6. Do not advance the throttle‑only feature on the remote
control for starting (if equipped).
7. Turn the ignition key to the "START" position. Release the
key when the engine starts. If the engine fails to start in ten
seconds, return the key to the "OFF" position, wait one
second, and try again.
8. Check for water coming out of the water pump indicator
hole.
NOTE: The electronic starting system will automatically prime
(choke) the engine and increase idle speed for starting.
Operating the engine while overheated can cause engine
damage. If no water exits the water pump indicator hole, stop
the engine and check the cooling water intake holes for
obstruction. No obstruction may indicate a water pump failure
or blockage in the cooling system, which can overheat the
engine. Have an authorized Mercury Marine dealer check the
system.
