off season storage
Your war~an~y ~oes not cover engine failures caused by neglect or abnormal use.
Th~refore, It IS Important that you protect y our engine with a well planned quality
mamte~ance progra _ m. The off season storage of your Evinrude is an important con-
Siderah_on towa_ rd ~ts long and trouble free operation. Temperature and humidity
fluct~atwns while m storage can produce rust on piston rings, cylinder walls, and
beanng surfaces that are not properly protected . While a rusted engine may be
started, the extreme wear caused under these conditions can lead to an early ove _
haul. r
Many
d~alers throughout the country offer pre-storage care at a nominal cost.
However, If you desire to prepare y our own engine, proceed as follows:
Never run a motor out of water .
1. Run the motor until warm in fresh
water.
2. With engine running at fast idle, in-
ject rust preventative oil into the
carburetor until engine stops. For a
clean engine and rust proof motor we
recommend use of OMC "ENGINE
CLEANER" and "RUST PREVENTA-
TIVE" . These may be obtained at
your authorized Dealer.
3. Remove motor from tank , place up-
right, set speed control at "Stop", and
pull starter through slowly to drain
any water from water pump. Be care-
ful not to start engine.
4.
Drain and refill gearcase. (See Lu-
brication Chart.)
5. Remove propeller. Clean and lubri-
cate shaft.

REMOVAL FROM STORAGE FOR USE
When removing y our motor from stor -
age, it is a good policy to clean your
motor and make the following prepara-
tions:
1. Remove spark plugs. Clean, regap
and re-install to proper tightness
(17-1/ 2 to 20-1 / 2 ft. lbs.).
2. Give motor thorough visual check for
loose screws or damaged and worn
parts.
3. Pull starter through sl owly to make
sure motor turns freely .

SUBMERGED MOTORS
There are two situations to consider when dealing with a submerged motor. Did
it go overboard while running or stopped ? If a motor is lost overboard while run-
ning, it should always be disassembled before any attempt is made to start it. Often
internal parts are sprung and running under these conditions can result in permanent
damage.
A motor lost overboard in salt water for a period longer than two hours sho u ld
always be disassembled and cleaned before starting is attempted. Some materials
used in modern engines are subject to very rap id corrosion in the presence of salt
water and should be inspected to determine if replacements are required.
Your dealer should always be consulted in these cases as he is best equipped to
inspect for and repair internal damage.
A motor lost overboard in fresh water can usually be safely started if recovered
within twelve hours providing no sand or silt is present. Remove the spa rk plug,
the carburetor orifice screw, and drain all fuel lines and tank. Pull the starter
until all water present has been expelled. Reassemble and start.
If sand has entered the engine, no attempt at starting should be made . Return
it to y our deal er for disassembly and cleaning .
If it is impossible to have the engine serviced immediately after it has been re-
triev ed after extended submersion, it is advisable to submerge the powerhead in
clean fresh water to prevent oxidation until it can be serviced.
