If you have to remove stuff to access it, you have to remove stuff. It is not unusual in a 29' twin inboard boat to have remove a bunch of stuff to improve access.

However, my advice would be to make sure you have properly identified the problem before trying to fix it. Most Tiaras shipped with externally regulated alternators and what looks like an alternator problem may actually be the regulator, which would be mounted remotely. The only thing worse than having to disassemble stuff to remove a broken alternator would be to do the same and later realize it was even broken.
