How to properly identify my older model Mercruiser sterndive

Katie,

Thanks for your inquiry and the opportunity at earning your business. Unfortunately that Sterndrive serial number is too old to look up in the Mercruiser Parts system and Mercury Part Diagrams. However using Using the link below you can read a couple of technical articles that should help you with that. In either case I will be glad to assist!
