engine flush out procedures if
not followed in accordance to their specific
instructions can result in costly engine dam-
age. Follow MerCruiser’s specific instructions
for flush-out procedures located in the Engine

tional assistance should further questions
arise.
Make sure that no section of flush hoses is
in contact with moving or hot engine parts or
abrasive surfaces such as screw threads,
sharp edges, etc., which could damage the
hoses. Damage to the hoses could cause
leaks and possible flooding of the engine
compartment. Periodically check hoses for
abrasions.
