$20,000+ > $500. Simple Math.
I amazed that that anyone would even consider this. To save a few hundred dollars, your going to risk several $10's of thousands? The chances for failure seem extremely high.
I had a similar situation occur to me this spring. Launched the boat. A thru-hull that didn't leak last year, was slowly weeping fluid (teaspoon every 5-minutes) at the flange/hull junction. Probably could have made it through the end of the season. Made the decision to have the yard guys yank the boat 2-hours after it was put in at a cost of $330. Decided since it was out to do all the old thru-hull at the same time. A couple hundred more in new thru-hulls and now everything is brand new and doesn't leak and won't until I probably sell the boat.
The cost of something going wrong with an in-water replace is way more than you think. Probably loss of boat, cost to raise the sunken boat, and god forbid if you release diesel/gas in to the water. Then you have a real mess on your hand.
If you liked my advice/response, give me some rep points. If you didn't......well what do you expect, it was free.
