Pielstick · SEMT · PC · PA · Four-stroke
Genuine, OEM and reconditioned spares for Pielstick four-stroke main engines — the Pielstick PC, the common-rail PC / PA and the MAN PC series — sourced beside Alang, shipped to India, UAE, Singapore & worldwide.
A century of diesel
The engineer Gustav Pielstick gives his name to a line of high-output medium-speed marine diesels.
France’s SEMT (Société d’Études de Machines Thermiques) builds the Pielstick PC and PA four-stroke engines.
The PC medium-speed four-stroke powers naval ships, ferries, tugs and gensets worldwide, licence-built across the globe.
The compact, high-output PA6 becomes a naval, patrol-craft and genset standard.
SEMT Pielstick passed to MAN in 2006; Wattmare keeps every PC and PA generation running with genuine, OEM-equivalent and Alang-reconditioned spares.
Who is Pielstick
Pielstick — SEMT Pielstick of France — designs the PC and PA medium-speed four-stroke marine diesel engines, named after the engineer Gustav Pielstick. Licence-built worldwide and now part of the MAN group, Pielstick engines have powered naval ships, ferries, tugs, offshore vessels and gensets since the 1950s.
A single fleet can run the heavy-duty PC series (PC2-5, PC2-6, PC4-2), the compact high-output PA series (PA5, PA6, PA6B, PA6-STC), or older PC2 / PA4 mains — and Wattmare supplies genuine, OEM-equivalent and Alang-reconditioned spares across every Pielstick bore.

Engine series we cover

The complete guide
Wattmare is a specialist Pielstick engine 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 Pielstick four-stroke marine main engine, dispatched worldwide in 24–48 hours.
The four-stroke engines on this page are the SEMT Pielstick PC and PA designs of France — one of the oldest names in engineering. Pielstick of France acquired the Pielstick diesel business in 1997, and in 2015 the line passed to MAN, the MAN group. The mechanical Pielstick PC series (PC2–PA6, including the PA6B high-output variants) powered a generation of merchant ships. The common-rail PC / PA replaced the camshaft with an electronically controlled high-pressure rail, and the current PC series (PC2–PA6) carries it forward. We supply spares across all of them.
The single most important question on any Pielstick order is whether the engine is an PC, an PC or an PC series. The Pielstick PC is camshaft-controlled — fuel pump, fuel cam, chain drive and mechanical exhaust-valve gear. The PC / PA and the MAN PC series are electronically controlled, replacing the camshaft with a common-rail supply unit, rail valves, flow-control units (FCU) and hydraulically actuated exhaust valves. Liners, covers, crowns and bearings are broadly common by bore, but injection and actuation parts are entirely different — always give us your exact PC / PA designation.
Alongside the four-strokes, Pielstick’s medium-speed four-stroke engines power gensets and auxiliary sets. The range — Pielstick PA5, PA6, PA6B, PC2 and PC4, plus the V-versions — is among the most installed auxiliary engines afloat. While this page focuses on the four-stroke mains, we also carry heads, pistons, liners, valves, fuel injection valves, fuel pumps and bearings for these four-strokes.
Bhavnagar sits beside Alang, where hundreds of vessels are dismantled every year — including ships still running ageing Pielstick PC four-stroke 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 PC fuel pumps, chain drives, liners or running gear, 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 — cylinder liners are one of our strongest Pielstick lines. We carry original-bore and reconditioned liners for the PC and PC, plus the rest of the PC range (PC2 to PA6), honed to OEM tolerance with measurement reports. Most legacy PC liners are recovered and reconditioned beside Alang.
The Pielstick PC is a camshaft-controlled (mechanical) four-stroke — fuel pump, fuel cam and mechanical exhaust-valve actuation. The PC / PA and the MAN PC series are electronically controlled, replacing the camshaft with a common-rail supply unit, rail valves, flow-control units (FCU) and hydraulically actuated exhaust valves. Liners, crowns and bearings are broadly similar by bore, but the injection and exhaust-valve actuation parts are completely different — always quote your exact the PC and PA range or PC series model.
We cover the full four-stroke range — the current MAN PC series (PC2 to PA6), the common-rail PC / PA (PC2 to PA6) and the legacy Pielstick PC (PC2 up to PA6, including the STC and B variants) — 33 models in all. We also supply the four-stroke medium-speed Pielstick PA5, PA6, PA6B, PC2 and PC4.
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 Pielstick 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 — fuel injection valves, injector nozzles, high-pressure fuel pumps, plungers and barrels for Pielstick PC engines, plus common-rail supply units, rail valves, flow-control units (FCU) and injection equipment for PC / PA and PC series engines, are stocked and bench-tested before dispatch.
Genuine parts come from the original maker (Pielstick / MAN) 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 Pielstick PC parts are our specialty. Beside Alang we recover low-hour fuel pumps, chain drives, liners, crowns and running gear from PC-powered vessels being dismantled, then inspect and certify them. For the PC and PA range and PC engines this is often the fastest source in the world.
Yes — combustion and running-gear spares for the four-stroke medium-speed Pielstick PA5, PA6, PA6B, PC2 and PC4 (and the V-versions), including cylinder heads, pistons, liners, inlet/exhaust valves, fuel equipment and bearings for gensets and auxiliary engines.
