This engine was pulled from a working sailboat that I bought then decided to scrap. I have decided to sell as I don't need a second engine.
The Atomic 4 has been one of the most popular gas engine for sailboats over 40,000 produced since the late 40's though early 80's. With very little design changes

That thing sounds really good. A sweet sounding motor, like music to my ears.

My dad was a chief engineer. He had an old atomic 4 he wanted to rebuild but he died unexpectedly. He said those motors were great. I never saw one run untill today.
