N4.140

135 hp

Kubota engine base

Originating from the latest generation diesel engines developed by Kubota, the N4.140 marine engine is regarded as an ideal solution for sailing yachts as well as sport fishing boats.

Ease of use

Given its 3.8 litre cylinder capacity and its new direct injection system (E-CDIS) with its 4 valves per cylinder, the ease of use of the N4.140 will make it an ideal engine for your boat. The maximum torque is already developed at low rpm allowing you to cruise more quietly with less fuel consumption. Its two balancing shafts as well as a special piston coating further reduce the sound level and vibrations emitted by the engine.

Powerful and compact

Used on heavy sailing boats, the N4.140 proves its robustness and its reliability. Its small dimensions allow it to be fitted into compartments normally designed for engines with a lot less cylinder capacity. This engine will be your best friend during fishing trips or your offshore navigations.

Protecting the environment

The N4.140 complies with the most stringent emission regulations in the world: EU-RCD, US-EPA, BSO. The fact that the most prestigious shipyards have put their trust into this engine speaks for its quality and reliability.
