2003's with only 30 hours is going to have significant issues. These engines do not take kindly to long set ups. The bearings are all likely dry, so you may want to get some good batteries, pull the plugs, pull the kill switch, and crank them for a while to get oil circulating. Someone else may have a better solution for getting oil to the bearings. When set up and let dry like that, you are also likely to have an issue with the trust bearing. When that fails, the engine is toast.
Attached is a list of issues with the 225. Note that there are two pages.

The exhaust tubes should be replaced with the upgraded ones per Honda SB # 56. That SB is too big to upload on this site, so send an e-mail to me requesting a copy of SB #56.

When you change the water pump, closely inspect the mid-shaft bushing and lubricate it. And every time you change an impeller, inspect for wear, or wobble. If that bushing fails, it can eat a hole right in the front of the lower cowling.
Pull all electrical connectors and check for corrosion - especially those three big ones plugging into the ECU.
Exercise the tilt/trim and look for leaks around the hydraulic cylinders. The seals have likely dried out. Same for hydraulic steering ram.
That's top of mind. Hopefully others will kick in with a reply.
