General
Water-cooled exhaust lines should be used in all marine
installations. The hose used for the lines should have a
2 in. (51 mm) inside diameter. Keep the lines as short
and straight as possible. The use of two hose clamps on
each end of flexible exhaust hose connections is highly
recommended. ABYC Safety Standards P-1.6.c
recommend a pitch of at least 1/2 in. (12.8 mm) per
running foot (30.5 cm). Use flexible steam hose
conforming to UL Standard 1129 for “Engine wet
exhaust components” between the mixing elbow and
the exhaust outlet. A silencer should be independently
mounted to eliminate any stress on the exhaust system
and exhaust manifold/mixer elbow. See Figure 6-16 for
the exhaust connection to the mixer elbow.
