Not sure if you know this or not, but your motor is a 1976. If you're looking to do major repair, this manual will tell you step by step how to do it all http://www.eastcoastmarineservice.com/manuals.html#Seloc 1406 (SEL1406) If you're looking for basic maintenance as well as minor repairs, the owners manual should help you out with that http://www.eastcoastmarineservice.com/manuals.html#Owners66toPres (Mercury Outboard Owners Manual 1966-Present). Hope this helps, anyone that can provide better manuals, feel free
