M 32 E Marine Propulsion Engine

Caterpillar Motoren designed the M 32 E based on the reliable M 32 C engine series. The M 32 E will share the same footprint as the successful M 32 C. The M 32 E is the first MaK 5 MW engine in the 320 mm bore segment. The new design still supports operation at any ambient condition without load reduction.
