What can I use to cement the new seals in my 25hp. Johnson? The upper seals had threadlock or something on them, I had a hard time getting them out. Is there small tubes of a marine glue I could use? Everything is out and cleaned. All new parts are ready to go in. Any help with my reassembly would be appreciated. Does anyone happen to have a 6 bolt tailpiece for this motor that they don't need? Mine is in bad shape.
