Pleasure boats: Operating with full performance, restricted by 5 % of the entire max. 400 hours per annum. Normaly not more than 80 % of full performance.
Semiprofessional use: Operating with full performance, restricted by 5 % of the entire max. 400 hours per annum. Use during longer time on not more than 75 % of maximum rotation speed.
Continuous duty: Operating with full performance, restricted by 5 % of the entire max. 2.500 hours per annum. Use during longer time on not more than 80 % of the maximum rotation speed.
It is important to synchronize the engine, the gearbox-reduction and the propeller with each other so that the engine has no difficulties to reach the indicated maximum rotation speed.

All VELVET DRIVE hydraulic gearboxes are designed with a flange SAE 7 with interleaving 26 T 20-40 DP at the front side .

VELVET DRIVE gearboxes need ATF oil (Transmission Automatic fluid) according to specification C3. In case of engine speed does not exceed 3000 rpm, a SAE 30 oil can be employed on request .
