No - sorry, I was unclear. I removed many of the outbound links from my page - I have no control over any of my backlinks at all because I didn't build them.*
I understood that you were referring to outbound links from your page. And I think they probably were helping your rankings. For years I've made it a practice, where feasible, to add a few outbound links to authoritive sites at the bottom of my articles, and I'm convinced that it does help rankings.
As for a maximum limit, such as 50, on the number of outbound links, I strongly doubt that "too many" can hurt you, as long as they as they don't point to spammy sites.
