season will be used in the next or the one
after. A small inexpensive pump can be be
purchased to move the lubricant from the
large container to the lower unit.
Position the drive unit approximately
vertical and without a list to either port or
starboard. Insert the lubricant tube into the
FILL/DRAILNI hole at the bottom plug hole,
and inject lubricant until the excess begins
to come out the VENT hole. Install the
VENT and
FILL
plugs with NEW gaskets.
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 com-
pletely full, install and tighten the vent
plug.
Check to be sure the vent and drain plug
gaskets are properly positioned to prevent
water from entering the housing.

ties.
