Thru Hull (transom) repair ?

[newellchunker]

While I've been messing around I found that a thru hull fitting was piss poorly installed on my Sceptre. There is some rot around the thru hull and the areas immediate to it, the rest of the area out another half inch to inch are good....how is the best way to fix this....the thru hull was an inch and a half diameter. I'm planning on redoing the transom and installing a bracket in a couple of years and don't want to get TOO involved at this time.
