STORAGE
56
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.
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.
