    I have a salt water back ground, so always look at things from a corrosion prevention point of view….So, I always recommend cleaning the block and bolts threads, then coating the threads/bolt shanks with the OMC/merc/Yamaha gasket sealer. I usually coat the outer surfaces of the gasket with gasket sealer also. Some head gaskets do not require sealer, that is usually printed on the gasket….
