the 
inside 
face 
with 
a 
metallic 
object, 
such 
as 
a 
screwdriver. 
Clean 
them 
and 
reinstall. 
Usually, 
there 
are 
four 
plugs 
in 
the 
bottom 
part 
of 
the 
main 
housing. 
Only 
two 
of 
these 
are 
magnetic. 
The 
other 
two 
need 
not 
be 
removed 
(see 
illustration).

The 
Zerk

on 
the 
external 
uni-

of 
the

marked 
"Water

On 
the 
RV-IO

one 
of 
the 
water 
lines 
going 
into 
the 
#6 
water-cooled 
bottom 
cover 
must 
be 
disconnected 
to 
drain 
the 
water.

REALIGNMENT 
When 
the 
boat 
is 
launched 
after 
being 
in 
drydock, 
the 
line-up 
of 
the 
v-drive 
to 
the 
propeller 
shaft 
flange 
and 
the 
engine 
to 
the 
V-
drive 
should 
be 
rechecked 
and 
corrected 
if 
necessary. 
Some 
engines 
with 
rubber 
mounts 
may 
sag 
and 
must 
be 
raised 
with 
adjustments 
or 
shims 
for 
proper 
alignment 
(see 
"Flange 
Alignment" 
and 
"Engine
