I was just given a 1974 9.9 with electric start and I want to know if it has a charging system?
Can run it without a battery attached or will it cause some grief?
What voltage battery would I use? 12 volt?

The electric start version of the 9.9 hp has 12 volt battery charging capability.
If you run it without a battery, or if the connections corrode or come loose, such as with wing nuts, the rectifier part of the charging system can be damaged.
