TAKING CARE OF UNEXPECTED PROBLEMS
If the engine fails to start, remove
the spark plugs and 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 two inches
above the antiventilation plate to
avoid overheating and water pump
damage.
7. As soon as possible, take the
outboard motor to an authorized
Honda marine dealer for
inspection and service.
