VELVET DRIVE IN-LINE AND V-DRIVE TRANSMISSIONS (EXCEPT 5000 SERIES)
IMPORTANT: Velvet Drive In-Line and V-Drive Transmissions Only – Use of proper
rotation propeller (specified on transmission output flange rotation decal) is critical
since the transmission must be operated in FORWARD gear selector position only
to drive boat forward. If the wrong rotation propeller is installed and transmission is
operated in REVERSE to propel the boat forward, transmission failure WILL occur.
IMPORTANT: On engines which are equipped with Velvet Drive In-line transmissions,
a LH propeller is required.
Boat Construction
Engine Bed
Difference Between Starboard and Port Engine Mount 22-1/2 in. (572 mm)
Mount Adjustment Up and Down (minimum) 1/4 in. (6mm)
NOTE: Although the engine mounts allow some adjustment, ensure that the front and rear
mount locations in the vessel are in the same plane and parallel. This may be checked by
tying a string from the left front mount location to the right rear mount location and another
from right front to left rear. The strings should touch where they cross
.
