For 
safety 
reasons, 
the 
transmission 
is 
not filled 
with 
transmission 
fluid 
during 
shipment and the selector lever 
is 
temporarily 
attached 
to 
the actuating shaft. 
Before 
leaving 
the 
WESTERBEKE 
plant, each 
transmission 
undergoes 
a test 
run, 
with 
Dextron 
III ATF transmission 
fluid. 
The 
residual 
fluid 
remaining in the transmission 
after 
draining 
acts 
as 
a 
preservative. 
and 
provides protection 
against 
corrosion 
for 
at 
least 
o~e 
year 
if 
properly 
stored. 
TRANSMISSION 
FLUID 
Check 
the 
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 
25 
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 
25 
hours 
and 
approximately 
evelY 
300 
operating 
hours 
thereafter andlor 
at 
winter 
lay-up. 
A 
CAUTION: 
Be 
certain 
the 
transmission 
is filled 
and 
the 
correct 
size 
cooler 
is 
properly 
instaffed 
before 
starting 
the 
engine. 
NOTE: 
Ensure 
the 
transmission 
vent 
is 
operational. 
Remove 
seasonally 
and 
clean 
with 
carburetor 
cleaner. 
A stuck vent 
will cause pressure 
to 
build 
up 
in the transmission and cause 
jl~id 
to 
be 
forced 
out 
the 
input 
and/or shaft 
seals. 
SHIFT 
LEVER 
POSITION 
The 
gear 
shift 
control 
mechanism 
and 
linkage 
must 
position 
ihe 
actuating 
lever 
on 
the 
transmission 
exactly 
in 
Forward 
(F), 
Neutral 
(N), 
and 
Reverse 
(R) 
shifting 
positions. 
A 
detent 
ball 
located 
behind 
the 
transmission 
lever must 
work 
freely 
to 
center 
the 
lever 
in 
each 
position. 
The 
gear 
shift 
positions 
at 
the 
helm 
must 
be 
coordinated 
with 
those 
of 
the 
Velvet 
Drive 
actuating 
lever through 
shift 
mechanism 
adjustments. 
An 
• 
improperly 
adjusted 
shift 
mechanism 
can 
cause 
damage 
to 
the 
transmission. 
The 
shifting 
mechanism 
and 
transmission 
actuating 
lever 
should 
be 
free 
of dirt 
and 
well 
lubricated 
to 
ensure 
proper 
operation. 
Shifting 
Into 
Gear

posi-
tion 
may 
be 
made 
at 
any 
time 
below 
1000 
rpm 
and 
in 
any 
order. 
Shifts 
should 
be 
made 
at the

practical 
engine 
speed. 
Start 
the 
engine 
and 
set 
the 
throttle 
at

mission. 
With 
the 
control 
in 
this 
position, 
hydraulic 
power 
is 
completely 
interrupted 
and 
the 
output 
shaft 
of 
the 
transmis-
sion 
does 
not turn. 
NOTE: 
Some 
transmissions 
are 
equipped 
w.ith 
a neutral 
safety 
switch. 
Unless 
the

The 
actuating 
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 
the 
gear 
shift 
lever 
to 
the reverse 
position. 
You 
should 
feel 
the

the 
reverse position. 
The 
output 
shaft 
and 
the 
propeller 
should 
move 
the boat 
in 
a 
reverse 
direction 
(astern). 
NOTE: 
Moving 
the 
transmission 
actuating 
lever
