Comfort on board guaranteed thanks to quieter navigation. Here is one of the major advantages of the MAN V12-1650 12-cylinder V engine. Due to its characteristics, it is particularly suitable for yachts and pleasure boats from 50 to 100 feet.
Its weight/power ratio of 1.45 kg per HP, thanks to its low weight (2,400 kg), helps to ensure excellent efficiency, which is why the engine is ideal for those who like to sail comfortably during the night to cover long distances.
Another advantage is represented by the second-generation common rail direct injection system, which has a positive impact on:
- make the engine quieter;
- improve acceleration;
- ensure more comfortable driving by reducing fuel consumption.
Finally, its compact dimensions and modern exhaust system make the V12-1650 engine more easily installable, also reducing maintenance costs.
