NOTICE
This procedure covers only the power package por-
tion of your boat. Consult your boat owner’s manual
or boat manufacturer for specific boat winterizing
instructions.
GENERAL PREPARATION
Before beginning you will need the following supplies:
• Sta-Bil Gasoline Stabilizer
• 6 quarts of Appropriate Engine Oil
(10 quarts for 8.1 Liter)
• 501001 Oil Filter for 5.7 Liter Carbureted and EFI
Engines
• 501018 Oil Filter for 6.0 and 6.2 Liter Engines
• 4-6 ounces of Marine Fogging Oil
• 1 can Corrosion Protectant and Lubricant
• Transmission Oil (As Required)
• Multipurpose Grease
• Short Piece of Stiff Wire (Coat hanger wire)
• Pipe Thread Sealant
• Anti-Freeze Tester suitable for Propylene Glycol
(Fresh Water Cooled Engines Only)
• Propylene Glycol Anti Freeze (As required for Fresh
Water Cooled Engines Only)
Fuel System Treatment
1. If the boat is to be placed in storage with fuel in the
tank(s) that does not contain alcohol, fill the fuel
tank(s) with fresh fuel and a sufficient amount of
Marine Formula Sta-Bil gasoline stabilizer to treat the
entire tank. Follow instructions on the container.
2. Start the engine and operate at Idle RPM until the
engine reaches normal operating temperature. (If
using a hose and adapter, adjust the faucet to avoid
over-cooling the engine at low RPM.) Run the engine
for at least 15 minutes to ensure that the fuel stabiliz-
er enters the engine’s fuel system.
Running the engine with the flame arrestor
removed increases the possibility of fire or
explosion if engine backfire occurs and
gasoline fumes are present. If the engine is
operated without the flame arrestor secured,
extreme care must be taken to ensure that
the engine compartment is well ventilated
and that no fuel leaks are present.
