THE KNOWLEDGE DESK
The main engine is the heart of every merchant vessel, and keeping it turning means having the right spare parts within reach — fast. Wattmare supplies genuine, OEM-equivalent and reconditioned spares for every major low-speed and medium-speed marine main engine, shipped worldwide from our base in Bhavnagar, beside the Alang ship-recycling yard. Whether you run a bulk carrier on MAN B&W power, a tanker on Wärtsilä, or an older vessel with a Sulzer or Pielstick engine, we source the wear parts, running gear and combustion components you need.
Most large merchant ships are driven by slow-speed two-stroke crosshead engines — MAN B&W MC and ME, Wärtsilä RT-flex, WinGD X, Mitsubishi UEC and Sulzer RTA/RND — coupled directly to the propeller. Smaller vessels and gensets use medium-speed four-stroke engines such as the Wärtsilä 32 and 46, Hanshin and Pielstick PA/PC. Their wear parts differ: two-strokes depend on cylinder liners, piston crowns, fuel valves and crosshead bearings, while four-strokes use cylinder heads, inlet and exhaust valves, pistons and main bearings. We carry spares for both.

Every part ships with documentation — material and test certificates for genuine parts, and inspection and measurement reports with photos for reconditioned parts.

For class-critical or newbuild work, genuine OEM parts are the safe choice. For routine planned maintenance, OEM-equivalent aftermarket parts cut cost by 30–50%. And for emergency repairs or budget overhauls, reconditioned parts recovered from Alang — inspected and certified to OEM tolerance — can save up to 70%. Use the comparison above to choose the right option for your vessel and your survey requirements.
Bhavnagar sits beside Alang, the world’s largest ship-recycling yard, where hundreds of vessels are dismantled every year. That gives Wattmare direct access to low-hour, genuine engine parts that are unavailable anywhere else — including spares for obsolete engines that manufacturers no longer produce. We recover, inspect, measure and certify each part before it ships, delivering OEM quality at a fraction of new-part cost and lead time. Browse a specific builder such as MAN B&W, Wärtsilä or Sulzer.
Send us your engine make and model with a photo or part number on WhatsApp, or use the quote form below. 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. We ship worldwide by air and sea with full export documentation.
Beyond individual spares, we supply complete overhaul kits matched to your maintenance schedule — decarbonising kits for routine top-end work, top-overhaul kits for cylinder-unit servicing, and major-overhaul kits for crankshaft and bearing renewal at class intervals. Each kit is assembled to your exact engine model with gaskets, seals, O-rings and fasteners included, so nothing is missing when the engine is opened up.

The fastest way to get the correct part is to send the engine nameplate, the maker’s drawing or part number, and a photo of the worn component. If you only have the engine model we can cross-reference the part from OEM parts catalogues. Our desk confirms the exact specification before anything ships, so you never receive a part that doesn’t fit.
