optimum mounting height. Consult your
Yamaha dealer or boat manufacturer for fur-
ther information on determining the proper
mounting height.
1. Idle hole
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.
