I have a 130 Yamaha 2 stroke with about 350 hours on it. I didnt use Ring Free for the first 250 hours, but have been using it religously this season. Should I shock treat the engine? When is "Shocking" it called for? Does 250 hours require shock doses of Ring Free? If I do shock it, is using the fuel/water seperator as a means of delivery a good idea? Too strong? The engine is running fine, and there are no problems but I would like to keep it that way. Any feedback is appreciated. Pat
