Hi, My 2hp Yamaha 2b old head gasket has been reused. It has a slight leak, you can see the water slight drip at the bottom of the head. The mechanic says it will go away after using it a few times.He says the salt will seal the leak. Is it possible? The motor runs well and stays cool, no water seem to be entering the cylinder. Should I take his word for it or replace the gasket. A new gasket cost R360.00. Does anybody out there know if there is a replacement gasket which is cheaper? Your help would be appreciated.
