I have a 1966 Super Seahorse Electromatic without a generator and need the wiring diagram. I bought a repair manual and a parts book and neither one had the diagram for the model without a generator. I just got motor and it has not run for 15 years. I think the ignition is wrong as the wire eyelets did not fit the screw head.

ALL Electramatic motors left the factory with generators. I don't know where yours went. You would be dead in the water with a dead battery.

Another option, buy a solar charger for your battery. That's no joke as they do it down here in FL.

This shows the generator, but easy enough to omit it for wiring purposes.

I have a 63 RKL-25 with a faulty generator and carry a spare battery, basically the same motor as yours. Lower unit requires voltage to power electromagnets in gearcase to remain in gear. In addition to generator, it would also have had a regulator which was in a junction box mounted in the boat near motor.

Generator that fits this motor is an autolite or prestolite 10amp unit. Both regulator and generator are a pricey. regulator can still be obtained if you look around a bit, generator more difficult to find. Asking price for generator typically over $100 and $75 for generator, and you would need special belt which is another $60ish.

might be easiest to run with extra battery in boat and look for parts motor that has your missing parts.

Running with an "almost" dead battery will cause the clutch to slip, which will damage it. Just so you know.

When I wire up the motor, the black with white stripe from the magneto gets hot quickly and smokes. Any guess as to why?
