The major consideration in preparing your outboard 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 outboard for out of season storage or prolonged storage (two
months or longer)
- Protect the engine from physical damage. rust, corrosion and
dirt. Do not seal in a container or wrap tightly in plastic
or canvas as moisture could form and cause external and internal
rust and corrosion. Refer to the lubrication chart in your
owner operation and maintenance manual
- Lubricate swivel bracket, tilt tube and control linkage
- Remove spark plugs
- Apply Quicksilver Storage Seal into carburettors and spark plug
holes
- Connect spark plug wires, making sure each wire is connected to
the correct spark plug
- Clean exterior of motor, including all accessible powerhead
parts. Spray with Quicksilver Corrosion Guard
- Install cowling and apply Quicksilver Corrosion Guard to
all painted surfaces
- Remove propeller, lubricate propeller shaft spline and
reinstall
- When storing for winter, make sure water drain holes in gear
housing are open so water will drain out. Use a piece of wire
to clean out if necessary
- If a speedometer is installed in the boat disconnect the pickup
tube and allow it to drain, reconnect the tube. Trapped water
will freeze, cracking the gear housing and/or water pump
housing
- Drain and refill gear housing with Quickilver Gear Lube before
storage. Inspect gaskets under lubricant vent and fill
plugs. Replace damaged gaskets before reinstalling

WARNING:
As a safety precaution, when your boat is in
storage or transit remove positive (+) battery cable. This
eliminates the possibilty of accidental starting or cranking of the
engine and overheating and damage to engine from lack of water or
starter motor damage
CAUTION:
- NEVER start or operate your outboard (even
momentarily) without water circulating through all the cooling
water intake holes in the gearcase to prevent damage to the water
pump (running dry) or overheating of the
engine
- Oil injected engines - If after being in storage air
bubbles can be seen in the clear oil pump hose, see your authorised
dealer. Operate the outboard on pre-mixed fuel (50:1) until
the air is purged from the hose
FUEL SYSTEM:
Fuel containing alcohol (ethanol or methanol) can cause a
formation of acid during storage and can damage the fuel
system. If the fuel being used contains alcohol, it is
advisable to drain as much of the remaining fuel as possible from
the fuel tank, remote fuel line and engine fuel system.
Fill the fuel tank and engine fuel system with treated
(stabilized) fuel to help prevent formation of varnish and
gum. Proceed with the following instructions
- Portable Fuel Tank - Pour the required amount
of Fuel System Treatment and Stabilizer (follow instructions on
container) into the fuel tank. Tip fuel tank back and forth
the mix stabilizer with the fuel
- Permanently Installed Fuel Tank - Pour the
required amount of Fuel System Treatment and Stabilizer (follow
instructions on container) into a seperate container and mix with
approximately one litre of fuel. Pour this mixture into the
fuel tank
PROTECTING EXTERNAL OUTBOARD
COMPONENTS:
Touch up any paint nicks (see your dealer for touch up
paint)
Spray Quicksilver Corrosion Guard on external metal
surfaces(except corrosion control anodes)
