Exhaust Elbow Installation
The Westerbeke Corporation offers a 45 0 and 90 0 exhaust
elbow as well as an exhaust riser you can install on your
propulsion engine. Refer to the instructions below when
installing the exhaust elbow purchased for your generator.
NOTE: Fabricated exhaust elbows or risers attached to the
exhaust manifold shall not exceed 8 Ibs when unsupported.
1. Coat only one side of the exhaust gasket with "High Tack"
adhesive sealant. 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.A. Tighten the clamp just enough so the exhaust elbow
can remain attached to the manifold and still be rotated.
B. The exhaust elbow discharge must 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 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 causing internal damage to the engine.
4. Adjust the elbow by rotating it until the desired alignment
with the exhaust piping is acquired.
