I have an older yacht with an Atomic Four engine. I am a diesel mechanic by trade but truly love the simplicity of this motor and the reliablility it has given me while on the water.
I have recently added a PCV valve to my engine and converted from a 2 blade to a 3 blade prop to gain some RPM's. I went with two products from Indigo Electronics and was pleased with there service. Check them out at:

Another wealth of knowledge is Don Moyer of Moyer Marine. What a true delight to be able to call up and speak with "The Man" who is a legend in the Atomic Four Community. Their business is truly a family affair and they offer tips and personal truoble shooting without you having to pay them first. They truly cater to the customer. Check them out at:

There are many other sites out there posting repair part numbers/cross references and user manuals but I am limiting this post to part suppliers that I have dealt with.
Hope you found this helpful!
