The MAN 12V16/24-GS-60Hz is a 12-cylinder, V-type, four-stroke medium-speed GenSet engine (bore 160 mm, stroke 240 mm). No rated output is stated here because the manufacturer documentation available to us does not give one for the V-type. This diesel engine operates on a 4-stroke principle, featuring a turbocharged in-line configuration, and is designed to meet stringent marine standards. The engine's bore and stroke dimensions measure 160 mm and 240 mm respectively, and it is configured in a V arrangement with 12 cylinders. The engine is compliant with IMO Tier II standards, making it suitable for auxiliary and genset applications. Over its operational life, common issues have included valve clearance adjustment failures leading to stress on valve bridge guides, connecting rod bolt preload inconsistencies, lube oil cooler overstress from improper tightening, coolant water quality deficiencies, and fuel injection valve opening pressure drops after new nozzle installations.

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.
