While running my Yamaha 115 this weekend I noticed the rpms started to slowly drop off. I then looked behind me and saw blue/white smoke coming from my exhaust. I pulled the plugs 1 and 2 on the lake and they looked pretty good. I plulled plug number 3 tonight and it looked like it got in a fight with Mike Tyson. The plug was bend and had signs of impact. What could have dropped in the cylinder? Could the valve retainer or the valve seat have dropped?
