SPECIAL OPERATING CONDITIONS
Salt Water
Shallow Water
IMPORTANT: Serious engine damage will occur if
the gearcase is allowed to drag on the waterway
bottom. Refer to Shallow-water drive.
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
Flushing.
Freezing Weather
DURING operation in freezing weather, keep the
gearcase submerged at all times.
During use in salt or brackish water, additional an-
odic protection for the boat and outboard may be re-
quired.
Upon removing your motor from the water, leave it
in a vertical position until its cooling system is
drained.
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.
IMPORTANT: Water that has leaked into the gear-
case, or remained in the cooling system or other
components can freeze, causing serious engine
damage.
Weedy Water
Submerged Engine
Weeds block water intakes and cause your out-
board to overheat. Weeds on the propeller create
vibration and reduce boat speed.
If your engine has been under water, have it ser-
viced immediately upon recovery. If immediate
service is unavailable, resubmerge it in fresh water
to avoid prolonged exposure to the atmosphere.
Run at slow speeds. Stop and raise motor frequent-
ly to clear weeds from the propeller and water in-
takes. Check the water pump indicator often.
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.
Boat Bottom and Engine External Finish
The condition of your boat’s bottom affects perfor-
mance. A covering of marine growth reduces
speed. For maximum performance, keep the boat’s
running surface clean by wiping it dry after each use
and washing it occasionally.
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.
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).
Keep towing speed slower than planing speed.
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.
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.
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.
IMPORTANT: To avoid permanent powerhead
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).
