Hot and Hi - thanks!
Sadly, I can't - this is what my POH has a standard OGE hover ceiling vs gross weight chart (I tried to embed it here but the site doesn't let me add images until I have 10+ posts :-).
I don't know how to get a MAP for OGE at sea level, standard day, at 2100 lbs, from that chart, for example. I know I can OGE at 10,000ft at 2100lbs on a standard day at full throttle (which would be ~19" at that altitude I believe), but I don't know how to convert that to sea level. Perhaps I am missing something...
Thanks!
