Water Separator Indicator; Submerged Outboard Motor - Honda BF200A Owner's Manual

TAKING CARE OF UNEXPECTED PROBLEMS
SUBMERGED OUTBOARD
MOTOR
A submerged outboard motor must be
serviced immediately after it is
recovered from the water in order to
minimize corrosion.
If there is a Honda Marine dealership
nearby, take the outboard motor to the
dealer immediately. If you are far
from a dealership, proceed as
follows:
1. Remove the engine cover (p. 61),
and rinse the outboard motor with
fresh water to remove salt water,
sand, mud, etc.
2. Drain the vapor separator as
described on p. 84 – 85.

3. Change the engine oil and oil filter
as described on p. 63 – 65. 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. 67).
Operate the starter to expel water
from the engine's cylinder.
5. Put a teaspoon 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.
