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!
