A century of diesel
From Burmeister & Wain
to MAN Energy Solutions.
Burmeister & Wain founded
Founded in Copenhagen — the “B&W” half of the marque and one of the oldest names in marine engineering.
First diesel engine
B&W builds its first diesel under licence from Rudolf Diesel, beginning a low-speed two-stroke dynasty that still rules the seas.
MAN B&W is born
Germany’s MAN acquires Burmeister & Wain’s diesel business — the MC two-stroke goes on to dominate world shipping.
The electronic era
The camshaft-free ME, ME-C and ME-B arrive with electronic fuel injection and hydraulic exhaust valves — later joined by ME-GI dual-fuel.
MAN Energy Solutions
The OEM behind today’s MAN B&W two-stroke and four-stroke marine engines — and the parts we source for every generation.
Who is MAN B&W
The world’s most
fitted main engine.
MAN B&W is the most widely installed marine main-engine brand on earth — the great majority of large merchant ships are propelled by a MAN B&W two-stroke. The marque joins Germany’s MAN with Denmark’s Burmeister & Wain, merged in 1980 and today built by MAN Energy Solutions.
A single fleet can run the camshaft-controlled MC and MC-C, the electronic ME-C, ME-B and ME-GI, or the four-stroke L-series auxiliaries. Wattmare supplies spare parts across every one of those generations.
Engine series we cover
Every MAN B&W series,
two-stroke to four.
Mechanical 2-strokeMC / MC-C series
The camshaft-controlled two-stroke that powered a generation of merchant ships. Many are ageing out — exactly why fleets struggle to find parts. Our strongest Alang line.

The complete guide
MAN B&W engine spare parts, explained
Wattmare is a specialist MAN B&W 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 MAN B&W marine engine, dispatched worldwide in 24–48 hours.
The MAN B&W lineage
MAN B&W joins two of the oldest names in engineering: Germany’s MAN and Denmark’s Burmeister & Wain, building diesels from 1898 and merged in 1980, today built by MAN Energy Solutions. The mechanical MC and MC-C series (S50MC–S90MC, K90MC, K98MC and the L-types) powered a generation of merchant ships. The electronic ME-C, ME-B and ME-GI series replaced the camshaft with a hydraulic cylinder unit. We supply spares across all of them.
Two-stroke: MC versus ME-C
The single most important question on any MAN B&W order is whether the engine is an MC or an ME. The MC and MC-C are camshaft-controlled — fuel pump, fuel cam, chain drive and mechanical exhaust-valve gear. The ME-C, ME-B and ME-GI are electronically controlled, replacing all of that with a hydraulic cylinder unit (HCU), electronic fuel valves 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 MC or ME designation.
Four-stroke: the L-series
Alongside the two-strokes, MAN B&W’s medium-speed four-stroke engines power gensets and auxiliary sets. The L-series — L16/24, L21/31, L27/38, L28/32A, L32/40, L48/60CR and the dual-fuel L51/60DF, plus the V-versions — is among the most installed auxiliary engines afloat. We carry heads, pistons, liners, valves, fuel injection valves, fuel pumps and bearings for all of them.
The Alang advantage for legacy MC parts
Bhavnagar sits beside Alang, where hundreds of vessels are dismantled every year — including ships still running ageing MAN B&W MC and MC-C 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 MC 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 Wärtsilä and Sulzer.
How to order and what to expect
Send your MAN B&W engine make and model with a photo or part number on WhatsApp, or use the quote form. We confirm availability and price — usually within the hour — and dispatch in-stock items within 24 hours. Typical air-freight transit is 12–18 hours to the UAE, 16–24 to Singapore, 20–26 to Greece and Turkey, and 28–36 to Northern Europe.
FAQ
MAN B&W parts,
answered.
Do you supply MAN B&W S60MC cylinder liners?
Yes — cylinder liners are one of our strongest MAN B&W lines. We carry original-bore and reconditioned liners for the S60MC and S60MC-C, plus the rest of the S, L and K MC range (S50MC, S70MC, S80MC, S90MC, K90MC, K98MC), honed to OEM tolerance with measurement reports. Most legacy MC liners are recovered and reconditioned beside Alang.
What is the difference between MAN B&W MC and ME-C engine parts?
MC and MC-C engines are camshaft-controlled (mechanical) two-strokes — fuel pump, fuel cam and mechanical exhaust-valve actuation. ME-C, ME-B and ME-GI engines are electronically controlled, replacing the camshaft with a hydraulic cylinder unit (HCU), electronic fuel injection 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 MC or ME model.
Which MAN B&W engine models do you cover?
We cover the full two-stroke range — mechanical MC and MC-C (S35MC up to S90MC, L35MC–L90MC, K80MC–K98MC) and electronic ME-C, ME-B and ME-GI (S50ME-C, S60ME-C, S70ME-C, S80ME-C, G50ME–G95ME-C, plus S50/S60/S70ME-GI) — as well as the four-stroke L-series: L16/24, L21/31, L27/38, L28/32A, L32/40, L48/60CR, L51/60DF and the V-versions.
Are reconditioned MAN B&W parts class-approved?
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 MAN B&W parts carry full material and test certificates.
How fast can you deliver MAN B&W parts to Dubai?
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.
Can you supply MAN B&W fuel injection valves and fuel pumps?
Yes — fuel injection valves, injector nozzles, high-pressure fuel pumps, plungers and barrels for MC and MC-C engines, plus hydraulic cylinder units (HCU), fuel boosters and injection equipment for ME-C, ME-B and ME-GI engines, are stocked and bench-tested before dispatch.
What is the difference between genuine, OEM-equivalent and reconditioned parts?
Genuine parts come from the original maker (MAN Energy Solutions) 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.
Do you supply MAN B&W ME-GI and ME-B electronic engine parts?
Yes — ME-GI dual-fuel and ME-B electronic engines use a hydraulic cylinder unit (HCU), electronic fuel injection valves, exhaust-valve actuators and control-oil equipment in place of the camshaft. We source these running-gear and control parts along with the shared liners, covers, piston crowns and bearings.
Do you carry four-stroke L-series (L16/24, L27/38, L32/40) spares?
Yes — combustion and running-gear spares for the four-stroke L16/24, L21/31, L27/38, L28/32A, L32/40, L48/60CR and L51/60DF (and the V-versions), including cylinder heads, pistons, liners, inlet/exhaust valves, fuel equipment and bearings for gensets and auxiliary engines.
How do I get a price for a MAN B&W spare part?
Send your engine model and a photo or part number on WhatsApp (+91 96647 18068), or use the quote form. We confirm availability and price, usually within the hour — whether you need genuine, OEM-equivalent, used or reconditioned parts, or a complete overhaul kit.
Where do you ship MAN B&W parts and how are they packed?
We ship from Alang/Bhavnagar to the UAE, Dubai, Singapore, Greece, Turkey and every major port worldwide in 24–48 hours. Parts are export-packed with VCI wrapping, wooden crates and palletisation, with photos shared before dispatch and full export documentation included.
