessarily, but the pairing matters for identification. A 2301A or 2301D speed and load control is typically installed with an actuator such as an EGB or a UG-Actuator, and a 723 Plus digital control is used with its own compatible actuator. Stating both the control model and the actuator model, or sending photographs of the control cabinet and the actuator nameplate together, avoids a mismatched quotation.
Is Vessel Core an authorised Woodward dealer?
No. Vessel Core is independent of Woodward Inc. Woodward names and model designations are used on this page only to help identify equipment already installed on board, so that a spare-parts request can be structured and routed for quotation; naming this equipment implies no dealer, distributor or partner relationship, and no endorsement by the manufacturer.
