Funky/fusion jazz with heavy base emphasis....

You could try: Music Revelation Ensemble very funky power fusion, PBD with Jaco on bass,Stuttgart Aria with Bireli Legrand on guitar and Jaco on bass, Essence (featuring Jaco) Last Flight.....These won't be easy to find but they might satisfy your jones for power funk jazz fusion, for a little while anyway.

I forgot to mention Stanley Clarke. Several choices are good but for power bass fusion the first one I like the best. Several Tony Williams Lifetime discs might work for you also as well as a couple of Tony Levin titles.
