ECM01635
NOTICE
Make sure that the idle hole is high
enough to prevent water from entering
the engine even if the boat is stationary
with the maximum load.
Incorrect engine height or obstructions
to the smooth flow of water (such as the
design or condition of the boat, or ac-
cessories, such as transom ladders or
depth finder transducers) can create air-
borne water spray while the boat is
cruising. If the outboard motor is oper-
ated continuously in the presence of air-
borne water spray, enough water could
enter the engine through the air intake
opening in the top cowling to cause se-
vere engine damage. Remove the cause
of the airborne water spray.
