Possible Missing Rear Vent On Lower End

[bigesox11]

Below are two pics of the lower end of my 2002 Mercury/Tracker 40ELPTO. It looks like there is a screw missing from my lower end vent. Can anyone confirm or deny? When I read an article about changing the gear case lubricant the photos showed a front vent, a rear vent and a fill hole. It looks like there is a plug missing from the rear vent. Or do some motors only have one vent and what would the hole pictured be for? Thanks.

Thanks for the reply. So this motor only has one vent then?
