Off-Season Storage - Evinrude 100 Operator's Manual

OFF-SEASON STORAGE

You must protect against natural environmental
conditions that can be damaging to an outboard
motor. Temperature and humidity changes while
your outboard motor is not in use can cause corro-
sion of internal engine parts when they are not pro-
tected. Fuel remaining in your fuel tank and in the
engine will oxidize and weather which can result in
loss of octane and can cause gum deposits in the
fuel system. Your warranty does not cover engine
failure caused by these conditions. We strongly rec-
ommend that you have your DEALER prepare your
outboard for the off-season.
To do the off-season storage preparations yourself,
gather the supplies and perform the steps that fol-
low:
2+4 fuel conditioner
Triple-Guard grease
Ultra-HPF gearcase lubricant
Storage Fogging Oil spray can
Stabilize the engine's fuel supply with 2+4 fuel con-
ditioner during the last hours of operation to ensure
proper stabilization, following instructions on the
container for mixture. Be sure to run the engine
long enough for the treated fuel to reach the en-
gine.
WARNING
Prevent injury from moving engine compo-
nents. Before starting the engine:
Shift it to NEUTRAL.
Keep hands, clothes, hair clear of power-
head.
Remove the propeller if you use a flushing
device.
IMPORTANT: Provide a water supply to the engine
and start it — run it at idle only.
To run the engine on a flusher, refer to Flushing.
To avoid difficulty when restarting, never run the
engine with the fuel hose disconnected or run the
engine out of fuel.
Storage Fogging Oil — Following instructions
on the can, fog the engine by spraying through the
holes in the throttle plates in the throttle bodies.
Ignition, oil, and fuel systems — Check for mis-
placed leads and damaged or deteriorated parts.
Be sure starter solenoid terminal boot and all con-
nectors are in place.
Screws, bolts, nuts — Tighten
loose.
Propeller — Remove and examine. If damaged,
see your DEALER. Clean the propeller shaft and lu-
bricate it. Refer to Propeller.
Gearcase speedometer pickup, if equipped —
Disconnect the speedometer hose at the upper
connection. With air pressure no more than 25 psi
(167 kPa), blow all water from the gearcase speed-
ometer pickup system. Reconnect speedometer
pickup after all the water has been removed.
