    Would be nice to know the LL in order to know the approach temp

    That said and without that means little, what's regulating your water flow? and have you checked your strainer?

    And that BTW anymore is illegal in most states as a replacement, so I would assume this system is older then dirt?

    More info needed

    As Chris said, you need to give your liquid refgt temp leaving the condenser to know if the condenser is efficient. As far as wastewater goes, most of those were designed around 105* condensing temp. Your split for 63* ecwt doesn't sound out of line, but we can't say what your condenser is doing from the info you imparted.
