ANTI-CORROSION ANODES
Your outboard is equipped with one or more
anodes that protect it from galvanic corrosion.
Disintegration of the anode is normal and in-
dicates it is working. Check each anode peri-
odically. Replace anodes smaller than 2/3
their original size. See your Dealer for re-
placements.
Galvanic corrosion destroys underwater met-
al parts and can occur in fresh or salt water;
however, salt, brackish, and polluted waters
will accelerate corrosion.
Metal-based antifouling paint on the boat or
outboard and the use of improperly installed
shore power in the area of your moored boat
will also accelerate corrosion.
NEVER paint the anode, its
fasteners, or its mounting surface. Paint-
ing will reduce its corrosion protection.
DE-CARBONING PROCEDURE
This procedure is required every 100 hours or
annually for MFE 30 outboards operated us-
ing heavy fuels, including JP5, JP8, Jet A, or
kerosene.
If the outboard has been operated on an
emergency fuel, such as diesel, the de-car-
bon procedure must be performed immedi-
ately after return from the mission.
For maximum benefit, the outboard should be
run on unleaded gasoline during this proce-
dure if possible.
Outboard should be on the boat and in the
water. If outboard cannot be run in the water,
make sure to supply adequate cooling water.
DO NOT run outboard with-
out a water supply to the outboard’s cool-
ing system. Cooling system and/or
powerhead damage could occur.
1) Remove air silencer.
2) Set the fuel selector switch to the gasoline
position and run the outboard on gasoline
during the de-carboning procedure.
3) Start and run outboard long enough to
reach normal operating temperature.
4) Set engine speed to approximately 1500
RPM.

NOTICE
A
DANGER
DO NOT run the engine indoors or with-
out adequate ventilation or permit
exhaust fumes to accumulate in con-
fined areas. Engine exhaust contains
carbon monoxide which, if inhaled, can
cause serious brain damage or death.
A WARNING
To prevent injury from contact with
rotating propeller; remove the propeller
before de-carbon procedure.
