The D3 with 110 hp is an inboard engine optimised for large sailing boats and displacement motor boats. The engine is very compact and at 215 kg its weight is extremely low, thanks to the all-aluminium base engine.

Performance is excellent with high torque at low revs for easy manoeuvring. Low cruising rpm means excellent onboard comfort with minimal vibrations and sound.

The basic design
The basic design is a straight, 5-cylinder diesel engine with turbo and charge-air cooler. Five cylinders generate uniform and smooth propulsion without the need of balance axles.

Rated speed is at only 3,000 rpm which means that the D3-110 operates at low revs. This gives excellent onboard comfort with low sound and vibrations. Low cruising rpm also means that it is possible to use a larger propeller, which improves efficiency and further reduces noise and vibrations.

4-valve technology with common rail system
The fuel system is electronically controlled common rail high-pressure fuel injection, working at a pressure of 1,600 bars. Twin manifolds per cylinder, combined with 4-valve technology, ensure efficient fuel flow. The manifolds are also located one on each side, resulting in a rapid mix of fuel and air.

Variable geometry turbo with aftercooler
The Variable Geometry Turbine (VTG) turbocharger on the new D3 has flexible blades that can be angled, thereby changing the geometry or the size of the turbo as required. The blades are controlled electronically and the control unit can quickly and precisely adapt the turbo to give maximum power in any situation.

…and compact
The D3-110 is efficiently packaged. The external components are placed so as to make the engine a more compact unit. Each part is designed according to the space available. For example, we have developed an entirely new type of heat exchanger, which is divided in order to occupy less space. The divided flywheel, with inbuilt power balance, means that there is no need for damping in the transmission, which saves 10 centimetres in length.

Low emissions
The common rail system in combination with an advanced combustion system sets new standards for minimizing exhaust emissions.

The D3-110 is a modern, low-emission engine that complies with the emission requirements introduced in the EU and USA as from 2006.Start-up and acceleration smoke is reduced to a minimum.

EVC – Electronic Vessel Control
EVC with mechanical shift and throttle is the new common platform for engine and driveline control, instrumentation, accessories and efficient servicing. It offers a higher level of integration with your boat: speed, tank level, depth and surface water temp as well as trip computer integrated with uniform instrumentation are some of the exciting new features offered by EVC.


Minimal need for maintenance
The new D3-110 requires a minimum of maintenance thanks to features such as:
- The camshaft and freshwater pump are driven from the
crankshaft with a toothed belt with automatic tensioner.
- The seawater pump, servo and alternator are all driven by
a twin side Poly-vee belt with belt tensioner for easy
adjustment.
- Hydraulic lash adjusters for automatic valve clearance
, no manual adjustment is needed

140 A alternator
Modern boats tend to carry more and more power consuming features such as navigators, autopilots, fridges, etc. The new D3-110 features a powerful 140 A alternator with an integrated temperature compensated regulator. Together, they provide high charging capacity for single or multiple battery banks.

Freshwater cooling standard
The D3-110 is fitted with freshwater cooling as standard. This optimises engine working temperatures for greater efficiency and reduced maintenance. The cooling channels are constantly flushed with protective fluids rather than corrosive salt water.

Ready prepared hot water outlet allows for simple connection to a calorifier as part of a hot water system. Water heating is quick and efficient, thanks to the higher temperatures generated with a freshwater-cooled system, while the time and cost of calorifier installation are also reduced.
