H4.150
Comfort through innovation

The Nanni Diesel 4-cylinder engine H4.150 has been developed taking advantage of the latest improvements in terms of modern diesel engines.
Endowed with an electronically controlled Common Rail direct injection system, 4 valves per cylinder, a turbo compressor and two balancing shafts, this engine ensures upscale performances and complies with the most stringent emission regulations in the world, while maintaining low values of fuel consumption.

Saving space and weight
Designed to fi t into the smallest engine compartments, this 150 horsepower engine benefits from an advantageous power to weight ratio, and makes easy its onboard installation and its maintenance.
The compact marinization, along with the design of the lubrication, cooling and air systems, have made possible to signifi cantly reduce the size of the propulsion package.

Dynamic and responsive
The high revolution speed of the H4.150 engine is particularly well adapted to fast and planning hulls, both in shaft line and Stern Drive versions, while its idle speed of 700 rpm facilitates the manoeuvres in the marina.
Protecting the environment
The combination of a common rail fuel injection system with a marinization optimising the intake air and exhaust gaz flows allows this engine to comply with the stringent EPA Tier 2 and EU-RCD emissions regulations.
