General
Water-cooledexhaustlinesshouldbeusedin all marine
installations. The hose used for the lines should have a
2 in. (51 mm) inside diameter. Keep the lines as short
andstraightas possible. The useoftwohose 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.
