Storage Preparation - Mercury 10 EFI FourStroke Installation, Operation & Maintenance 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.
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
the instructions on container) into the fuel tank. Tip the fuel tank back and
forth to mix the stabilizer with the fuel.
• Permanently installed fuel tank—Pour the required amount of gasoline
stabilizer (follow the instructions on container) into a separate container
and mix with approximately 1 Liter (1 US qt) of gasoline. Pour this mixture
into the fuel tank.
• Remove the fuel filter sight bowl and empty its contents into a suitable
container. Refer to Section 6 ‑ Fuel System for removal and installation
of the filter. Add 3 cc (1/2 tsp) of Quickstor Fuel Stabilizer into the fuel
filter sight bowl and install.
