Marine vessels often require powerful and versatile engines capable of handling demanding operating conditions. The Wärtsilä 6LW25 engine is a medium-speed trunk piston engine designed for this purpose. It features six cylinders arranged in a linear configuration, with a bore of 250 millimeters and a stroke of 350 millimeters. The engine operates at a rotational speed of 1000 revolutions per minute and can utilize both heavy fuel oil (HFO) and marine gas oil (MGO) as fuel. It boasts a power output of 1650 kilowatts. The Wärtsilä 6LW25 is known for its reliability and fuel efficiency, with a time between overhaul (TBO) of up to 32,000 hours. The engine is compliant with IMO Tier III emissions standards, achieved through its incorporation of a NOx Reducer (NOR) system. This system utilizes a selective catalytic reduction (SCR) process to minimize nitrogen oxide emissions.

Free of charge — send us your request for Wärtsilä equipment. Our team checks it and replies by e-mail.

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we can check availability and prices faster; without them we may have to ask first, which can cost a few days. If you cannot share the vessel, a photo of the equipment’s rating plate does the same job — attach it below or send it as a reply to our confirmation e-mail.
