There is probably a "part number", however, you already know your shaft size, all you need to do is measure the ID of the bearing strut and how long it is. You take these numbers to your favorite marine supply (not West Marine) and they will hook you up.
Replacing the bearing if you're not a menchanic could be a chore, as you must take your prop shaft out, (I know there are those who will disagree and there are fancy tools to get it out, I could not justify the rediculous cost of the tooling) get the old cutlass out, clean everything up, reinstall the new cutlass, reinstall and align the prop shaft. While your down there, cleaning up the shaft and the prop as well. I'd personally take the prop off and get it cleaned and balanced at a prop shop.
Be happy to walk you through it, pictures and all. Availability for the bearing I'd say your biggest concern.
