6.420TDI
Toyota engine base

The design of the 6.420 TDI is based on the 6 cylinder diesel engine which is used and tested on the Land Cruiser 4x4. The robustness of its engine block and its cast iron cylinder head as well as the efficiency of the different heat exchangers that compose the marinization developed by Nanni Diesel give you the assurance of quality, reliability and longevity that have already convinced many renowned boat builders.
Smooth and performing
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 vibrationfree comfort.
The 6.420TDI is perfectly suited for shaft line boats as a result of the combination of its low rated speed of 3600 rpm, 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.

Compact and powerful
The power to weight ratio of this 320 horsepower 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 motorization with plenty of power reserve for all situations.

Protecting the environment
The engine complies with the most stringent emission regulations in the world : EU-RCD, US-EPA and BSO.
