New Yanmar 6LY400 400HP Inboard Diesel Engine – Sale !!
inboard engine – The latest 6LY engine model builds upon the solid foundation established by its predecessors, incorporating significant advancements in engineering. At its core, it retains the renowned 5.8-liter inline six-cylinder YANMAR engine block, a trusted choice for powerboat racing with a legacy spanning over thirty years. This engine is celebrated by boat designers, builders, and owners for its exceptional performance, fuel efficiency, reliability, and quiet, smooth operation.
This new version ushers the engine into a new era of advanced mechanical and digital technology. The fuel induction and aspiration systems have been entirely re-engineered, now leveraging cutting-edge electronic precision to enhance overall performance. The previous single injectors have been replaced with a high-pressure common-rail fuel system, which provides finely atomized fuel to the cylinders, improving power-to-weight ratio, fuel economy, and operational smoothness.
OUTSTANDINGLY CLEAN AND POWERFUL PERFORMANCE
Building on three decades of engineering excellence, the fourth-generation 6LY engine offers a robust and smooth operation. Featuring an advanced Denso common rail fuel injection system, this engine delivers superior fuel efficiency and reduced noise compared to earlier models. Its high torque across the operating range ensures exceptional acceleration and responsive performance.
The engine’s compact and lightweight design allows for easy installation in constrained engine compartments, making it an ideal choice for both retrofitting existing vessels and equipping new ones.
