With an engine speed range up to 3.000 rpm, the SDI 50-4 offers some additional thrust whenever needed, e.g. for steaming against wind and seas. The overall engine speed level is still low, but slightly higher than in the case of SDI 40-4 as a lower-pitched propeller is needed in order to let the engine arrive at the rated 3.000 rpm and 37 kW (50hp).
Easily meets EU standards and all expected future emission standards for marine engines.
