New Yanmar 6LY400 400HP Inboard Diesel Engine for sale

The new 6LY takes the all the attributes of its forerunners and adds major engineering advances. The beating heart of the engine remains the international powerboat racewinning compact 5.8 -litre in-line six-cylinder YANMAR engine block that over three decades has cemented its popularity with boat designers, builders and owners who laud its performance, fuel efficiency, reliability and smooth and quiet operation.

This latest incarnation has taken the engine into a new era of mechanical and digital sophistication. We have completely re-engineered the fuel induction and aspiration systems – all functions now being managed by state-of-the-art electronic precision for even better all-round performance. We’ve replaced single injectors with a high-pressure common-rail fuel system to deliver exceptionally finely atomised fuel to the cylinders for better power-to-weight performance, fuel economy and smooth running.

IMPRESSIVELY CLEAN AND POWERFUL PERFORMANCE

Built on 30 years of history, the 4th generation 6LY 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.
