4 Installation
If the reverse transmission is not flange-mounted directly onto the engine, check that the connecting cardan shaft does
not transmit dangerous vibrations to the transmission.
If the reverse transmission is installed separately with the universal joint, it can be fastened to the base both elastically
and rigidly (V-DRIVE).
If necessary, besides the normal flexible coupling applied to the engine, install a further element capable of absorbing
the vibrations caused by imperfect alignment.
4.1 Connection of the propeller axle
We recommend using a thrust support to ease the axial stresses that inevitably bear on the reverse transmission. The
performance of the propeller axle support depends on the operating loads and must be specified by the shipbuilding
yard.
The alignment must be verified with the watercraft in the water, since the deformations of a submerged hull are capa-
ble of altering the alignment made with the watercraft on the cradle.
