TO REPLACE THE CARRIER SEAL:
1. Clean any accumulated dirt and scale from the
exposed shaft. MAKE SURE THERE ARE NO
SHARP EDGES OR BURRS ON THE
SHAFT.
2. Separate the two halves of the Carrier Seal Kit
housing by removing the screws. If there are
two lip seals in the carrier kit, move the forward
most one forward on the shaft until out of the
way.
3. Remove the retaining ring from the Strong
Seal™ using a small screwdriver (for a
spiral ring) or snap-ring pliers (for a snap
ring). Work the retaining ring around the
new lip seal and move the ring forward out
of the way.
4. Reassemble the empty Carrier Seal Kit
housing onto the shaft just forward of the
new lip seal with the small diameter facing
aft. Leave the screws loose enough that
the housing can move along the shaft. The
Carrier Seal Kit housing is now ready to
be used as a lip seal installation tool.
5. Push needle-nose pliers or a hook into the
exposed body of the lip seal and pull it out of
the Strong Seal
housing. Cut the old seal off
the shaft with wire cutters. BE CAREFUL NOT
TO SCRATCH THE SHAFT.
6. Inspect and clean the inside of the Strong
Seal™ housing and the newly exposed area
of the shaft that was under the old lip seal.
7. Push the new lip seal and installation tool aft
until the lip seal contacts the Strong Seal™
housing. Using a rubber mallet, tap the face
of the installation tool until the lip seal is
seated within the Strong Seal™ housing. You
will know the lip seal is fully seated when the
retaining ring groove is exposed.
8. Remove the Carrier Seal Kit housing from
the shaft. Reinstall the retaining ring into its
groove in the Strong Seal™ housing.
9. If the Carrier Seal Kit came with two lip seals,
position the remaining lip seal back onto a
convenient location on the shaft at least 2"
forward of the Strong Seal™. Reassembly the
Carrier Seal Kit housing around the lip seal with
the smaller diameter facing forward. Tighten the
screws and make sure the assembly is firmly
secured on the shaft.
NOTE: As the Carrier Seal Kit is turning with the
shaft and the Strong Seal™ is not, it is important
that the two do not touch.
D. STRUT
The strut is the bronze casting fastened to the
bottom of the hull to support and form a bearing for
the propeller shaft. A replaceable rubber bearing is
inserted to minimize wear and protect the shaft
where it passes through the strut hub. During lay
up periods, squirt castor oil into this bearing to keep
it from freezing to the shaft. Never use machine
oil or grease on rubber bearing. Periodically check
all strut fastenings to assure that they are secure.
