Storage; Storage Preparation - Mercury 225 Manual

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.
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.
