Crew, engineers, and operators on board vessels rely on powerful, reliable engines to keep their operations running smoothly. Wärtsilä's 6LW32, a product of their renowned W32 family, delivers precisely that. This robust diesel engine boasts a 3120 kW power output, fueled by HFO/MGO. Its 6-cylinder, L-configured design features a 320 mm bore, 400 mm stroke, and a 750 RPM speed. The Wärtsilä 6LW32 utilizes Common Rail Medium-Speed technology, incorporating turbocharging and intercooling for enhanced performance. It's designed for reliable operation, with a seawater and freshwater cooling system and charge air cooling via a cooler. The engine complies with IMO Tier II (MARPOL 73/78 Annex VI) standards. The Wärtsilä 6LW32 is a proven workhorse, continuously updated since its introduction in the 1980s, with over 2500 units sold.

For marine equipment hardly any maker or authorised dealer will name a price while the vessel is unknown. With the vessel details, availability and price can be settled faster; without them we may have to ask first, which costs a few days. If you are not allowed to name the vessel, a photo of the rating plate is enough — attach it below or send it as a reply to our confirmation e-mail.
