Oh, please don't get discouraged. GA Boater is just trying to help you learn the posting protocol for the site.
I don't believe your boat looks that bad at all. But then again, I always see the finished product. I own a 33 year old cruiser that I cannot part with and just keep working on.
Getting the paint off is a simple, if not painstaking, chore. Simply start with paint dissolving gel and get to scraping. Be careful scraping. If you use steel scrapers you can puncture the aluminum.
Once the paint is off, check the transom really good. Make sure it is solid and can support a motor. Check the hull for cracks, cuts, leaks. Aluminum is easily welded and repaired and you can find someone locally to do that.
