UG · PG / PGA · 2301 · 505 · EG
Genuine, OEM and reconditioned parts for Woodward marine engine governors — the UG, PG/PGA, 2301, 505 & EG actuator families — sourced beside Alang, shipped to India, UAE, Singapore & worldwide.
150 YEARS OF SPEED CONTROL
Amos Woodward patents a mechanical water-wheel governor in Rockford, Illinois — the foundation of a speed-control dynasty.
Woodward turns to engine speed control as diesel propulsion spreads, building the hydraulic governors that define the era.
The UG and PG mechanical-hydraulic governors arrive and go on to regulate countless marine main and auxiliary engines.
The 2301 and 505 electronic speed controls bring solid-state precision and actuator-based control to the engine room.
Digital 723 controls and EG/EGB actuators run modern diesels — while millions of legacy UG and PG units still need parts.
WHO IS WOODWARD
Woodward is the most widely fitted name in engine speed control. Founded in Rockford, Illinois in 1870, it built the hydraulic governors that regulated a century of marine diesels — the mechanical-hydraulic UG and PG, the pressure-compensated PGA, and later the electronic 2301 and 505 speed controls and EG actuators. A single engine room may run a 70-year-old UG-8 on the main engine and a modern 2301 control on the gensets. Wattmare supplies governor spare parts — and complete reconditioned governors — across every one of those generations.

GOVERNOR SERIES WE COVER
The classic mechanical-hydraulic governor — the UG-8 is the most recognised marine governor ever built. Ballheads, pilot valves, power pistons and drive shafts, genuine and reconditioned.
The pressure-compensated governor for larger main and auxiliary engines. We hold pilot valves, power cylinders, compensation needles and buffer springs for the full PG/PGA range.
Solid-state speed controls for diesel and turbine drives. We supply control cards, magnetic pickups and linkage hardware for the 2301 and 505 electronic platforms.

GLOSSARY
WHERE WE DELIVER
We ship Woodward governor parts from Alang / Bhavnagar to UAE, Dubai, Singapore, Greece, Turkey & worldwide in 24–48 hours.
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 parts for every Woodward marine governor, as well as complete reconditioned governors. Whether you run a mechanical-hydraulic UG-8, a pressure-compensated PGA-200, an electronic 2301 speed control or an EG actuator, we hold the internals you need and dispatch them worldwide in 24–48 hours.
Woodward began in Rockford, Illinois in 1870 with a mechanical water-wheel governor, then turned to engine speed control as diesel propulsion spread. In practice this means the parts market spans several families. The UG series (UG-8, UG-8L, UG-10, UG-25, UG-32, UG-40, UG-40L) is the classic mechanical-hydraulic governor. The PG and PGA series (PG, PGA, PGA-EG, PGA-58, PGA-200) added pressure compensation for larger engines. And the electronic 2301 and 505 controls, with EG and EGB actuators, brought solid-state precision. We supply spares across all of them.
Alongside the hydraulic governors, Woodward’s electronic and digital controls run modern engine rooms. The 2301 (2301A, 2301D) and 505 (505, 505E) speed controls sense engine speed with a magnetic pickup and command an actuator; the digital 723 carries this further. We also support the legacy SG, DYNA and TG governors on smaller and older diesels — the units distributors no longer stock parts for.
For class-critical or newbuild work, genuine Woodward parts are the safe choice. For routine planned maintenance, OEM-equivalent aftermarket parts cut cost by 30–50%. And for emergency repairs or budget overhauls — especially on obsolete UG, PG and SG governors — reconditioned parts and complete governors recovered from Alang, bench-tested and verified to specification, can save up to 70%. Every reconditioned unit ships with an inspection report, test results and a 30-day warranty.
Bhavnagar sits beside Alang, where hundreds of vessels are dismantled every year — including ships still running obsolete UG, PG, SG and TG governors. That gives Wattmare direct access to genuine, low-hour Woodward governors and internals that are simply unavailable from distributors, at a fraction of new-part cost and lead time. If you are searching for hard-to-find legacy Woodward parts, this is the fastest source in the world. Browse our reconditioned marine spare parts range, the wider governor spare parts category, or sister brand Regulateurs Europa.

FAQ
Yes — the UG-8 (UG-8 Dial, UG-8L) is our strongest Woodward line. We carry ballhead and flyweight assemblies, pilot valve plungers and bushings, power pistons, drive shafts, terminal shafts, speed-adjusting motors, dashpot needle valves and full gasket and seal kits. Many UG-8 governors are recovered low-hour beside Alang and reconditioned to specification.
We cover the mechanical-hydraulic UG range (UG-8, UG-8L, UG-10, UG-25, UG-32, UG-40, UG-40L), the PG and PGA pressure-compensated governors (PG, PGA, PGA-EG, PGA-58, PGA-200), the 2301 and 505 electronic speed controls (2301A, 2301D, 505, 505E), the EG actuator family (EGB, EG-3P, EG-6P, EPG) and specialty units (723 digital, SG, DYNA, TG-13).
Yes — legacy hydraulic governors are a core specialty. Older UG, PG, SG and TG governors are long out of production, so distributors no longer stock internals. Sitting beside Alang, we recover, inspect and recondition genuine Woodward parts that are otherwise impossible to find.
