Question Johnson Ignition Amplifier vs. Car Coil

Hello great minds. My older brother gave me a 1968 Johnson 55 hp about 10 years back and it's been sitting in the shed since. Well I went out the other day to do something with it and found the mice had the same idea. The amplifier is shot and some of the wires are too. I can splice the wires and fix that, but about the amp is a different story. Have any of you heard of replacing the amp with a car coil and resistor simply because for a new amp it would cost about $300.

They must place a bunch of stuff in that box that most likely can't be replaced by a simple coil and points. It must be a capacitance discharge ignition. You might look for one on eBay, but watch for the seller's feedback if you are a new eBay user.

If you can get a schimatic of the wiring, you could probaly come up with some home grown set up. Is it points ignition?

I have a few motors out back and a large amount of oem parts get me a part number, I can get you a good deal if I have a used one.
