quote Phil B:
A guy in to (formerly local) Mercury dealer parts department once said Permetex “High Tack” was as good as the Mercury and OMC gasket sealers
Probably is. But one of the original poster’s requirements was the messiness. Permatex is nasty to work with, hard to get off your hands, and shows like crazy on the finished motor, making it look like a shade tree has been working on it. A bit of rubbing alcohol cleans up after the OMC.
