Genuine, OEM-equivalent and Alang-reconditioned governor parts for mechanical-hydraulic and electronic speed control systems — dispatched worldwide in 24-48 hours from Bhavnagar, India.

A failed engine governor is one of the few faults that can put a vessel on standby in minutes — speed hunts, the engine trips on overspeed, or load-sharing collapses across a paralleled plant. Wattmare supplies governor spare parts for the speed-control systems that sit on virtually every marine main and auxiliary engine afloat, covering mechanical-hydraulic, electro-hydraulic and fully electronic governors. We stock and source parts for Woodward, Regulateurs Europa, Heinzmann, Governors America and Yanmar units, in genuine, OEM-equivalent and reconditioned grades.
Operating from Bhavnagar beside the Alang ship-recycling yard gives us direct access to governors removed from decommissioned vessels — drive shafts, ballhead assemblies, pilot valves and actuators that are stripped, inspected and bench-tested before resale. That same network feeds our main engine and auxiliary engine programmes. Whether you need a complete reconditioned governor or a single seal kit, we ship to UAE, Singapore and Europe within 24-48 hours.
ANATOMY OF A MARINE GOVERNOR

GOVERNOR BRANDS WE SUPPLY

Mechanical-hydraulic & electronic
The dominant name in marine governing — from the legendary UG and PGA mechanical-hydraulic units to the 721/723 and ProAct electronic actuators. We carry ballhead and drive assemblies, pilot valve plungers, buffer springs, terminal shaft seals and full overhaul kits for the UG-8, UG-40, PGA and PGG ranges.

Viking & Lysander control
Widely fitted on European-built medium and slow-speed engines. We supply spares for the Viking mechanical-hydraulic and Lysander electronic governor families — pilot valve bushes, power piston assemblies, speed-setting motors, drive couplings and gasket sets for common workshop overhauls.
Electronic speed governing & actuators
German electronic governing specialist used across generator sets and propulsion plant. We source proportional and integral actuators, pickups, control units and linkage hardware for the StG and E-series, plus the magnetic speed sensors and connectors that fail most often in service.
GAC electronic controls & actuators
GAC electronic governing kit is found on countless auxiliary and emergency gensets. We supply speed-control units, ESD and ADC actuators, magnetic pickups and wiring harnesses for the ESC and ACB ranges — typically the fastest electronic governor parts to dispatch.
Built-in mechanical governors
Yanmar marine auxiliary and propulsion engines run integral mechanical and electronic governors. We carry governor weights, springs, link rods, actuators and seal kits for the EY, NSA, NHL and 6N series, in genuine and OEM-equivalent grades alongside reconditioned units pulled at Alang.

THE KNOWLEDGE DESK
The governor holds engine speed at the set point regardless of load. On a single propulsion engine it manages acceleration, overspeed protection and steady-state running; on a paralleled generator plant it also sets droop or isochronous load sharing so that machines share kW correctly. A small fault here shows up as hunting, surging, overspeed trips or one alternator hogging the load — symptoms that send crews looking at the governor long before the engine itself is at fault.

Mechanical-hydraulic governors such as the Woodward UG and PGA, and the Regulateurs Europa Viking, use a rotating ballhead, pilot valve and hydraulic power piston. They are robust and field-serviceable, which is why so many are still in service and why Alang is a rich source of reconditionable cores. Electronic governors — Woodward 2301A/ProAct, Heinzmann StG, Governors America ESD/ESC — split the speed sensing, control logic and actuator into separate parts, each of which can be replaced individually.
For class-critical propulsion control many superintendents specify genuine parts. For ancillary gensets and non-class items, OEM-equivalent components offer the same fit and function at lower cost. Where a complete unit is needed quickly, an Alang-sourced reconditioned governor — fully stripped, re-sealed and bench-tested — is often the fastest route back to sea.

Bhavnagar sits beside the world's largest ship-recycling yard. Governors, actuators and pickups removed from decommissioned vessels pass through our workshop daily, giving us cores for obsolete and hard-to-find models that OEMs no longer stock. This is the same sourcing engine behind our turbocharger and auxiliary engine programmes.
Governor part numbers are unforgiving — a Woodward UG-8 spring or a GAC actuator must match the exact variant. Always quote the full nameplate and serial. Our team cross-references against OEM data so the kit that arrives fits, and we confirm hydraulic governor oil grade and pickup gap on request before dispatch.

FAQ
We supply spare parts for Woodward, Regulateurs Europa, Heinzmann, Governors America (GAC) and Yanmar marine governors, covering mechanical-hydraulic, electro-hydraulic and electronic types. We also source other makes on request through our Alang network.
Yes. For most lines we can quote three grades — genuine OEM, OEM-equivalent, and Alang-reconditioned — so you can match budget, lead time and pedigree to each item. Class-critical propulsion control is typically supplied genuine.
Reconditioned governors and assemblies are removed from decommissioned vessels at Alang, fully dismantled, measured against wear limits, reassembled with new seals and springs, and bench-tested for speed response before resale. Worn cores are rejected.
Confirmed orders for stocked items ship the same or next working day, with delivery to UAE, Singapore and Europe typically within 24-48 hours by air freight. Sourced items are quoted with a confirmed lead time.
Yes. Where a full unit is needed quickly we supply complete reconditioned governors and actuators, bench-tested and re-sealed, as well as new genuine units where available from the OEM.
Send the governor nameplate — model, serial number and the engine it serves — plus a photo of the part if possible. We cross-reference against OEM data to confirm the correct spare before quoting.
Yes. We carry ballhead and drive assemblies, pilot valve sets, buffer springs, terminal shaft seals and overhaul kits for the UG-8, UG-40, PGA and PGG mechanical-hydraulic governors, plus electronic 2301A and ProAct parts.
Yes. We source Heinzmann StG and E-series actuators and pickups, and Governors America ESD, ESC, ACB and ADC speed controls and actuators, in new and reconditioned grades.
Hunting often originates in the governor (fatigued springs, worn pilot valve, wrong droop) but can also stem from fuel system or injection faults. We can advise on the most likely governor parts, but confirm the diagnosis with your engine maker's procedure.
Often, yes. Because we draw cores from ships being recycled at Alang, we can frequently supply assemblies and parts for older governors that OEMs no longer stock. Send us the nameplate and we will check availability.
We export worldwide, with established air-freight routes to the UAE, Singapore, Europe and other major bunkering and repair ports. We prepare documentation to match your vessel and port-of-delivery requirements.
Yes. Every reconditioned governor is bench-tested for speed response and leak-checked after re-sealing. We can share the test record on request before dispatch.
On request we confirm the recommended hydraulic governor oil grade for mechanical-hydraulic units and the correct magnetic pickup air gap for electronic systems before the parts are dispatched.
