Submerged Outboard Motor - Honda BF75D 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 dealer, proceed as follows:
1. Remove the engine cover, and rinse
the outboard motor with fresh
water to remove salt water, sand,
mud, etc.
2. Drain the vapor separator as
described on p.105.

3. Change the engine oil and oil filter
as described on p.82-84. 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.85).
Operate the starter to expel water
from the engine's cylinders.
5. Pour 1-2 teaspoons (5-10 cm
(p.107) 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.
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.
