Yanmar 6LY440 Powerboat Engine

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

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 race-winning 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-engi-neered the fuel induction and aspiration systems – all functions now being managed by state-of-the-art electronic precision for even better all-round performance.
