1989 Nissan with mercury classic fifty - 15' 3" Boat would not plain at first ran steady with throttle full forward, shut it off started again and it took off plaining fine several times stopped to a idel and went to take off and it's not plaining. Took bottom carb bowl off and it had a yellow film on the inside of the bowl. Question being: Is this the carbs that need to be rebuilt?

Sounds like the carbs need to be cleaned. If it runs good sometimes, then bogs down, chances are that it's a carb problem. That's where I would start.
