The starter (and generator, if it has one) is 12V. The igniton system is a self-powered magneto.

Fuel mix is 24:1, TCW-3 outboard oil, regular unleaded gas.

Check compression before dumping any money into it. If good, then proceed. Put in a new water pump impeller. Maybe a carb clean/rebuild if you have no history on the motor. Check spark. And change the gear oil in the lower unit.
