The complete guide
Wattmare is a specialist Mirrlees Blackstone 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 Mirrlees Blackstone-Mirrlees Blackstone four-stroke marine main engine, dispatched worldwide in 24–48 hours.
The four-stroke engines on this page are Mirrlees Blackstone — an English medium-speed engine builder (Mirrlees of Stockport, founded in the 1840s, and Blackstone of Stamford), now part of MAN Energy Solutions. The ESL series and K-Major power ships and power stations worldwide. We supply spares across all of them.
The single most important question on any Mirrlees Blackstone-Mirrlees Blackstone order is whether the engine is an ESL series, an ESL series or an ESL series. The Mirrlees Blackstone ESL series is camshaft-controlled — fuel pump, fuel cam, chain drive and mechanical exhaust-valve gear. The ESL series / K-Major and the Mirrlees Blackstone ESL 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 ESL series / K-Major / ESL series designation.
For every Mirrlees Blackstone ESL and K-Major 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 Mirrlees Blackstone ESL 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 ESL 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.
