Blew the workhead in the Mercury Optimax 200 today.... Took the number 6 plug out and it was clearly covered in pieces of metal from inside the engine. Only 208 hours and wasn't ran hard at all. I guess they don't make things like the used to anymore. Needless to say their were a few choice words expressed and its probably a good thing no one else was around when it happened. 2nd motor in 3 years...
