Default 90Hp Mercury Optimax NEED HELP

What's up guys,

I have a 2010 90 Hp Mercury Optimax 2 stroke outboard that is starting to give me trouble. This boat was given to me 2 years ago by my uncle, who had a mechanic maintain it over the last 8 years Recently on the past two runs we had the engine would bog down and lose a sufficient amount of power, out of nowhere the power would return but then it would be lost just as quick. We thought it was maybe it was some water in the fuel so we put in some starton in the but the problem persisted. The engine started fine, but never got enough power to come up on plane and the engine continued to stall out several times on the way in. We are guessing it is a fuel issue but we are not sure on where to start. I can't seem to find a water seperator on this boat,It's a 2010 Bayliner, Any help is appreciated, Thanks, Guys!
