the engine into the classic engine-cooling version of marine engines is omitted. Installation of the unit onto the deck
is possible.

The very compact engine design and
the flexibility of the positioning of the
unit reduce the installation costs.

The robust engine design allows world-

Low fuel consumption, low mainte-

wide operation even with high sulphur
