Genuine, OEM and reconditioned spares for Mitsubishi two-stroke main engines — the Mitsubishi UEC, the common-rail UEC-LS / UEC-Eco and the Mitsubishi UEC series — sourced beside Alang, shipped to India, UAE, Singapore & worldwide.
A century of diesel
Mitsubishi Heavy Industries traces to the 1884 Nagasaki shipyard — Japan’s marine-engineering powerhouse.
Mitsubishi develops its own UE low-speed two-stroke marine diesel — a fully in-house Japanese design.
The fuel-efficient UEC long-stroke family arrives — two-stroke mains for bulk carriers, tankers and container ships.
Mitsubishi adds electronically-controlled UEC-LSE engines — common-rail injection and lower emissions.
Mitsubishi UEC engines power fleets worldwide — Wattmare keeps every generation running with genuine, OEM-equivalent and Alang-reconditioned spares.
Who is Mitsubishi
Mitsubishi Heavy Industries (MHI) of Japan designs and builds the UE / UEC low-speed two-stroke marine main engines entirely in-house — a Japanese engineering line that has powered merchant ships since the 1950s and continues today as the fuel-efficient UEC-LSE series.
A single fleet can run the long-stroke UEC-LS series, the electronically-controlled UEC-LSE / Eco engines, or the legacy UEC-LA mains — and Wattmare supplies genuine, OEM-equivalent and Alang-reconditioned spares across every Mitsubishi UEC bore.
Engine series we cover
Mechanical 2-strokeThe 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.
View all 23 UEC models
Common-rail 2-strokeThe camshaft-free common-rail two-stroke — fuel injection and exhaust valves controlled electronically from a high-pressure rail. We hold rail valves, flow-control units, injection equipment, liners and crowns.
View all 3 UEC models
Current 2-strokeThe current long-stroke UEC-LS and electronic UEC-Eco generation — UEC33LS up to UEC85LSE. Liners, piston crowns, common-rail injection and exhaust-valve parts.

The complete guide
Wattmare is a specialist Mitsubishi 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 Mitsubishi two-stroke marine main engine, dispatched worldwide in 24–48 hours.
The UE / UEC two-stroke engines on this page are designed and built in-house by Mitsubishi Heavy Industries (MHI) of Japan — one of the country’s oldest and largest engineering groups, tracing back to the 1884 Nagasaki shipyard. MHI introduced its own UE low-speed marine diesel in the 1950s and grew it into the fuel-efficient UEC long-stroke family. The camshaft-controlled UEC-LA and UEC-LS series (UEC33 through UEC85) powered a generation of merchant ships, and the electronically-controlled UEC-LSE / Eco engines carry the line forward today. We supply spares across all of them.
The single most important question on any Mitsubishi order is whether the engine is a camshaft-controlled UEC-LS / LA or an electronically-controlled UEC-LSE / Eco. The camshaft UEC drives its fuel pumps from a chain-driven cam; the Eco engines replace that with a common-rail supply unit, rail valves and hydraulic exhaust-valve actuation. Liners, piston crowns and bearings are common by bore, but injection and actuation parts are entirely different — always give us your exact UEC-LS or UEC-LSE designation.
For every UEC bore we stock cylinder liners, cylinder covers, piston crowns and skirts, piston rings, connecting-rod and main bearings, fuel injection valves, fuel pumps and plungers, exhaust-valve spindles and seats, chain drives, camshaft segments and turbocharger spares — genuine, OEM-equivalent and Alang-reconditioned, for both camshaft UEC-LS / LA and electronic UEC-Eco engines.
Bhavnagar sits beside Alang, where hundreds of vessels are dismantled every year — including ships still running ageing Mitsubishi UEC two-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 UEC 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.
Send your Mitsubishi 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
Yes — cylinder liners are one of our strongest Mitsubishi lines. We carry original-bore and reconditioned liners for the UEC and UEC, plus the rest of the UEC range (UEC33-UEC85), honed to OEM tolerance with measurement reports. Most legacy UEC liners are recovered and reconditioned beside Alang.
The Mitsubishi UEC is a camshaft-controlled (mechanical) two-stroke — fuel pump, fuel cam and mechanical exhaust-valve actuation. The UEC-LS / UEC-Eco and the Mitsubishi UEC 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 UEC-LS or UEC-LSE model.
We cover the full UEC two-stroke range — the long-stroke UEC-LS series (UEC33LS, UEC37LS, UEC45LS, UEC50LS, UEC52LS, UEC60LS, UEC68LS, UEC75LS, UEC85LS), the electronically-controlled UEC-LSE / Eco engines, and the legacy UEC-LA series — every UEC bore from UEC33 to UEC85.
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 Mitsubishi 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 Mitsubishi UEC engines, plus common-rail supply units, rail valves, flow-control units (FCU) and injection equipment for UEC-LS / UEC-Eco and UEC series engines, are stocked and bench-tested before dispatch.
Genuine parts come from the original maker (Mitsubishi / Mitsubishi) 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 Mitsubishi UEC parts are our specialty. Beside Alang we recover low-hour fuel pumps, chain drives, liners, crowns and running gear from UEC-powered vessels being dismantled, then inspect and certify them. For legacy UEC-LA and camshaft UEC-LS engines this is often the fastest source in the world.
Yes — we supply UEC turbocharger spares (including Mitsubishi MET turbocharger parts), chain drives, fuel pumps, camshaft segments, bearings and complete running gear for the UEC-LA, UEC-LS and UEC-Eco series, genuine and Alang-reconditioned.
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.
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.
Yes — decarbonising, top-overhaul and major-overhaul kits assembled to your exact the UEC33-UEC85 range / UEC or UEC series model, with liners, piston rings, fuel injection valves, exhaust-valve spindles, stuffing-box rings, gaskets, O-rings and fasteners included.
