6. Ignition key starting ‑ Turn ignition key to the START position and release
the key. The electronic starting system will automatically crank the engine
for starting. If the engine fails to start, the engine will stop cranking. Turn
the key to the START position again until engine starts.
NOTE: For initial start of a new engine or for an engine that ran out of fuel or
was drained of fuel, the fuel system should be filled as follows:
Turn the ignition key switch to the ON position for approximately five seconds.
Turn the key to the START position and release it, the engine will crank for a
maximum of eight seconds. The engine may start, run rough, and stall while
filling the system. Repeat this starting procedure until the engine remains
running. Allow the starter motor to cool for 20–30 seconds between start
attempts.
7. After the engine starts, check for a steady stream of water flowing out of
the water pump indicator hole.
IMPORTANT: If no water is coming out of the water pump indicator hole, stop
the engine and check the cooling water intake for obstruction. No obstruction
may indicate a water pump failure or blockage in the cooling system. These
conditions will cause the engine to overheat. Have the outboard checked by
your dealer. Operating the engine while overheated will cause engine damage.
8. If the engine does not start, push the throttle only button in and advance
the remote control handle slightly to open the throttle. Crank the engine
and be prepared to immediately reduce the throttle after the engine has
started.
