Tell me about sea foam

[neveronsunday]

[#ff0000]Don't know much about boats-still on the straight up on the learning curve. I have a 70's vintage Mercury outboard that got pretty gummed up and someone mentioned sea foam. I have always liked Berryman's for automotive carb and injector clean up but am hesitant to use it on anything 2 stroke as it strips metal bare. Tell me about this sea foam, where to get it, how much is it, how do you use it, what to watch for, what not to do etc. or is there something better that you use? [/#ff0000]
