Storage; Storage Preparation - Mercury 200 Sport-Jet Operation & Maintenance Manual

Storage Preparation

The major consideration in preparing your Mercury Jet Drive 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 Mercury
Jet Drive 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 Quickstor Fuel Stabilizer and Mercury Precision
Quickleen products to the fuel tank as described on their containers. 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
the instructions on the container) into the fuel tank. Tip the fuel tank back
and forth to mix the stabilizer with the fuel.
2. Permanently installed fuel tank ‑ Pour the required amount of gasoline
stabilizer (follow the instructions on the container) into a separate
container and mix it with approximately one liter (one quart) of gasoline.
Pour this mixture into the fuel tank.
3. Remove the water separating fuel filter from the engine. Empty the fuel
into a suitable container and discard the filter properly.
4. Premix the following in a container:
• 8.0 ml (0.27 oz) of Mercury Precision Quickleen
• 8.0 ml (0.27 oz) of Mercury Precision Quickstor
5. Pour this mixture into a new water separating fuel filter. Install the fuel
filter.
6. Fill the fuel system as follows:
a. Turn the ignition key switch to the "ON" position for three seconds,
and then back to the "OFF" position for five seconds.
b. Continue this procedure five times to allow the electric fuel pump to fill
the fuel system.
