8-16 LOWER UNIT
FILLING THE LOWER UNIT
11-
FiU the lower unit with lubricant.
Insert the lubricant tube into the bottom
opening, and then fill the unit until lubricant
is visible at the vent hole.
Install the vent
plug. Remove the gear lubricant tube, and
install the drain/fill plug.
12- After the lower plug has been
installed, remove the vent plug again and
using a squirt-type oil can, add lubricant
through this vent hole. A squirt-type oil can
must be used to allow the trapped air in the
lower unit to escape at the same time the
final lubricant is added. Once the unit is
completely full, install and tighten the vent
plug.
PROPELLER INSTALLATION
FIRST, THESE GOOD WORDS
The propellers used on the outboards
covered in this section have a removable
clutch ring and a clutch hub, and bushing.
Under normal conditions, these items are
NOT removed from the propeller. However,
if they have been removed for any number
of reasons, they should be coated with OMC
Type "A" lubricant prior to installation. The
bushing is installed first, then the clutch
hub, and finally the clutch ring.
13- Install the shear pin. Apply a light
coating of anti-corrosive lubricant onto the
propeller shaft. Slide the propeller onto the
shaft, then the washer, and finally the pro-
peller nut, with the flange on the nut TO-
WARDS the propeller. Tighten the nut
securely. Install a cotter pin to prevent the
nut from backing out. Slip the rubber cap
over the propeller nut.
14- Perform a functional check of
the completed work by mounting the
engine in a test tank, in a body of
water, or with a flush attachment
connected to the lower unit. If the
flush attachment is used, NEVER operate
the engine above an idle speed, because
the no-load condition on the propeller would
allow the engine to RUNAWAY resulting in
ser ious damage or destruction of the engine.
