engine ush out procedures if
not followed in accordance to their specic
instructions can result in costly engine dam-
age. Follow MerCruiser’s specic instructions
for ush-out procedures located in the Engine
operator’s manual. Consult engine manu-
factuer’s authorized service center for addi-
tional assistance should further questions
arise.
Make sure that no section of ush 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 ooding of the engine
compartment. Periodically check hoses for
abrasions.
