The diesel engines are designed and produced with cutting-edge technology. The propulsion engines installed on board of your yacht, after accurate designing studies by RIVA, are perfectly suitable for this kind of yacht, also thanks to the high performances they are capable of providing. You will thus be able to enjoy high performance along with full reliability, to the advantage of your navigations and your and your guests’ fun. The propulsion engines are provided with advanced electronics, in order to enhance the yacht’s performance and reducing fuel consumption and exhaust emissions. Remember, however, that operation without problems and the expected high power may be attained only if the prescribed maintenance schedule is complied with and if recommended fuel and lubricants are used.

The electronic control system of the engines provides:

Each engine is directly flanged to its sterndrive.
The engines have been installed on suitable elastic supports which absorb vibrations and enable minimum movement of the engine; in this way, the structures and the devices connected with them are not damaged.
In addition, the elastic supports allow easy adjustment of the position of the engines, either during new installation or after the expected settlement. The engines are equipped with diagnostic and monitoring electronic systems, whose aim is to check the important operating parameters of the engines and to alert the Captain in case they exceed the admitted tolerance.
