Hi, I bought mine on ebay last year. I paid 85-90 bucks shipped. It's a genuine Hitachi 55 or 60 amps fully insulated with the exact same connections / look / mounting as the original Yanmar (I think they are made by Hitachi). I took the opportunity to throw in a new belt as well. It was a plug
Take a look at Spider Marine. They have a new Hitachi 60Amp alternator for the
3GM30 listed for $120.

All,
My alternator is putting out too much voltage (15 volts) It s a 35 amp
Apco with an internal regulator. Rather than trying to have it rebuilt I
am thinking of buying a new alternator. Is there a higher amp alternator
that will fit the single pulley without breaking the bank? I don't want
Good choice on the AGM. They have proved them self to me.

You can buy brand new yanmar alternators on ebay for ~$100. It sounds like
the sensing line might just be bad. Where did you measure 15v? I would
remove, clean and inspect all of the connections to the alternator. Then
with the engine off verify that the voltage at the alternator matches the
Careful getting a new alternator with internal regulator if you are
planning to get AGM batteries. The AGMs need slightly different charge
profiles to ensure maximum longevity. The charge profile of the internal
regulator won't be able to be changed. Also the internal reg won't be able
to be
