"on the opposite side of the drain/fill on the lower unit are 2 machine made holes. Oil/grease has dripped out of these holes, but engine runs fine and after loosening the fill screw, there seems to be adequate oil in the lower unit. These holes are not addressed in the manual.

This is normal and nothing to worry about..."
