BORG WARNER VELVET DRIVE
TRANSMISSION
INITIAL OPERATION
Transmission Fluid
Check transmission fluid level on the dipstick. If the
transmission has not been filled, fill with Dextron III and
continue to use this fluid. During the first 50 hours of
operation, keep a lookout for any leakage at the bell
housing, output shaft, and transmission cooler. This
fluid should be changed after the first 50 hours and
approximately every 1000 operating hours or at winter
lay-up.
NOTE:
Some transmissions are equipped with a neutral
safety switch. Unless the transmission shift lever I per-
fectly aligned in neutral the engine starter will not
activate.
Shifting Into Gear
Place the transmission selector control in Neutral before
starting the engine. Shifting from one selector position to
another selector position may be made at any time below
1000 rpm and in any order. Shifts should be made at the
lowest practical engine speed. Start the engine and
s~t
the throttle at idle speed; allow the transmission fluid to
warm up for a few minutes.
Neutral
Move selector lever to the middle position. You should
feel the detent. Center the shift lever on the transmission
through the linkage to the selector lever. With the control
in this position, hydraulic power is completely interupted
and the output shaft of the transmission does not turn.
Forward
Move selector lever to the forward position. You should
feel the detent. The shift lever on the transmission is in
the forward position. The output shaft and the propeller
shaft move the boat in a forward direction.
Reverse
Move selector lever to the reverse position. You should
feel the detent. The shift lever on the transmission is in
the reverse position. The output shaft and the propeller
should move the boat in a reverse direction (astern).
NOTE:
Moving the transmission shift lever from Neutral
Position to Forward is always towards the engine. Re-
verse is always away from the engine.
NOTE:
Be aware of any unusual noises or vibrations and
investigate to determine the cause.
NOTE: If
the boat moves backwards with the selector
control in the forward position, shut off the engine! This
problem may be the result of incorrect movement of the
shift lever by the shift control.
DAILY OPERATION
o
Check transmission fluid.
o
Visually check transmission and gear shift linkage.
o
Start engine in neutral. Allow a few minutes for fluid
to warm.
NOTE:
Too Iowan idle speed will produce a chattering
noise from the gear and damper plate. In such cases the
idle speed should be increased.
o
Shift into gear.
A
WARNING: Shifting gears above 1000 rpm can
damage the engine and transmission.
SHIFT LEVER POSITION
The selector control mechanism and linkage must position
the shift lever on the transmission exactly in Forward (F),
Neutral (N), and Reverse (R) shifting positions. A detent
ball located behind the transmission shift lever must work
freely to center the lever in each position. The selector con-
trol positions at the helm(s) must be coordinated with those
of the Velvet Drive shift lever through shift mechanism ad-
justments. An improperly adjusted shift mechanism can
cause damage to the transmission. The shifting mechanism
and transmission shift lever should be free of dirt to ensure
proper operation.
NOTE: Do not remove detent ball!
