The design of the 6.420TDi is based on the 6 cylinder diesel engine which is used and tested on the 4×4 Land
Cruiser. The robustness of its engine block and its cast iron cylinder head as well as the efficiency of the
different heat exchangers that makes up the marinisation developed by Nanni Diesel gives you the assurance of
quality, reliability and longevity that have already convinced any renowned boat builders.
The 6.420TDi boasts 6 in-line cylinders, 4 valves per cylinder and 2 balancing shafts which result in
unprecedented smoothness providing very quiet and virtually vibration-free comfort.
The 6.420TDi is perfectly suited for shaft line boats as a result of the combination of its low speed of 3600rpm,
its 4.2 litres capacity and its high torque at low speed. The hole-shot of your boat is quicker and the obtained
cruising speed at low rpm ensures low fuel consumption.
The power to weight ratio of thsi 320hp engine is one of its greatest advantages. Its reduced dimensions ease
installation and have already made it a preferred option on numerous boats. With this engine you can count on
the most dynamic motorisation with plenty of power reserve for all situations.
The engine complies with the most stringent emission regulations in the world – EU-RCD, US-EPA and BSO.
