be separated from the upper housing. The
studs can then be pressed out of the uppe~
housing and the hacksaw cut welded shut
and the housing returned to service. If the
studs cannot be pressed free, the upper
housing must be replaced.
SPECIAL NOTE
The upper housing has a bearing to ac-
commodate the pinion gear. This bearing is
comprised of 20 individual needles. TAKE
CARE not to lose any of the needles to the
bearing set.

retainer.

Remove the four screws in the bear-
ing head. This is the cap the propeller shaft
passes through. Notice how each screw has
an O-ring behind the head. These O-rings
MUST
be in place during installation to
maintain a water-tight unit.

With a small chisel and mallet, work
the cap free of the propeller shaft. The
chisel is to be worked on the cap, NOT in
the groove between the cap and the lower
housing. If the cap is damaged it may be
replaced without great expense, but damage
to the lower unit is BAD NEWS.
