Engine: MAN i6 800hp

MAN presents its latest generation of six-cylinder engine designed to be used in yachts and trawlers up to seventeen meters in length, 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 six-cylinder in-line engine 800hp i6-800 has a cylinder capacity of 12.4 l available for light duty operations.  The future-proof i6-800 yacht engine is based on the D2676 model, also have a modern common rail system offering up to 1800 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 and the International Maritime Organization.  The new yacht engines also offer the broad torque plateau that is characteristic for MAN marine engines generating 2700 Nm at between 1200 and 2100 rpm. This provides maximum torque over a broad engine speed range at the lowest specific fuel consumption, achieving consistent acceleration and a fast and efficient planing.  MAN’s design engineers came up with an optional design cover for the six-cylinder engine, ensuring to fulfil the criteria of elegance and high performance. The sophisticated and timeless design of the perfectly shaped engine stays within the style of modern luxury yachts.  For naval architects the new six-cylinder inline engines come in MAN’s typically compact 1800 x 922 x 1103 mm design and have an even more streamlined oil pan design. With a dry weight of 1200 kg, the new generation of engines also has an improved power to weight ratio.  The the MAN marine diesel engines i6-800 is based on the D2676 and is set to replace the predecessor model R6-800 based on the D2876 in the medium term.
