Many parts can often be purchased at an auto parts store if you
know the right numbers to ask. Sometimes the store will know what
parts fit the Atomic 4, but most know nothing about marine engines.
The Annapolis NAPA Auto parts store is one of the exceptional
ones; you can give them a call at (410) 263-2695. Cobe Marine (1-800-414-COBE)
in Pasadena, MD tells me they've got a tune-up kit with points, condensor, cap and rotor (Sierra Products #18-5268) as well as other Atomic 4 parts.
I've compiled
a list of part numbers over the years, some of which I've personally
used and some of which I've gleaned from others. I'm no expert
and I don't guarantee anything. It's best to take the old parts
with you to compare. Remember that a lot could have changed since
the boat was delivered. And please,
let me know
about any errors or additions.

There are two distributors used. The older engines (serial numbers
71000 through 170507) had a Prestolite distributor which, I'm
told, is the same as that used in a circa 1944 Willys Jeep. Newer
engines (serial numbers 170508 and up) came with a Delco distributor.
Verify which distributor is actually installed in your boat; don't
just depend on the serial number of the engine.
For the Delco distributor, you'll do well at the local auto parts
shop by telling them you've got a 1974 Chevy Vega (thanks to Gavin Peters
for that suggestion). That gives a different condensor part number than
I've got listed, but I guess that's OK.
A number of water pumps have been used over the years. For raw-water-cooled
engines, the most recent (and the replacement for previous models)
is the Oberdorfer M202-3. The Oberdorfer M202-7 has a taller
"shoe" for higher output. This shoe is interchangeable between
the models.
