Questions & Answers about Я часами размышляю об этом, но безрезультатно.

Why is часами in the instrumental case, and how does it translate to "for hours"?

Using a time noun in the bare instrumental plural, like часами, expresses an extended or continuous duration of time. It conveys the feeling of doing something "for hours on end." You will see this pattern with other time words too, like годами (for years) or днями (for days).

We previously learned that "for [time]" usually takes the accusative case. Why can't we use the accusative here?

The bare accusative is used for a specific, measurable duration, like целый час (for a whole hour). The instrumental plural часами is used when the duration is vague but notably long and often repetitive. It emphasizes the extended, ongoing nature of the action rather than measuring it exactly.

What is the difference between using размышляю here instead of simply saying думаю?

While думаю generally means "I think," размышляю (from the imperfective verb размышлять) specifically means "to ponder," "to reflect," or "to mull over." It implies a deeper, more prolonged mental process, which pairs perfectly with the extended duration shown by часами.

Why is it об этом instead of о этом?

The preposition о (about) changes to об when the following word starts with a vowel sound (а, о, у, э, и). Since этом starts with э, we use об to make it easier to pronounce and to avoid an awkward pause between two vowels.
