all my babbling, I forgot to add that its considered a lubricant/sealer.

Im using the Mercruiser/quicksilver name for the stuff, I forget the FelPro name for it..it will come to me.

I was talking on the threads on of the 3 large bolts that hold up the passenger side motor mount. a little on the the top of the bolt below the head . it act like an O-ring in case you do have a small leak. You shold always clean all threads and bolts, when putting everything back together.
