M 43 C Marine Propulsion Engine

M 43 C Marine Propulsion Engine

Since its introduction into the market, the MaK long-stroke engine series M 43 has achieved an outstanding position on the marine applications market as an in-line engine in 6, 7, 8 and 9 cylinder versions. More than 650 engines with a total power of more than 6,500 MW have already been sold making the M 43 the market leader in the 5–9 MW power class. All the cylinder configurations have contributed to this market success. More than 90% of the marine engines run on heavy fuel within IMO regulatory limits.
