PREDELIVERY PREPARATION AND STORAGE
6. Operate the engine sufficiently to bring it up to normal operating temperature and allow fuel
with Mercury/Quicksilver Gasoline Stabilizer to circulate through the fuel system. Shut off the
engine.
7. Change the oil and oil filter.
8. Prepare the engine and fuel system for storage. See Engine and Fuel System
Preparation.
9. Drain the engine seawater cooling system. See Draining the Seawater System.
Water trapped in the seawater section of the cooling system can cause corrosion or freeze
damage. Drain the seawater section of the cooling system immediately after operation or before
any length of storage in cold weather. If the boat is in the water, keep the seacock closed until
restarting the engine to prevent water from flowing back into the cooling system. If the boat is
not fitted with a seacock, leave the water inlet hose disconnected and plugged.
10. For additional assurance against freezing and rust, after draining, fill the seawater cooling
system with propylene glycol mixed to the manufacturer's recommendation to protect engine
to the lowest temperature to which it will be exposed during freezing temperatures or extended
storage.
11. Store the battery according to the manufacturer's instructions.

ENGINE AND FUEL SYSTEM PREPARATION

Fuel is flammable and explosive. Ensure the key switch is off and the lanyard is positioned so
that the engine cannot start. Do not smoke or allow sources of spark or open flame in the area
while servicing. Keep the work area well ventilated and avoid prolonged exposure to vapors.
Always check for leaks before attempting to start the engine and wipe up any spilled fuel
immediately.
Fuel vapors trapped in the engine compartment may be an irritant, cause difficulty breathing, or
may ignite resulting in a fire or explosion. Always ventilate the engine compartment before
servicing the power package.
Running out of fuel can damage catalyst components. Do not allow the fuel tanks to become
empty during operation.
