The best engine in its class just got better. The high power configuration comfortably allows the 4LHA to stand world class in all three main areas of comparison namely:
- Power-to-weight ratio
- Power-to-displacement ratio
- Power for a given set of engine dimensions
The 4LHA is suitable for both recreational marine and light-duty commercial applications, and has been designed for use with a variety of marine gearboxes, including straight, angled and vee-drive, Kanzaki and ZF-Hurth units. The turbocharger has a waste-gate boost compensator which improves acceleration (4LHA-STP).
This engine shares all the benefits of Yanmar’s commitment to protecting the environment in which we live. Features such as low noise, low vibration, highly economical use of fuel, low smoke, especially when accelerating or idling, ensure Yanmar continues to lead the way in low emission technology.
Vibration has been kept at a low level due to the use of special steels in the block and other critical areas. Being a substantially slimmer configuration means easy installation, even in tight locations. Repowering in most instances is straight-forward; the total package being slimmer, shorter and less bulky than previous models.
