raffreddamento chiuso Model with fresh water cooling system Questo motore può essere fornito con due tarature: 820 hp e 850 hp. Il motore è a controllo completa- mente meccanico e con il più basso rapporto pe- so/potenza al mondo. È un modello ad altissime prestazioni e rappresenta l'ultimo risultato del reparto Ricerca e Sviluppo il cui obiettivo principale è stato l'incremento dell'affidabilità e dei tempi di intervento per la manutenzione. È un motore assolutamente di serie, già adottato da enti militari per le proprie imbarcazioni di elite ed è l'ideale applicazione per barche da diporto con doti velocistiche di rilievo, validissima alternativa di motori benzina. This model can be tuned at 820 hp or 850 hp. The engine is a totally mechanic controlled engine with a unique power to weight ratio. It is a very high performance model and it represents the last result of the Research and Develop department which focused on getting a reliable engine with long maintenance schedule. It is definitely a serial engine, already adopted by the military high speed elite vessels, it is the perfect choice for high speed pleasure boats and the good alternative to gas
