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).
NOTICE
Failure to provide sufficient cooling water will damage the water pump and cause the engine to
overheat. Provide a sufficient supply of water at 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.
IMPORTANT: This outboard is equipped with a closed fuel system when the engine is not running. With
this closed system, fuel within the engine's fuel system, other than the fuel tank, will remain stable during
normal storage periods without the addition of fuel treatment stabilizers.
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 Fuel System Treatment and 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 Fuel System Treatment and
Stabilizer (follow instructions on container) into a separate container and mix with approximately
one liter (one quart) of gasoline. Pour this mixture into fuel tank.
