CHANGING
THE
TRANSMISSION
FLUID

for
the
first time after about
25
hours of
operation, then every
250 operating hours or
at
least once a
year or when
you
change engine
fluid.
Check
for
leaks
and
make a visual inspection of the shift cables and shaft
coupling. Push a suction pump hose down through
the
dipstick hole
to
the
bottom of
the
housing
and
suck out
the
fluid.
(If
space allows, use the transmission drain). Remove
the drain plug
from
the bottom of the transmission

OR
BEING
TOWED
Rotation of the propeller without a load, such
as
when
the
boat
is
being sailed, being towed or anchored
in
a
river,
as
