N3.30

29 hp

Experience & Know-How

Kubota engine know-how combined with the marinizing experience of the Nanni Diesel engineering team has made the N3.30 the preferred choice of the greatest skippers to accompany them in races around the world.

Environmental-Tri Vortex Combustion System (E-TVCS)

The N3.30 is equipped with the E-TVCS combustion and injection system which considerably reduces particulate emission and smoke while dramatically improving fuel efficiency.

Reliability and longevity

A new casting technology which has been developed by Kubota for their engine blocks has resulted in reduction of the average operational temperature during heavy duty operation. This evolution combined with the Nanni Diesel marinization increases longevity and reliability, while still employing timing gears rather than a timing belt which results in significantly decreased maintenance time and cost. Moreover, the SOLAS (Save Our Lifes At Sea) certification serves as additional proof of the Nanni Diesel technical know-how applying the most stringent safety standards currently in effect for lifeboats to this engine.

Electricity and on board comfort

A complete range of electrical generators developed by Nanni Diesel enables the N3.30 to supply all the electricity required for comfort equipment and electronic navigation devices on board.

Protecting the environment

The N3.30 complies with the most stringent emission regulations in the world: EU-RCD, US-EPA., BSO
