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).
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.
The most effective method for storage preparation is to add the
recommended amount of Mercury Precision Fuel Stabilizer and Mercury
Precision Quickleen products as described on their containers to the fuel
tank before the last operation of the boat. Adding Fuel Stabilizer will help
prevent the formation of varnish and gum in the gasoline. The Mercury
Precision Quickleen product will help clean and lubricate the fuel injectors.
1. 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.
2. 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.
3. Pull the drain hose off the right side fitting. Hold the open end of the
hose over a container. Loosen drain screw and drain the fuel filter
chamber.
