I assume you're going to Newport for the aquarium (which, in my opinion, even better than Monterey Bay)?
It's only about an hour to Corvallis from Newport so if you leave Portland early you'll have plenty of time for a full day in Newport and then a quick jump over to Corvallis at the end of your day.
It would be about 3.5 hours of driving total (2.5 from Portland then another hour to Corvallis). Though that is assuming you take I-5 down to Corvallis and cut over to Newport. If you take 101 down the coast that would add 30 minutes to an hour depending on where you reached the coast (my preferred scenic route would be Portland to Tillamook, stop for cheese, drive south to Newport but that would be a 3-5 hour trip depending on your stops and whatnot).
