Nanni Marine Diesel Engine N2.14

14 hp

Kubota Engine Base

Nanni Diesel has forged a strong partnership with Kubota. Kubota engines are known for their robust design, great reliability and excellent longevity. The N2.14 is equipped with a fast preheating system improving start-up time even at low outside temperatures.

New Injection System

The N2.14 has less particulate emission and smoke due to the improved combustion and injection system E-TVCS (Environmental-Tri Vortex Combustion System). This combustion chamber design optimises the engine efficiency, resulting in excellent onboard comfort and reduced fuel consumption.


The N2.14 offers several onboard installation options making it suitable for a vast variety of boats. Repowering your boat is a breeze with our installation kits which are specifically designed to eliminate the need to modify the frame of your existing engine compartment.

Saving space and weight

Due to its excellent power to weight ratio, the N2.14 is the perfect propulsion choice. Its small dimensions as well as the optional gearbox or sail drive transmission ease its onboard installation on motor boats with limited space as well as on small sailing boats or cruising boats.

Protecting the environment

The N2.14 complies with the most stringent emission regulations in the world: EU-RCD, US-EPA, BSO.
