3. Change the engine oil and oil filter
as described on p.97-99. If there
was water in the engine crankcase,
or if the used engine oil showed
signs of water contamination, then
a second engine oil change should
be performed after running the
engine for half an hour.
4. Remove the spark plugs (p.100).
Operate the starter to expel water
from the engine's cylinders.
5. Pour 1-2 teaspoons (5-10 cm
(p.122) of engine oil into each
spark plug hole to lubricate the
inside of the cylinders. Reinstall
the spark plugs.
If the engine was running when it
submerged, there may be
mechanical damage, such as bent
connecting rods. If the engine binds
when cranked, do not attempt to
run the engine until it has been
repaired.
TAKING CARE OF UNEXPECTED PROBLEMS
6. Attempt to start the engine. Be sure
the water level is at least 2 inches
(5 cm) above the antiventilation
plate.
If you are attempting to start the
engine while the outboard motor is
out of the water, use commercially
available ear muffs and water hose to
supply water.

Running the outboard motor without
sufficient cooling water will damage
the water pump and overheat the
engine.
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 2 inches
(5 cm) above the antiventilation plate
to avoid overheating and water pump
damage.
7. As soon as possible, take the
outboard motor to an authorized
TOHATSU dealer for inspection
and service.
