yanmar 4lha-stp diesel engineYANMAR 4LHA-STP - 240hp
The high power configuration comfortably allows this engine 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 designed for use with a variety of marine gearboxes, including straight, angled and vee- drive units. The turbocharger has a waste- gate boost compensator which improves acceleration (4LHA- STP).

Environmentally Engineered
This engine shares all the benefits of Yanmar's commitment to protecting the environment in which we live with features such as:

  • low noise, low vibration, highly economical use of fuel.
  • low smoke, especially when accelerating or idling.
Vibration has been kept at a low level due to the use of special steels in the block and other critical areas. Being substantially slimmer configuration means easy installation and easy serviceability, even in tight locations. Repowering in most instances is straight- forward; the total package being slimmer, shorter and less bulky than previous models.
