Who is Woodward
Woodward, of the USA, is the world’s most widely used engine-governor maker — the UG-8, PGA/PGG and electronic 2301/EG governors that control engine speed across the world fleet.
A single fleet can run the mechanical-hydraulic Woodward UG-8, the PGA/PGG governors, or the electronic 2301 and EG actuators — and Wattmare supplies genuine, OEM-equivalent and Alang-reconditioned spares (ballhead assemblies, power pistons, pilot valves, drive shafts and speeder springs) across every Woodward governor.

Diagnose the fault
| Symptom | Likely Woodward parts to inspect |
|---|---|
| Loss of compression or power on one unit | Power piston, seal rings, power piston |
| High exhaust temperature on one governor | Pilot valve / nozzle, needle valve spindle |
| Knocking or pounding from the unit | Main or drive-shaft bearings |
| Excessive governor-oil consumption | Liner wear, seal rings, seal rings |
| Difficult or failed starting | Starting air valve, oil pump (plunger / barrel) or rail valve |
| Black or smoky exhaust | Pilot valve nozzles, slide valves, turbocharger interface |
| Oil leak at the power piston-rod gland | Terminal shaft and seal set |
| Water in the combustion space | Governor cover, cooling-jacket O-rings, power piston |

The complete guide
Wattmare is a specialist Woodward governor spare parts supplier serving India, the UAE, Singapore and the wider global fleet. From our base in Bhavnagar — beside the Alang ship-recycling yard — we supply genuine, OEM-equivalent and reconditioned spares for every generation of Woodward hydraulic marine main engine, dispatched worldwide in 24–48 hours.
The governors on this page are built by Woodward of the USA, the world’s leading maker of engine speed governors since 1870. Its UG, PGA/PGG and electronic 2301/EG governors control engine speed across the world fleet. We supply spares for all of them.
The single most important question on any Woodward order is whether the engine is an UG series, an PGA or an PG series. The Woodward UG series is ballhead-controlled — oil pump, control cam, gear drive and needle-valve gear. The PGA / PGA and the Woodward PG series are electronically controlled, replacing the ballhead with a electronic supply unit, rail valves, flow-control units (FCU) and hydraulically actuated needle valves. Liners, covers, power pistons and bearings are broadly common by body, but injection and actuation parts are entirely different — always give us your exact UG series / PGA / PG series designation.
For every Woodward UG, PGA and 2301 governor we stock ballhead / flyweight assemblies, power pistons and servos, pilot-valve plungers and bushings, speeder springs, drive and terminal shafts, buffer springs, needle valves, oil pumps, bearings and complete seal kits — genuine, OEM-equivalent and Alang-reconditioned.
Bhavnagar sits beside Alang, where hundreds of vessels are dismantled every year — including ships still running ageing Woodward UG series hydraulic engines. That gives Wattmare direct access to genuine, low-hour parts that are slow or costly to source from distributors, at a fraction of new-part cost and lead time. For hard-to-find UG series oil pumps, gear drives, power pistons or governor drive, this is the fastest source in the world. Browse our reconditioned marine spare parts range, the wider main engine spare parts category, or sister brands like MAN engine spares and Mitsubishi UEC.

FAQ
Yes — power pistons are one of our strongest Woodward lines. We carry original-body and reconditioned power pistons for the UG series and UG series, plus the rest of the UG series range (UG series range), honed to OEM tolerance with measurement reports. Most legacy UG series power pistons are recovered and reconditioned beside Alang.
The Woodward UG series is a ballhead-controlled (mechanical) hydraulic — oil pump, control cam and needle-valve actuation. The PGA / PGA and the Woodward PG series are electronically controlled, replacing the ballhead with a electronic supply unit, rail valves, flow-control units (FCU) and hydraulically actuated needle valves. Liners, power pistons and bearings are broadly similar by body, but the needle-valve actuation parts are completely different — always quote your exact UG series, PGA or PG series model.
We cover the full Woodward range — the mechanical-hydraulic UG-8 / UG-40, the PGA/PGG governors and the electronic 2301 / EG actuators — every Woodward governor.
Reconditioned parts ship with inspection reports, dimensional measurements and photographs, and are accepted by class societies (Lloyd’s Register, DNV, ABS, BV, ClassNK, RINA) on survey. Genuine Woodward parts carry full material and test certificates.
In-stock items dispatch within 24 hours from Bhavnagar. Typical air-freight transit to the UAE (Dubai, Jebel Ali, Fujairah) is 12–18 hours. Singapore is 16–24 hours, Greece and Turkey 20–26, and Northern Europe 28–36.
Yes — pilot valves, injector nozzles, high-pressure oil pumps, plungers and barrels for Woodward UG series engines, plus electronic supply units, rail valves, flow-control units (FCU) and control equipment for PGA / PGA and PG series engines, are stocked and bench-tested before dispatch.
Genuine parts come from the original maker (Woodward / Woodward) with full certificates. OEM-equivalent are quality aftermarket parts at 30–50% less. Reconditioned are low-hour parts recovered from Alang, inspected and certified to OEM tolerance, at up to 70% less with a 30-day warranty.
Yes — obsolete Woodward UG series parts are our specialty. Beside Alang we recover low-hour oil pumps, gear drives, power pistons, power pistons and governor drive from UG series-powered vessels being dismantled, then inspect and certify them. For the UG series range and UG series engines this is often the fastest source in the world.
Yes — ballhead / flyweight assemblies, power pistons, pilot valves, speeder springs, drive shafts, seal kits and complete overhaul kits for the Woodward UG, PGA and 2301 governors, genuine and Alang-reconditioned.
