Storage Preparation - Mercury 200 Verado 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).
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.
IMPORTANT: This outboard is equipped with a closed fuel system
when the engine is not running. With this closed system, fuel within
the engine's fuel system, other than the fuel tank, will remain stable
during normal storage periods without the addition of fuel
treatment stabilizers.
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 Fuel System
Treatment and 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 Fuel System Treatment and Stabilizer (follow instructions
on container) into a separate container and mix with
approximately one liter (one quart) of gasoline. Pour this
mixture into fuel tank.
