A century of diesel
Yanmar is founded in Osaka, Japan.
Yanmar builds the world’s first practical small diesel engine.
The medium-speed N and EY four-stroke marine engines power gensets and propulsion worldwide.
Yanmar refines its marine engines for low emissions and high efficiency.
Wattmare keeps every Yanmar N, EY and HAL engine running with genuine, OEM-equivalent and Alang-reconditioned spares.
Who is Yanmar
Yanmar, of Japan, builds the N-series and EY-series medium-speed four-stroke marine engines, plus the HAL and KFL ranges. Yanmar engines power ship gensets, auxiliaries and propulsion across the world fleet.
A single fleet can run the N-series (6N18, 6N21, 6N330), the EY-series (6EY18, 6EY22, 6EY26), or the legacy HAL / KFL engines — and Wattmare supplies genuine, OEM-equivalent and Alang-reconditioned spares across every Yanmar bore.

Diagnose the fault
| Symptom | Likely Yanmar-Yanmar parts to inspect |
|---|---|
| Loss of compression or power on one unit | Cylinder liner, piston rings, piston crown |
| High exhaust temperature on one cylinder | Fuel injection valve / nozzle, exhaust valve spindle |
| Knocking or pounding from the crankcase | Main, crankpin or crosshead bearings |
| Excessive cylinder-oil consumption | Liner wear, piston rings, stuffing-box rings |
| Difficult or failed starting | Starting air valve, fuel pump (plunger / barrel) or rail valve |
| Black or smoky exhaust | Fuel valve nozzles, slide valves, turbocharger interface |
| Oil leak at the piston-rod gland | Stuffing box scraper and sealing ring set |
| Water in the combustion space | Cylinder cover, cooling-jacket O-rings, liner |

The complete guide
Wattmare is a specialist Yanmar 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 Yanmar-Yanmar four-stroke marine main engine, dispatched worldwide in 24–48 hours.
The four-stroke engines on this page are built by Yanmar of Japan, a diesel-engine pioneer since 1912 and maker of the world’s first practical small diesel in 1933. The N, EY and HAL series power ship gensets, auxiliaries and propulsion worldwide. We supply spares across all of them.
The single most important question on any Yanmar-Yanmar order is whether the engine is an N-series, an N-series or an EY-series. The Yanmar N-series is camshaft-controlled — fuel pump, fuel cam, chain drive and mechanical exhaust-valve gear. The N-series / EY-series and the Yanmar EY-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 N-series / EY-series / EY-series designation.
For every Yanmar N, EY and HAL bore we stock cylinder liners, cylinder heads, piston crowns and skirts, piston rings, connecting-rod and main bearings, fuel injectors, fuel pumps, inlet and exhaust valves, camshaft parts and turbocharger spares — genuine, OEM-equivalent and Alang-reconditioned.
Bhavnagar sits beside Alang, where hundreds of vessels are dismantled every year — including ships still running ageing Yanmar N-series 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 N-series 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 Yanmar 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 Yanmar-Yanmar lines. We carry original-bore and reconditioned liners for the N-series and N-series, plus the rest of the N-series range (6N18 to 6EY26), honed to OEM tolerance with measurement reports. Most legacy N-series liners are recovered and reconditioned beside Alang.
The Yanmar N-series is a camshaft-controlled (mechanical) four-stroke — fuel pump, fuel cam and mechanical exhaust-valve actuation. The N-series / EY-series and the Yanmar EY-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 N and EY range or EY-series model.
We cover the full Yanmar range — the N-series (6N18, 6N21, 6N330), the EY-series (6EY18, 6EY22, 6EY26), and the legacy HAL / KFL engines — every Yanmar bore.
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 Yanmar 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 Yanmar N-series engines, plus common-rail supply units, rail valves, flow-control units (FCU) and injection equipment for N-series / EY-series and EY-series engines, are stocked and bench-tested before dispatch.
Genuine parts come from the original maker (Yanmar / Yanmar) 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 Yanmar N-series parts are our specialty. Beside Alang we recover low-hour fuel pumps, chain drives, liners, crowns and running gear from N-series-powered vessels being dismantled, then inspect and certify them. For the N and EY range and N-series engines this is often the fastest source in the world.
Yes — turbocharger spares, fuel injectors, pumps, camshaft parts, bearings and complete running gear for the Yanmar N, EY and HAL series, genuine and Alang-reconditioned.
