8LV Series Shaftdrive 320-370 mhp @ 3800rpm

Yanmar has developed a new 4.46 litre twin-turbo V8 diesel engine, coupled to a sterndrive or gearbox.  The 8LV is offered at 320 mhp (239 kW) and 370 mhp (272 kW).  You will be impressed by the amazingly low noise levels and the smooth ride and the V8 diesel engine adds in all of those renowned Yanmar qualities of performance, reliability, durability and respect for nature and you have an engine that pushes marine standards to a new high.

  • Extremely high power, gripping acceleration and big torque
  • Designed for fuel economy
  • Low noise and vibration
  • Benefits from Yanmar’s VCS CAN-bus vessel control system
  • Twin-turbo V8 diesel with common-rail fuel injection
  • EPA Tier 3 compliant.

Engine Model

  • 8LV-320  320 mhp @ 3800rpm
  • 8LV-370  370 mhp @ 3800rpm

Gear Option

  • KMH50A (Down Angle 8°)  Ratio  2.13 / 2.43
  • KMH52V (V-drive 12°)  Ratio 1.58 / 2.08 / 2.47

The compact 8LV diesel can be installed in single or twin configuration, with KMH50A series, down angle or KMH52V, V-drive transmissions.

A key feature of the high torque 8LV is its wide power band.  It idles at 550 rpm, capable of crawling speed in the marina, aided further by KMH drive systems.  Maximum engine speed is 3,800 rpm – well ahead of other engines in this segment.

It has a twin turbocharger and common rail fuel injection for superior performance in terms of fuel economics and acceleration.  There are four valves per cylinder.  In the Yanmar tradition of high power from low weight, dry engine weight is just 450 kg.

This is the first engine to use Yanmar’s own, newly developed CAN-bus vessel control system, the Yanmar VCS.  It can be ordered with the new joystick, facilitating 360º turn, sideways and diagonal movement.

Further benefits are exceptionally low noise levels and minimized vibration, ease of installation and servicing, and the advantage of a powerful 12V / 180A alternator.

The 8LV is expected to attract a wide variety of boat builders producing craft up to 45-feet (14 metres) for applications ranging from water skiing to cruising.  Additionally, the engine will be used for repowering, offering the advantages of diesel over similar-sized V8 gasoline units.
