the spark plug hole, and then pull
the starter grip several times to
lubricate the inside of the cylinder.

the emergency stop switch clip into
the emergency stop switch.
7. Attempt to start the engine.
If the engine fails to start, remove
the spark plugs, dry them, then
reinstall the spark plugs and
attempt to start the engine again.
If the engine starts, and no
mechanical damage is evident,
continue to run the engine for a half
hour or longer. Be sure the water
level is at least 2 inches (5 cm)
above the antiventilation plate to
avoid overheating and water pump
damage.
8. As soon as possible, take the
outboard motor to an authorized
Honda Marine dealer for inspection
and service.
