STORAGE

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 operate your outboard (even momentarily) without
water circulating through all the cooling water intake holes in the
gearcase to prevent damage 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.
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.
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.
Place the outboard in water for circulating cooling water. Run
the engine for ten minutes to fill the engine fuel system.
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.
