2005 Johnson 50 hp 2-Stroke Outboard Owners Manual

SPECIAL OPERATING CONDITIONS
Salt Water
Shallow Water
IMPORTANT: Serious engine damage will occur if
the gearcase is allowed to drag on the waterway
bottom.
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.
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.
Freezing Weather
DURING operation in freezing weather, keep the
gearcase submerged at all times.
Upon removing your motor from the water, leave it
in  a  vertical  position  until  its  cooling  system   is
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
Weeds  block  water  intakes  and  cause  your  out-
board to  overheat. Weeds on  the propeller create
vibration and reduce boat speed.
Run at slow speeds and in REVERSE frequently to
clear weeds  from the propeller and water intakes.
Check the water pump indicator often.
Submerged Engine
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.
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.
If REVERSE operation does not clear away weeds,
SHUT OFF the engine. Remove weeds from pro-
peller area and water intakes before operating at
higher speed.
Dual Engine Operation
Boat Bottom and Engine External Finish
When you are maneuvering at slow speed, be sure
both engines are running, even if one or both are in
NEUTRAL.
If it is necessary to return to harbor with one engine
not running, you should not attempt to operate the
boat above planing speed. Tilt the inoperative en-
gine high enough to keep its propeller out of the wa-
ter.
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.
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 corrosion,
but avoid the anticorrosion anode(s).
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.
High Altitude
Keep towing speed slower than planing speed.
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).
