blackwater waste valve seal question
My blackwater valve is leaking around the shaft. Replacing it seems relatively straightforward but I've never done this before and have a question about the valve seals. The seals have an inner lip...

Thanks everyone for your help.
As I'd hoped, it was obvious which way to orient the seals when I took the old one out - as everyone here said, it's the way shown in my first photo -- with that inner lip facing inwards toward the valve.
This one was super easy and no mess at all, my blackwater tank has 2 valves, one near the tank, and this one by the drain outlet. I installed a blackwater tank flush system too, so after I flush out the tank well I'll swap out that other one which has become very hard to open. And I'll take @Horsedoc's advice and use my leveling blocks to angle the RV to keep residual liquid from dripping out.
The one piece of advice I didn't follow here was replacing the bolts with stainless steel - the current bolts weren't very rusty and were easy to get off. After tightening the new screws, I did coat the nut end of the threads with some grease, though I'm not sure that's really going to make a difference after a few years and I need to do this again unless I remember to do it regularly.
