how do you change the fluid? it is not like other outboards. the "vent" hole is near the bottom on the starboard side and is very small. the "fill" hole is just below the cavitation plate on the port side. both holes are clearly marked. are you suppose to put this thing upside down to fill it? any info on this motor would be great...thanks.

please don't respond with instructions on how to change the lower unit fluid on a typical outboard.
