4 Installation
V-DRIVE gearbox is not flanged directly on to the engine. Make sure that the connecting cardan shaft does not transmit
vibration which could damage the transmission. V-DRIVE gearbox is installed separately, with a drive shaft and the
foundation mounting can be either rigid or elastic.
If necessary, in addition to the normal flexible coupling fitted to the engine, fit an extra damper to absorb the vibration
caused by an imperfect alignment.
4.1 Connection of the propeller shaft
We recommend using a thrust support to ease the axial stresses that inevitably bear on the marine gearbox. The per-
formance of the propeller shaft support depends on the operating loads and must be specified by the shipbuilding yard.
The alignment must be verified with the boat in the water, since the deformations of a submerged hull are capable of
altering the alignment made with the boat on the cradle.
