Prove marine technology

The new engine takes what was a very accomplished and highly popular power unit to a higher level. Like all YANMAR marine engines, it was designed expressly for marine duty.

After decades of distinguished service 6LY series engines are still regarded as some of the best in the world for cruising and workboat duty. In its transfigured form the 6LY is set to continue this tradition. Its small footprint, low height and narrow width will make it attractive for installation in new craft with ever-tighter engine-room space. Its high power density in an ultra-compact package will also make it an engine of choice for replacement not only of earlier YANMAR units, but also larger and heavier engines of similar output.
