1-9 90-13645--2 495 GENERAL INFORMATION AND SPECIFICATIONS
10. Reinstall spark plugs, carburetors and fuel pump.
11. Attempt to start engine, using a fresh fuel source.
If engine starts, it should be run for at least one
hour to eliminate any water in engine.
12. If engine fails to start, determine cause (fuel, elec-
trical or mechanical). DO NOT allow engine to re-
main idle for more than 2 hours, as serious inter-
nal damage will occur. If unable to start engine in
this period, disassemble engine and clean all
parts and apply oil as soon as possible.
Out-of-Season Outboard Storage
WARNING
As a safety precaution, when boat is in storage,
remove positive (+) battery cable. This will
eliminate possibility of accidental starting of
engine and resultant overheating and damage to
engine from lack of water.
In preparing an outboard for out-of-season storage,
2 precautions must be considered: 1) The engine
must be protected from physical damage and 2) the
engine must be protected from rust, corrosion and
dirt.
1. Remove cowling from engine.
2. Place outboard in water or install Quicksilver
Flushing Attachment over water intake by follow-
ing instructions outlined in “Flushing Cooling Sys-
tem” (see “Table of Contents”).
3. Start engine and allow to warm up. Disconnect
fuel line. When engine starts to stall quickly spray
Quicksilver Storage Seal into each carburetor
throat. Continue to spray until engine dies from
lack of fuel.
4. Remove spark plugs and inject a 5 second spray
of Quicksilver Storage Seal around the inside of
each cylinder. Manually turn engine over several
times to distribute Storage Seal throughout cylin-
ders. Reinstall spark plugs.
5. If engine fuel filter appears to be contaminated, re-
move and replace. Refer to Section 3 “Fuel System
and Carburetion.”
6. Drain and refill lower unit with Quicksilver Gear
Lube, as explained in “Gear Housing Lubrication”
(see “Table of Contents”).
7. Clean outboard thoroughly, including all accessi-
ble powerhead parts, and spray with Corrosion
and Rust Preventive.
8. Refer to lubrication chart in this section (see
“Table of Contents”) and lubricate all lubrication
points.
9. Remove propeller. Apply Quicksilver Anti-Corrosion
Grease or 2-4-C w/Teflon to propeller shaft and re-
install propeller. Refer to “Propeller Installation” (see
“Table of Contents”).
10. If the water pickup is clogged, the speedometer
will be inoperative. Clean the pickup with a piece
of wire or blow out with compressed air. Before
blowing out with air, disconnect the tubing from
the speedometer.
11. To prevent freeze damage, drain the speedome-
ter system of water completely before storage.
Remove tubing from speedometer fitting and
blow thru the tubing to remove water.
12. Store battery as outlined in “Out-of-Season Bat-
tery Storage,” following.
13. For out-of-season storage information on
Autoblend units, refer to Section 8 in this service
manual.
IMPORTANT: When storing outboard for the win-
ter, be sure that all water drain holes in gear hous-
ing are open and free so that all water will drain
out. If a speedometer is installed in the boat, dis-
connect the pickup tube and allow it to drain. Re-
connect the tube after draining. Trapped water
may freeze and expand, thus cracking gear hous-
ing and/or water pump housing. Check and refill
gear housing with Quicksilver Gear Lube before
storage to protect against possible water leakage
into gear housing which is caused by loose lubri-
cant vent plug or loose grease fill plug. Inspect
gaskets under lubricant vent and fill plugs, re-
placing any damaged gaskets, before reinstalling
plugs.
