12. MAINTENANCE
Periodic maintenance and adjustment
are important to keep the outboard
motor in the best operating condition.
Service and inspect according to the
MAINTENANCE SCHEDULE.
Shut off the engine before
performing any maintenance. If the
engine must be run, make sure the
area is well ventilated. Never run
the engine in an enclosed or
confined area. Exhaust contains
poisonous carbon monoxide gas;
exposure can cause loss of
consciousness and may lead to
death.
Be sure to reinstall the engine
cover, if it was removed, before
starting the engine. Lock the 
engine cover fixing lever securely
(see page 59).
• If the engine must be run, make
sure there is water at least 100
mm (4 in) above the
anticavitation plate, otherwise
the water pump may not receive
sufficient cooling water, and the
engine will overheat.
• Use only Honda Genuine parts or
their equivalents for
maintenance or repair. The use of
replacement parts which are not
of equivalent quality may
damage the outboard motor.
