Here are a couple I found on Craigslist. Where are you located? I learned you can search a whole state. Craigslist search engine is not real sophisticated, so it seemed to get best results to just type in Wellcraft for your state and area of choice and sort through what you find. It appears there are a lot more V20's with outboards out there for sale.
