...that is the question. Again.
I have read the Service Bulletin from Merc about the "new" graphite gaskets, circa 2001, that are to be installed dry. However, a search on this site and many others has turned up multiple posts from boat owners and marine mechanics who use Perfect Seal on those graphite gaskets. To me, it seems illogical to put a sealer on a soft surface like graphite, however, as I am about to undertake the procedure myself, I would like to ask again for clarification. I want a leak free installation, however, part of my confusion stems from not really being sure how the graphite gasket works anyway. Does the graphite bond to the metal (or more accurately, painted metal of the new parts)? Why does dry graphite create a better seal than all the myriad gasket materials and sealants that came before it?
In any case, I would like to have the conversation one last time before I undertake the reinstallation process, just to be sure.
Thanks in advance!
