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.
IMPORTANT: NEVER paint the anode, its
fasteners, or its mounting surface. Painting
will reduce its corrosion protection.
WEEDY WATER
Weeds block water intakes and may cause
your outboard to overheat. Weeds on the pro-
peller create vibration and reduce boat speed.
When operating in weedy water, run at slow
speeds and in REVERSE frequently to clear
weeds from the propeller and water intakes.
Check the water pump indicator often.
If REVERSE operation does not clear away
weeds, SHUT OFF the engine. Remove
weeds from propeller area and water intakes
before operating at higher speed.
HIGH ALTITUDE
Your outboard's EMM will automatically com-
pensate for changes in altitude. However, if
you boat above 3000 ft. (900 m), you will ex-
perience a slight loss of power due to reduced
air density.
If your engine drops below the recommended
RPM operating range at full throttle, have your
Dealer select a lower pitch propeller.
If you return to sea level, have your Dealer in-
stall the original propeller and verify correct
RPM operating range.
FREEZING WEATHER
IMPORTANT: When operating in conditions
under 32°F (0°C), Evinrude/Johnson XD100
oil must be used.
During operation in freezing weather, keep
the gearcase submerged at all times.
Upon removing your outboard from the water,
leave it in a vertical position until its cooling
system is drained. Store the outboard verti-
cally.
If the outboard's gearcase is equipped with an
integral speedometer pickup, all water must
be cleared from the hose to prevent gearcase
damage. Refer to Storage on page 32.
WARNING
Water remaining in the gearcase, cool-
ing system or other components can
freeze, causing serious engine dam-
age.
SHALLOW WATER
Gearcase damage can occur if the gearcase
is allowed to drag on the waterway bottom.
Use caution when operating in shallow water.
IMPORTANT: Impact damage is NOT cov-
ered by the outboard warranty.
