Just an update on the intermediate shaft bearing. I just had a complete service done at 625 hours by The Honda Centre in Vancouver Canada. I asked them to replace the intermediate bearing on the drive shaft as I had heard of issues with it here. After he pulled the lower end off he showed it to me. It was in great shape grease still intact, no corrosion at all,anywhere. He said that in servicing the 225 since they were first introduced, they have never seen one fail. He said not to bother, and we left it. We will see, they sold me the engine and have a great reputation, the mechanic seemed to know the engine inside out,and I have confidence in his opinion. Definately a good idea to check it though for sure. I flush the engine after every use and he said it shows. There are no signs of corrosion anywhere and inside the engine looks the same as when it was new. Corrosion protectant and greas ehelp a great deal.
