Series Information

YANMAR’s fourth-generation 6LY-CR marine diesel series builds on the virtues of its classic six-cylinder forerunners, advancing efficiency and lowering emissions.

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 engines are still regarded as some of the best in the world for cruising and workboat duty. In has been transfigured into the 6LY-CR and 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.

Features:

  • Part of Yanmar’s best in class Common Rail engine line up
  • A proven solution for jet and shaft drives
  • Compact, lightweight and powerful
  • Certified for recreational and light duty commercial applications
  • High torque on the low-end and over the power band, delivering leading acceleration and top end responsiveness
  • 4th generation reliability for proven performance
  • Designed for efficient installation and refitting

 

 

Impressively Clean and Powerful Performance

Built on 30 years of history, the 4th generation 6LY-CR is a smooth and robust 6 cylinder in-line engine, producing impressively clean and powerful performance.

Incorporating an advanced Denso common rail fuel injection system, the 6LY-CR delivers excellent fuel economy and significantly less noise than previous generations, while the high torque output throughout its full operating range produces class leading acceleration and responsive performance.

Its narrow and lightweight profile enables installation in the tightest of engine rooms, making it the perfect solution for repowering, as well as newly built vessels.

 

Electronic Integration

The new 6LY-CR has taken the engine into a new era of mechanical and digital sophistication. YANMAR have completely re-engineered the fuel induction and aspiration systems, with all functions now managed by state-of-the-art electronic precision for better all-round performance.

YANMAR have replaced single injectors with a high-pressure common-rail fuel system to deliver exceptional finely atomised fuel to the cylinders for better power-to-weight performance, fuel economy and smooth running.

 

Fingertip Control

For the ultimate in easy and precise boat control, YANMAR offers the latest VC10 ‘fly-by-wire’ vessel control system to give precision gear changing and throttle adjustment with perfect ‘feel’. And with the joystick control option as part of a fully-integrated YANMAR engine and controls package, docking is also really easy.
