First thing to check is your idle timing. A too retarded timing will cause that on your motor. If that doesn't cure it then Here's what I would do. First, tear down the carbs and give them a good soaking and thoruogh cleaning of all jets/orifices and passageways. Rebuild them with new kits. Then do a link & sync as per a factory manual.

My 2000 90hp did exactly that. A compression check showed a bad cylinder. It was 75psi versus 135 everywhere else.
