I was having an overheat alarm. I removed both plates covering the exhaust to look for blockages. Turns out one of the t-stats was clogged, which was easy to fix. I cleaned up all the mating surfaces between the inner and outer exhaust manifold plates and got new gaskets. Am I supposed to use a gasket sealant since between these two plates is sea water? Or do they go on dry? I don’t want to put it back together until I know. If sealant, what brand and type should I use?
Thanks whoevers able to help. I sat on hold for an hour where I bought the gaskets, and they never called back! Hard to get good service these days.
