Submerged Motor

A submerged motor must be serviced
immediately after it is recovered
from the water in order to minimize
corrosion.
If there is a Honda outboard motor
dealer nearby, take the motor
immediately to the dealer. If you are
far from a dealer, proceed as follows:
Remove the engine cover, and
1.
rinse the motor with fresh water to
remove salt water, sand, mud, etc.
If the motor 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 motor until it
has been repaired.
2. Drain the vapor separator as
described on page 141
3. Change the engine oil (see page
120
4. Remove the spark plugs (see page
122 ). Operate the starter to expel
water from the engine's cylinder.
5. Pour a teaspoon of engine oil into
each spark plug hole, then pull the
emergency starter rope several
times to lubricate the inside of the
cylinders.
Reinstall the spark plugs.
6. Install the engine cover and lock
the fixing lever securely (see page
52 ).
7. Attempt to start the engine.
If the engine fails to start, remove
the spark plugs, clean and dry the
electrodes, then reinstall the spark
plugs and attempt to start the
engine again.

MAINTENANCE
If there was water in the engine
crankcase, or the used engine oil
showed signs of water
contamination, then a second
engine oil change should be
performed after running the engine
for 1/2 hour.
If the engine starts, and no
mechanical damage is evident,
continue to run the engine for 1/2
hour or longer (be sure the water
level is at least 100 mm (4 in)
above the anticavitation plate).
8. As soon as possible, take the motor
to a Honda outboard motor dealer
for inspection and service.
