MAINTENANCE
Maintenance, replacement, or repair of the
OFF-SEASON STORAGE
emission control devices and systems may be
performed by any marine SI (spark ignition) en-
gine repair establishments or individual.
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.
WARNING
Only perform service procedures which are
detailed in this Operator’s Guide. Attempt-
ing to perform maintenance or repair on
your outboard if you are not familiar with
the correct service and safety procedures
could cause injury or death.
To do the off-season storage preparations yourself,
gather the supplies and perform the following steps.
2+4 fuel conditioner
Triple-Guard® grease
Ultra-HPF gearcase lubricant
Storage Fogging Oil spray can
Tampering with the carburetor to change horse-
power or modify emission levels beyond factory
settings or specifications will void the product war-
ranty.
10-HOUR INSPECTION
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.
After 10 hours of operation, your new engine will be
broken in and its mechanical parts will have seated.
At that time, all systems should be checked and any
adjustments needed should be made.
Your DEALER will perform this 10-Hour Inspection
at your request and expense (based on local rates),
according to what your engine needs — refer to En-
gine Maintenance and Inspection Schedule, 10-
hour Inspection for a partial list.
Follow consistent preventive maintenance by hav-
ing your DEALER check and service your engine
once a year or after each 100 hours of operation,
whichever comes first.
WARNING
Prevent injury from moving engine compo-
nents. Before starting the engine:
Shift it to NEUTRAL.
Keep hands, clothes, and hair clear of pow-
erhead.
Remove the propeller if you use a flushing
device.
IMPORTANT: Provide water supply to the engine
and start it. Run the engine 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.
