CAUTION
Prolonged cranking intervals without
the
engine starting can resuh
In
filling the engine-
mounted exhaust system with sea water coolant. This may happen because the
sea
water
pump
is pumping sea water through
the
sea
water cooling system during crank-
ing. This sea water can enter the engine's cylinder's by way
of
the exhaust manifold
once
the
exhaust system fills. Prevent this from happening by closing the
sea
water
supply through-hull shut-off, drain the exhaust muffler, and correct the cause for the
ex-
cessive engine cranking needed
to
obtain a start. Engine damage resuhing from this
type
of
sea water entry is not a warrantable issue; the owner/operator should keep this
in mind.
