I use Permatex Form-a-Gasket, 3H. Lay the gasket on a piece of cardboard and paint the sealer on liberally. Then take a putty knife and press it out so that you have a very thin coat. Turn the gasket over and do it again. If the gasket says "use no sealer" just ignore that and use the above process. |

You will probably get several pros who will chime in with "never use permatex on an outboard." I use it all the time with great results. They make an aircraft version with a brush cap that is great for this purpose. Carbs and intakes are the only parts that I assemble dry. |

Hylomar in spray Can is best. If you have Silicon coated OMC head gasket then DON'T use anything. [IMG]http://i401.photobucket.com/albums/pp93/collectorinspector/Hylomar.jpg[/IMG] Regards B |
