Exhaust Elbow Installation 
The  Westerbeke  Corporation  offers  a 
45° and 
90° 
exhaust  elbow  as 
well 
as an  exhaust riser 
you 
can 
install 
on 
your  engine.  Refer 
to 
the  instructions 
below 
when installing the exhaust elbow purchased. 
NOTE: 
Fabricated exhaust elbows or risers attached 
to 
the exhaust manifold must not exceed 8 Ibs when 
unsupported. 
L  Coat only one side 
of 
the exhaust  gasket with 
High  Tack  adhesive  sealant  (manufactured 
by 
Permatex  Company,  Brooklyn,  NY).  Place  this 
coated  surface  against  the  exhaust  manifold's 
exhaust  port  flange  (the gasket  should stick 
to 
the 
flange without falling 
off). 
2. 
Place  the  clamp  over  the  elbow's  flange.  Place 
your  exhaust elbow  against  the  exhaust manifold's 
flange 
so 
the exhaust  manifold's flange  rests  snug 
against  the  exhaust  elbow's flange  with  the  gasket 
centered  between  the 
two. 
Now 
slip  the  exhaust 
clamp over both flanges. 
3. 
Tighten the  clamp  just  enough 
so 
the exhaust 
elbow 
can remain attached 
to 
the  manifold and still 
be 
rotated. 
The  exhaust  elbow  discharge 
must 
be 
directed 
downward 
so 
the mixture of raw water  and exhaust 
gases  will  flow/fall  downward  into  the  exhaust 
mnlller which 
must 
be positioned below the exhaust 
elbow. 
There shonld  be 
no 
loops  or  rises  in  the 
exhaust  hose  connected between  the exhaust  elbow 
and  the  mnlller,  as  these  would  trap  water  and 
possibly  allow  water 
to 
flow  back into  the engine 
during starting or at shut 
down. 
4. 
Adjust  the  elbow 
by 
rotating 
it 
until  the  desired 
alignment with the exhaust piping is acquired. 
5. 
Carefully tighten the clamp between 8 
to 
10 
Ib-ft, 
or 
96 
to 
120 
Ib-in., or 
LI 
to 
1.3  kg-m. 
II 
CAUTION 
II 
Approach the 
10 
lb-ft  torque  limit 
with caution.  The clamp's threads 
will  break 
if 
more  than 
10 
Ib-ft 
is 
applied 
to 
the clamp. 
If 
a leak exists, correct it immediately.
