Exhaust Elbow Installation
The Westerbeke Corporation offers a 7Z' exhaust elbow as well as an exhaust riser you
can install on your engine's exhaust manHold. Refer to the instruction below when installing
the exhaust elbow purchased for your generator.
NOTE: Fabricated exhaust elbows or risers attached to the exhaust
manHold shall not exceed 8 Ibs when unsupported.
1.
Coat only one side of the exhaust
gasket with "High Tack" (Manufactured
by Permatex Company, Brooklyn, N.Y.)
adhesive sealant. Place this coated sur-
face against the exhaust manHold's ex-
haust 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 manHold's flange so
the exhaust manHold'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. A Tighten the clamp just enough

so the exhaust elbow can remain attached to the manHold and still be rotated.
B. The exhaust elbow discharge ~ be directed downward so the mixture of raw
water and exhaust gases will flow/fall downward into the exhaust muffler which must be
positioned below the exhaust elbow. There should be no loops or rises in the exhaust
hose connected between the exhaust elbow and the muffler, 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 2 to 3 Ib-It, or 24 to 35 Ib-in, or 0.27 to
0.41 kg-m.

Approach the 3 Ib-It torque limit with caution. The clamp's threads will
break H more than 3 Ib-It is applied to the clamp.
If a leak exists, correct it immediately .
