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).
Without sufficient cooling water, the engine, the water pump, and other
components will overheat and suffer damage. Provide a sufficient supply of
water to the water inlets during operation.
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 the following instructions.
• Portable fuel tank ‑ Pour the required amount of gasoline stabilizer (follow
instructions on container) into the fuel tank. Tip fuel tank back and forth to
mix stabilizer with the fuel.
• Permanently installed fuel tank ‑ Pour the required amount of gasoline
stabilizer (follow instructions on container) into a separate container and
mix with approximately one liter (one quart) of gasoline. Pour this mixture
into the fuel tank.
• Remove the fuel filter sight bowl and empty contents in a suitable
container. Refer to Maintenance ‑ Fuel System for removal and
installation of filter. Add 3 cc (1/2 tsp.) of gasoline stabilizer into the fuel
filter sight bowl and install.
• Place the outboard in water or connect flushing attachment for circulating
cooling water. Run the engine at idle RPM for 15 minutes to fill the engine
fuel system with stabilized fuel.

Protecting External Outboard Components

• Lubricate all outboard components listed in Maintenance ‑ Inspection
and Maintenance Schedule.
• Touch up any paint nicks. See your dealer for touch‑up paint.
• Spray Quicksilver or Mercury Precision Lubricants Corrosion Guard on
external metal surfaces (except corrosion control anodes).
