I have fixed many different problems with my Johnson so far. Thanks to everyone on this site. I wouldn't have been able to do it without you guys. Thanks. I took my boat out today and drove for about an hour. It drove great and didn't die once. I noticed grey looking foam grease coming out of the exhaust. I am assuming its the seal on the lower unit but I am not sure. Does anyone know what this could be? If it is the seal. Does anyone know how difficult it is to change or how to change it? Thanks so much!
