Welcome Wayne! If you are going to mess around with old outboards you might need to learn to make your own gaskets. There are some good tutorials on utube. Mister tubs is a master gasket maker among other things and his videos really helped me. Head gaskets are the biggest problem. Many Pre 1950’s motors do not have head gaskets so usually jug and manifold gaskets are not that hard to make. Practice makes perfect! You need a set of hole punches, maybe one of those tools to punch holes in leather, sharp blades and some patience.
