Greasing lower unit on old ob with no fill plug available

" I need to know how to grease

" I need to know how to grease the lower unit on an old Clinton outboard (5 horse). It has no plug screws, only 4 mounting bolts which hold the bottom cap with the keel to bottom 1/2 of the chunk. Is there any way to get grease to the foot of the Clinton engine short of breaking the seal on the bottom of the foot? "

" On models that have no fill

" On models that have no fill and vent plugs, --Invert the unit ,remove propeller and gearcase coverand fill gear cavity with lubricant. On the model K-201 gear oil is installed or drained through the screw hole in the retainer which is just behind the prop. If you can give me the model number I might be able to give you more information on your motor. I have had a couple clintons, they were great engines not quick but had a lot of torque. "
