Steering link rod pivot points ‑ Lubricate the pivot points.
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 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 1 liter (1 U.S. quart) of gasoline. Pour this mixture into fuel tank.
•
Place the outboard in water or connect flushing attachment for circulating cooling water. Run the engine for ten minutes to
fill the engine fuel system.

Protecting Internal Engine Components
•
Remove the spark plugs and add approximately 30 ml (1 oz.) of engine oil or inject a five second spray of storage seal
inside of each cylinder.
•
Rotate the flywheel manually several times to distribute the oil in the cylinders. Install spark plugs.
•
Change the engine oil.
Gearcase
•
Drain and refill the gearcase lubricant (refer to Gearcase Lubrication).
