Section 6 - Storage
90-899883179 OCTOBER 2007 Page 87
NOTICE
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.
9. Ensure that the sterndrive vent holes and water drain holes and passages are
unobstructed and open (refer to Draining Instructions).
10. For additional assurance against freezing and rust, after draining, fill the 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.
NOTICE
The universal joint bellows may develop a set when stored in a raised or up position,
causing the bellows to fail when returned to service and allowing water to enter the boat.
Store the sterndrive in the full down position.
11. Store boat with drive unit in full down/in position.
12. Store the battery according to the manufacturer's instructions.
ENGINE AND FUEL SYSTEM PREPARATION
!
WARNING
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.
!
WARNING
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.
1. Prepare carbureted fuel system for extended storage as follows:
a. Start engine.
b. Provide cooling water to the engine as done in the previous step.
c. Remove flame arrestor assembly.
d. Close the fuel shut off valve, if equipped. Disconnect and plug the fuel inlet fitting
if not equipped with a fuel shut off valve.
e. While operating engine at fast idle (1300 RPM), fog internal surfaces of induction
system and combustion changers by spraying approximately 227 g (8 oz.) of
Mercury/Quicksilver Storage Seal or SAE 20W engine oil into carburetor bores.
f. Spray the remaining 57 g (2 oz.) of Storage Seal (or oil) rapidly into carburetor,
just as the engine begins to stall, due to lack of fuel. Allow engine to stop.
