TRANSMISSION
TROUBLESHOOTING
CONTROL
CABLES
The
majority
of
transmission
difficulties
arise
as
a
result
of
prob-
lems
with
control
cables
rather
than
from
problems
with
the
trans-
mission
itself.
A
new
cable
and
perhaps
a
new
linkage
mechanism
may
be
needed.
While
the
cable
is
loose,
shift
the
transmission
in
and
out
of
gear
using
the
actuating
lever
on
the
side
of
the
transmission
to
make
sure
there's
no
binding
inside
the
case.
If
you
experience
operating
problems
with
the
transmission,
shut
the
engine
down.
First
check
the
transmission
fluid
level,
then
have
a
helper
move
the
cockpit
shift
lever
through
the
full
range
-
from
neutral
to
full
forward,
back
to
neutral,
into
full
reverse,
and
back
to
neutral
-
while
you
observe
the
actuating
lever
on
the
transmission.
If
the
remote
is
stiff
to
operate,
break
the
cable
loose
at
the
transmission
and
try
again.
If
it
is
still
stiff,
check
the
cable
for
kinks
or
excessively
tight
bends,
and
check
any
linkage
for
binding.
If
the
transmission
passes
these
tests,
crank
the
engine
and
have
a
helper
put
it
in
forward
and
reverse
while
you
observe
the
pro-
peller
shaft;
if
the
shaft
isn't
turning,
the
transmission
needs
pro-
fessional
attention.
If
it
does
tum
but
there's
no
thrust,
check
to
see
if
you
still
have
a
propeller
on
the
end
of
the
shaft
or,
if
you
have
a
folding
or
feathering
propeller,
that
it
isn't
stuck
in
the
"no
pitch"
position.
NOTE:
If
you
suspect
a major
problem
in
your
transmission,
immediately
contact
your
WESTERBEKE
dealer
or
an
authorized
marine
transmission
facility.
