MAN Engines is set to present its latest generation of six-cylinder engines at the Fort Lauderdale Boat Show in Florida, USA. These engines are designed to be used in yachts and trawlers up to 55 feet, as well as in sport fishing boats. The basic six-cylinder engine has been tried and tested many hundreds of thousands of times in a wide range of on- and off-road machinery since it was first introduced in 2007. Modified especially for the use in pleasure craft, the two six-cylinder inline engines, the 537 kW (730 hp) i6-730 and the 588 kW (800 hp) i6-800, each with a cylinder capacity of 12.4 l, are currently available for light duty operations.

The future-proof i6-800 and i6-730 yacht engines, which are based on the D2676 model, also have a modern common rail system offering up to 1,800 bar for high mean pressures and optimized combustion. This enables MAN engineers to achieve lower vibrations and noise emissions along with reduced fuel consumption. To ensure compliance with strict emissions legislation, MAN shares information and data on a regular basis with institutions including the US Environmental Protection Agency (EPA) and the International Maritime Organization (IMO).
