    The 1989 Factory OMC 9.9/10/14/15/20/25/28/30/35 Service Manual has a photo in the carb section of the spray Gumout in use by the person cleaning the carb.The manual didn’t refer to Gumout specifically. It read "never clean a carb by submerging or soaking it in a hot tank or carburetor cleaner. Do not expose plastic or rubber parts to any carb cleaner" and "clean parts with a mild aerosol solvent". In the past i used the Engine Tuner on 3 different carbs,with great results. I wouldn’t use either cleaner on the plastic carb top or float bowl.
    EDIT for Correct info
