Are there any places I can cheat and use permatex liquid gasket on the out drive? I know it works for sealing the ends of intake manifolds on the motor so u would think it would be strong enough.
For the outdrive, I would guess the Sierra would have all the gaskets you would need to do a complete rebuild if you wanted. They carry gaskets for the older Stringer outdrives as well so I would think they would have them for cobras too.
