The Yanmar ZL engine is a heavy-duty diesel engine that was launched by Yanmar 1978, specifically 6ZL-UT. It was a revolutionary engine at the time for being the world’s first medium-speed 4 cycle marine auxiliary engine capable of using C heavy oil with a viscosity rate of 1,500 seconds. The engine had applications as a propulsion engine on smaller vessels and as auxiliary engines on medium sized vessels such as fishing vessels and cargo ships. The ZL engine had a solid build and a rigid framework. Boasting a cylinder bore of 280 mm, the ZL engine delivered power of about 1,400 Ps at an operating speed of about 720 rpm. The ZL engine was built to handle harsh maritime environments with a solid bedplate, durable cylinder block, and in-site replacement capabilities for pistons. Being an engine of the 1970s, the ZL engine mainly used a full mechanical engine management system. The ZL engine was instrumental to Yanmar’s medium-speed diesel engine success as it was the first 280 mm cylinder bore that Yanmar had launched. 

Because the ZL engines are very much legacy engines now, their production has long been discontinued by Yanmar and even their licensees, and that is a big problem for the few vessels that still sail with these engines. But that is where Alang Maritime can help out. Alang Maritime is your best bet for quality Yanmar ZL engine parts, especially the major ones.
