A Tough, Reliable Engine

Toughness and reliability have moved ahead in large steps thanks to the steady progress of technology. Modern technology makes possible the hi-tech iron block and head, the special surface treatment of the cylinder liners, the advanced design of the water cooled manifold – in fact a whole host of new features which add sustainability to the overall toughness and reliability of this engine.

This engine features a stronger cylinder block and cylinder head, stronger head bolt bosses, stronger cylinder liner rack for uniform rack face pressure, stronger main bearing caps. Cylinder wear and lube oil consumption are both reduced by the specially treated cylinder liners, and by the nitrided SUS rings.

Design

Light weight, compact with a flat top and a low profile, the installation of this large capacity, high power engine is now possible in smaller vessels.

Easier Routine Inspection, Easier Maintenance

Large inspection windows on the side of the block allow in-site replacement of pistons. Full mechanical engine management avoids the chance of delicate and expensive electronics failing in hot, marine engine room conditions. Maintenance is simplified, inspection and replacement costs are lower. Reliability and durability are enhanced. Engine is user friendly.
