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).
Failure to provide sufficient cooling water will damage the water
pump and cause the engine to overheat. Provide a sufficient
supply of water at 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 of storage preparation is to add the
recommended amount of Mercury Precision Fuel Stabilizer and
Mercury Precision Quickleen products as described on the
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 and Quickleen (follow instructions on containers)
into fuel tank. Tip fuel tank back and forth to mix stabilizer and
Quickleen with the fuel.
2. Permanently Installed Fuel Tank ‑ Pour the required amount
of gasoline stabilizer and Quickleen (follow instructions on
containers) into a separate container and mix with
approximately 1 liter (1 quart) 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.
