I did all my own car repair in high school because i couldn't afford a mechanic so I do have some skills. Now i pay to have most car work done because i just don't want to do it myself. BUT, i did my own winterization last year. I would highly recommend it as you learn a lot about your boat in the process. When something happens to you on the water you will be much better prepared and relaxed to deal with it.
