And make sure whatever you get is ignition protected. Very important with a gas inboard engine.

Re: Atomic 4 Alternator replacement

Some of the older alternators had an exciter wire, which provided the higher amperage when charging. You should be able to find an online wiring diagram for the replacement, if not check Moyer Marine's site and you will probably find the answer to your questions.

Re: Atomic 4 Alternator replacement

We just determined the (original) alternator on our (vintage 1967) Cal 30 is shot. Spoke to MMI, who recommended their 55 amp alternator but said mounting arrangement for it differs from the old one and that mounting the new one might be "involved". Went to alternator shop and was told Delco #8903 (61 amp) would be a good replacement for the old one, with a similar mounting arrangement (which makes it attractive); however, it has only one wire (no field wire, as with the old one) and the change in wiring makes me nervous because of that (I am not an expert). Does anyone have experience with: a) mounting the new MMI alternator to an old engine, or b) using the Delco to replace an old alternator?
(I apologize if this is a duplicate post,.. am just learning the ropes on posting)

Do you happen to recall who rebuilt the alternator? I'm in Towson. Thanks

Is this the one you used Tom Mays? NEW Motorola Leece Neville 12v 51 Amp Alternator: Alternators &amp Alternator
Leece Neville is a recognized and respected brand. Listed price is a tad cheaper then MMI but not by much.

Take yours to an alternator shop and see what they can do. You might be surprised at how helpful and knowing and reasonably priced some of these guys can be.
