Propeller Rotation
ZF MARINE 630 AND 800 AND VELVET DRIVE 5000 SERIES TRANSMISSION
The ZF Marine 630 and 800 and Velvet Drive 5000 Series transmissions are full power
reversing transmissions, allowing a standard LH rotation engine (viewed from flywheel end)
to be used for both propeller rotations. Propeller rotation (output flange rotation) is
determined by shift cable attachment at the remote control.
