I need to replace my oil seals and maybe my bearing carrier. I was wondering how to get it off. It looks like there it a nut with a lot of teeth on it inside of the carrier. Do I need to get that off and how. Also is there anything I need to take extra precaution with and when I put it back together. Thanks. DOes anyone know the part number of the bearing carrier for a 1995 mariner magnum 40. Thanks
