I have a 1993 115hp Johnson outboard that I am getting ready to install a water pump in.I have a complete kit and the instructions call for using gasket sealing compound, adhesive 847, triple guard grease,and moly lube at various times during installation. The Johnson dealership's parts salesman said I didn't need these items, just put the new one back together without them. I have moly lube and marine grease.Can I get away without the gasket sealing compound and the adhesive 847? My Seloc manual says to use these items also.Any help will be appreciated. Jim Baird
