The Yanmar Z280 was launched during the 1980s as the successor to the massively successful ZL engine. The Z280 engine retained the 280 mm cylinder bore of the ZL engine and was still one of Yanmar’s larger medium-speed diesel engines up until that point, with all other Yanmar medium-speed engines being within the 300 mm cylinder bore. The Z280 engine was developed primarily as a robust propulsion engine for small sized vessels such as fishing vessels, workboats, tugs and small cargo vessels. Auxiliary engine applications were introduced later on for larger vessels. With a cylinder bore size of 280 mm, the Z280 engine produced power of about 1,600 PS to 2,000 PS, with a crankshaft speed in the range of 650 rpm to 720 rpm. Some features of the Z280 engine were: cast iron engine block with high rigidity; special wear-resistant cast iron cylinder liners, which would have upgraded versions down the line (2-valve pocket and 4 valve-pocket type); 4-valve type cylinder head with high cooling efficiency between exhaust valves; carbon steel RR forged crankshaft giving 15% more strength to crankpins and main journals. 

The Z280 engine went on to become one of Yanmar’s most popular medium-speed diesel engines, with many Z280 engines still active on vessels decades years after their introduction in the market. But because the Z280 engines are legacy engines now, their production has long been discontinued by Yanmar. But that is where Alang Maritime can help out, especially when it comes to major engine components. As an independent Yanmar specialist, we maintain stock of Yanmar Z280 original parts that we have accumulated over decades and we have access to unused surplus engine parts of Z280 from decommissioned vessels.
