You say you have to disconnect the battery to stop the power drain? Take your multi-meter and set it on DCV with a range of 0-50 or there abouts. With the negative cable removed take a reading from the post to the cable. With everything off and your fuses removed like you said, there should be "0" current draw on the meter. If there is, you have a short somewhere not fused. Look for a chafed wire...if your battery drains in 3 hours I'd say it a major short like in your positive cable going to your starter.
I read allot about the ignition switch giving us Boxster owner fits, I wonder if that could be it?
You also said it's a new battery, because the old one drained also? Or did this just show up? If it just showed up the battery might have an internal short. I don't know what you paid for a Bosch battery but a Duralast Gold from Autozone is about $95 and it's warrantied.
P.S. Paul (above) is absolutly right, draining a battery in 3 hours will heat up at the point of the short.
