Installation manual

BORG WARNER VELVET DRIVE TRANSMISSION
MAINTENANCE
Transmission maintenance is minimal. Keep the exterior
housing clean, check the fluid level as part
of your regular
routine, and change the fluid every 300 operating hours.
Periodically inspect the transmission and the cooler for leaks
and corrosion. Make certain the air vent is clear and when
checking the fluid level look for signs
of water contamination
(fluid will appear as strawberry cream).
Lay-up/Winterize
Storage requires special care. Follow these procedures:
o Drain the water from the transmission oil cooler and
replace it with a proper mixture
of antifreeze coolant.
NOTE: This operation will usually occur when the engine
raw water cooling system is properly winterized.
o Clean up the transmission and touch-up unpainted areas
(use heat resistant paint).
o Fill the transmission with Dextron III ATF fluid to pre-
vent internal corrosion.
o Loosen attaching hardware from the transmission
output flange and propeller shaft coupling flange before
removing the boat from the water. Separate the flanges
and spray with lubricant.
o Inspect the gear shift cable, linkage, and attachments.
Look for corrosion
of the end fittings, cracks or cuts in
the conduit, and bending
of the actuator rods. Lubricate
all moving parts.
NOTE: If the transmission is to be stored for a long time
(twelve months or more), it should be topped off with
fluid
to prevent internal corrosion. Reduce the fluid level
before putting the engine back into service.

BORG WARNER is aware of the shock loads that can be
placed on its gears as the result of mechanical propeller oper-
ation
or fully reversing of the propeller blades while shiftIng.
Therefore torque loads and directional changes should be
made at low engine speeds.
If it is found that a failure was
caused by a shock load, any warranty claim
wiJI be denied.
A CAUTION: System-related noises or vibrations can
occur at low engine speeds which can cause gear rattle
resulting In damage to the engine and/or transmission.
BORG WARNER Is not responsible for total system-
related torsional vibration of this type.
If any problems occur with the transmission, see
TRANSMISSION TROUBLESHOOTING in this manual.
