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 system (tank, hoses, fuel pump, and carburetor) 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.
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 reach the
carburetor.

Protecting External Outboard Components
4. Lubricate all outboard components listed in the Inspection and Maintenance
Schedule.
5. Touch up any paint nicks. See your dealer for touch-up paint.
6. Spray Quicksilver or Mercury Precision Lubricants Corrosion Guard on
external metal surfaces (except corrosion control anodes).

Protecting Internal Engine Components
7. Remove the spark plugs and inject a small amount of engine oil inside of each
cylinder.
8. Rotate the flywheel manually several times to distribute the oil in the cylinders.
Reinstall spark plugs.
9. Change the engine oil.

Positioning Outboard for Storage
11. To prevent problems which can be caused by oil entering the cylinders from
the sump, store the outboard only in one of the three positions shown below.
a. Upright
b. Tiller Side Down
c. Back Side Up
CAUTION
If outboard is on a boat and 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 out-
board.

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.
