(1979 / Marine Product)
This was the first marine diesel engine manufactured exclusively by Yamaha Motor. With the aim of contributing to the growth of the coastal fishing industry, it was developed with the concept of improving cruising performance, safety, and operational efficiency, particularly for small fishing boats of up to three tons. The engine won customer trust by achieving the same high levels of Yamaha Motor's famed lightweight, compact, high power engine design common to its other product categories. This engine went on to serve in a wide range of uses, not only in Japan but also overseas in regions like Southeast Asia and Central and South America.
