Just bought this motor. Seems to be in good shape, and runs good. Want to check the lube in lower unit, but can't find the fill or drain plugs. Am I blind?

The drain is a large plug toward the front of the bullet on the starboard side. The vent is a small plug just above the antiventilation plate, also on the starboard side.
