Checking Lubricant Level and Filling

Gear Case

Never add lubricant to gear housing
IMPORTANT:
without first removing VENT plug, as trapped air
will prevent housing from being filled. Fill gear
housing only when outboard is in operating posi-
tion.
NOTE: Refer to "Specifications," for gear housing
lubricant capacity.
1. With outboard in operating position, insert lubri-
cant tube into fill hole.
2. Fill gear housing until excess lubricant flows from
VENT hole.

b - Vent Hole
3. Install VENT plug and washer.
4. Install FILL plug and washer.

Storage Preparations

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).
Never start or run your outboard (even momen-
tarily) without water circulating through all the
cooling water intake holes in the gear case to pre-
vent damage to the water pump (running dry) or
overheating of the engine.

Protecting External Outboard
Components
1. Lubricate all outboard components listed in the
Inspection and Maintenance Schedule.
2. Touch up any paint nicks. See your dealer for
touch-up paint.

3. Spray Quicksilver Corrosion Guard on engine ex-
terior, electrical components, and other metal
surfaces (except corrosion control anodes).
Protecting Internal Engine
Components
NOTE: Before performing the following steps, make
sure the fuel system has been prepared for storage.
Refer to Fuel System.
1. Place the outboard in water or connect flushing
attachment for circulating cooling water. Start the
engine and let it run in neutral to warm up.
2. With engine running at fast idle, stop the fuel flow
by disconnecting the remote fuel line. When en-
gine begins to stall, quickly spray Quicksilver
Storage Seal into carburetor until engine stops
from lack of fuel.
3. Remove the spark plugs and inject a five second
spray of Quicksilver Storage Seal around the in-
side of each cylinder.
4. Rotate the flywheel manually several times to
distribute the storage seal in the cylinders. Rein-
stall spark plugs.
