STORAGE PREPARATION
The major consideration in preparing your outboard for storage is to protect it from
rust, corrosion, and damage caused by freezing of trapped water.
The following storage procedures should be followed to prepare your outboard for
out-of-season storage or prolonged storage (two months or longer).
CAUTION
Never start or run your outboard (even momentarily) without water circu-
lating through the cooling water intake in the gear case to prevent dam-
age to the water pump (running dry) or overheating of the engine.

Fuel system
IMPORTANT: Gasoline containing alcohol (ethanol or methanol) can cause
a formation of acid during storage and can damage the fuel system. If the
gasoline being used contains alcohol, it is advisable to drain as much of the
remaining gasoline as possible from the fuel tank, remote fuel line, and
engine fuel system.
Fill the fuel tank and engine fuel system with treated (stabilized) fuel to help prevent
formation of varnish and gum. Proceed with following instructions.
1. Portable Fuel Tank – Pour the required amount of Gasoline Stabilizer (follow
instructions on container) into fuel tank. Tip fuel tank back and forth to mix
stabilizer with the fuel.
2. Permanently Installed Fuel Tank – Pour the required amount of Gasoline
Stabilizer (follow instructions on container) into a separate container and mix
with approximately one quart (one liter) of gasoline. Pour this mixture into fuel
tank.
Carburetor Models
3. Place the outboard in water or connect flushing attachment for circulating
cooling water. Run the engine for ten minutes to allow treated fuel to fill the fuel
system.

Electronic Fuel Injection (EFI) Models
4. Remove the fuel filter sight bowl and empty contents in a suitable container.
Refer to Maintenance Section for removal and installation of filter. Add 3 cc (1/2
teaspoon) of gasoline stabilizer into the fuel filter sight bowl and reinstall.
5. Place the outboard in water or connect flushing attachment for circulating
cooling water. Run the engine for 15 minutes to allow treated fuel to fill the
engine fuel system.

Protecting External Outboard Components
1. Lubricate all outboard components listed in the Inspection and Maintenance
Schedule.
2. Touch up any paint nicks. See your dealer for touch-up paint.
3. Spray Quicksilver or Mercury Precision Lubricants Corrosion Guard on
external metal surfaces (except corrosion control anodes).
oid3
Protecting Internal Engine Components
1. Remove the spark plugs and inject a small amount of engine oil inside of each
cylinder.
2. Rotate the flywheel manually several times to distribute the oil in the cylinders.
Reinstall spark plugs.
3. Change the engine oil.

Gear Case
1. Drain and refill the gear case lubricant (refer to maintenance procedure).
oif3
Positioning Outboard for Storage
Store outboard in an upright (vertical) position to allow water to drain out of
outboard.
CAUTION
If outboard is stored tilted up in freezing temperature, trapped cooling
water or rain water that may have entered the propeller exhaust outlet in
the gear case could freeze and cause damage to the outboard.

Battery Storage
1. Follow the battery manufacturer’s instructions for storage and recharging.
2. Remove the battery from the boat and check water level. Recharge if
necessary.
3. Store the battery in a cool, dry place.
4. Periodically check the water level and recharge the battery during storage.
