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. Follow these storage procedures to prepare your outboard for out‑of‑season storage or prolonged
storage (two months or longer).

Fuel System Storage Preparation

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.
IMPORTANT: Gasoline containing alcohol (ethanol or methanol) can cause the 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 the instructions on the container) into the fuel
tank. Tip the fuel tank back and forth to mix the stabilizer with the fuel.
• Permanently installed fuel tank ‑ Pour the required amount of gasoline stabilizer (follow the instructions on the container)
into a separate container and mix with approximately 1 liter (1 U.S. quart) of gasoline. Pour this mixture into the fuel tank.
• Place the outboard in water or a water hose to the flush fitting for circulating cooling water. Run the engine for ten minutes
to fill the engine fuel system.
