This 12-cylinder, 4-stroke V-type marine diesel engine operates on a high-efficiency turbocharged design, featuring direct injection and robust construction, making it suitable for both propulsion and generator set applications. The MaK 12VM34-GS-60Hz, part of the M34-GS family, delivers a power output of 6120 kW at 900 rpm, running on heavy fuel oil (HFO) or marine diesel oil (MDO). This engine, introduced in 1994, is designed to comply with IMO Tier II emissions standards and has been in continuous production under Caterpillar Marine Power Systems. With over 1600 units installed since its launch, the 12VM34-GS-60Hz is known for its durability and reliability in marine propulsion and power generation systems. Key maintenance considerations include monitoring the specific fuel oil consumption (SFOC) and boost pressure, managing fuel quality, and ensuring the integrity of the turbocharger and cooling systems to prevent corrosion.

Free of charge — we forward your request to qualified suppliers for MaK (Caterpillar) equipment from our network of over 114,000 maritime companies.

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we usually come back with prices; without them we have to ask first, which costs a few days. If you cannot share the vessel, a photo of the equipment’s rating plate does the same job — send it as a reply to our confirmation e-mail.
