I can't find the upper unit drain plug -- is it a suck out the stop deal?
Also; I found the reference for the lower unit oil; but not the upper
unit.
What oil goes in there? approximate capacity?

Thanks

The drain is on the bottom and the upper vent is on top of the drive (if you
look at the top you will see the cover being held on with 4 bolts and a
screw dead center. This is the upper vent). You need to run the engine
until the drive is warm (in neutral). Open the bottom drain plug right side
bottom and then open the top. It will drain out 2qts of gear oil. I filled
mine with 2qts of Mercruiser synthetic gear oil. Be sure to get the pump.
Screw the pump into the bottle and the hose end into the bottom drain. Pump
in the 2qts then with the pump still connected screw in the top plug. This
will allow you to quickly remove the pump tube from the bottom and screw in
the plug. Remove the upper plug and check the level with the attached (to
plug) dipstick. Should be filled. The king cobra may use more oil but the
standard size uses two qts. As long as nothing milky or water comes out of
the drive you are done. Make sure the plugs are tight. It is a easy
process. Use the largest bladed screwdriver you have, if you strip the plug
you are in for a world of hurt. The drive is all one cavity so you are
changing all of the oil at one time. It seams like 2 qts will not be enough
to fill it but it is.....

Good luck,
