Attached is a list of issues with the Honda 200/225. Note that it is two pages, so print it and put the pages side by side.
One thing you need to check right away is the third item on the list - the intermediate drive shaft bearing. Drop the lower unit like you are going to change the water pump and look up the drive shaft and check that the mid-shaft bearing is in good shape. If it fails, it will eat a hole in the front of your lower cowling.
If you are not familiar with these engines, I highly recommend that you invest in the official Helm Shop manual. Don't waste your time on the after-market manuals - too many errors and omissions. If you order online, make sure it is the early manual for your engine.
The Honda BF200A, BF225A Marine Outboard Shop Manual covers service and repair procedures for the BF200A and BF225A A2 through K0 marine engines. See FAQs for assistance in locating your frame serial number.

Also, here is a link to a manual that you can get online. It is about 95+% correct for your engine. It is a PDF file, so you can save it to your computer.
I'm also attaching a very detailed maintenance schedule just to show you what you need to check and replace at different time intervals.
