SPECIAL OPERATING CONDITIONS
High Altitude
If you boat at altitudes above 3000 ft. (900 m), your
engine might benefit from a lower pitched propeller,
different carburetor calibration, or both. See your
Dealer.
Salt Water
Flush the engine internally after use in salt, pollut-
ed, or brackish water to help prevent mineral de-
posits from clogging cooling passages. Refer to IMPORTANT: To avoid permanent powerhead
Flushing.
damage, be sure that an engine modified for high
altitude operation is properly identified and returned
to original calibration and propeller size if operated
below 3000 ft. (900 m).
During use in salt or brackish water, additional an-
odic protection for the boat and outboard may be re-
quired.
During long periods of mooring, tilt the gearcase out
of the water — except in freezing temperatures.
Upon removal from salt water, leave it in a vertical
position until its cooling system has drained.
Shallow Water
IMPORTANT: Serious engine damage will occur if
the gearcase is allowed to drag on the waterway
bottom.
Weedy Water
Weeds block water intakes and cause your out-
board to overheat. Weeds on the propeller create
vibration and reduce boat speed.
Freezing Weather
DURING operation in freezing weather, keep the
gearcase submerged at all times.
Run at slow speeds and in REVERSE frequently to
clear weeds from the propeller and water intakes.
Check the water pump indicator often.
Upon removing your motor from the water, leave it
in a vertical position until its cooling system is
drained.
If REVERSE operation does not clear away weeds,
SHUT OFF the engine. Remove weeds from pro- IMPORTANT: Water that has leaked into the gear-
peller area and water intakes before operating at case, or remained in the cooling system or other

components can freeze, causing serious engine
damage.
Boat Bottom and Engine External Finish
Submerged Engine
The condition of your boat’s bottom affects perfor-
mance. A covering of marine growth reduces If your engine has been under water, have it ser-

running surface clean by wiping it dry after each use
and washing it occasionally.
viced immediately upon recovery. If immediate
service is unavailable, resubmerge it in fresh water
to avoid prolonged exposure to the atmosphere.
After operating your outboard, rinse it with fresh wa-
ter and wipe it dry. Apply Evinrude/Johnson Anti-
Corrosion Spray to any surface subject to corro-
sion, but avoid the anticorrosion anode(s).
After submersion, all boat and engine electrical, fu-
el, and oiling systems must be inspected for signs
of water intrusion. Your Dealer should perform this
service.
Periodically, wash the entire boat and outboard with
soapy water and apply a coat of automotive wax.
Leave the engine cover in place when washing the
outboard.
Under Tow
Should you require a tow from another boat:
•
•
•
Shift your engine to NEUTRAL;
Tilt its gearcase out of the water; and
Off-load all persons into another boat.
Keep towing speed slower than planing speed.
Auxiliary Engine
When your auxiliary engine is shut OFF, shift it to
NEUTRAL and keep its gearcase out of the water
by tilting it fully or raising the mounting bracket.
