Since I got no replys I went on and researched it myself, and this is what it said, 2 stroke oil if opened is good for two years if it's not opened and sealed its good for five years. 
Since I'm not 100 percent sure if this is correct,I am not going  to put and buy( a great deal too) the oil. I put to much money into my  boat to screw it up with putting expired oil into it.me personally it think it would be fine but I would feel comfortable using it. Maybe this info would be good for someone else,I don't want you to screw up your engine after all we are like family here.
