I own an old (1988) Stingray 176 SBV. I've owned it for the last 3 years and have been very happy with it. Despite its age, its very mechanically sound. All gauges still work, motor (3.0L Mercruiser) has required nothing but PM since I purchased it. I did convert it to electronic ignition (Pertronix). I've never had to clean the carburetors, but I have replaced all the filters and added a fuel-water separator. Propped for speed, she'll run about 45 MPH. Currently I have it propped for water sports so its a little slower. She tracks well and planes fairly quickly. I have had to slowly replace all the seat wood, as the drainage (especially around the bow seats) is not the best and does tend to pool. If you work on your own engine, there is really good access to the entire engine space. It is a bit small, with just enough space for me, my wife, and two kids to be able to spend a day on the lake. We can carry a couple more people, but then it gets tight in terms of space. All in all, I would not hesitate to get another Stingray in the future. I also boat on Lake Lanier, and will admit that on busy summer days, its best to avoid busy areas as there doesn't feel like there is a ton of freeboard, and I have taken a wave or two over the bow on occasion.
