I'm not convinced at all that a large number of outbound links, spread evenly through a site, have any bad effect.
One review site I have, which has almost zero inbound links, has on average three to four outbound links per page. Everything about the site has improved considerably over the last year.
The outbound links are mainly to sites with very low PR although their PR has remained at a low steady.
Admittedly, to date anyway, G hasn't found a way to compete with my site and maybe that is one reason for its success. But there are loads of sites out there with high numbers of outbound links which are flourishing. I would look for other reasons.
