Hi,

I am looking for a more efficient alternator for an old Yanmar 1GM
marine diesel. The original is 35 amp and I want to have something
between 50 and 60 amps. There is a bunch of webshops selling
replacements but they are all 35 or 40 amp alternators.

Does anyone happen to know a suitable replacement, a car alternator for
example? The best solution would be an alternator that also has the
sense-terminal for voltage control.

The newer single wire alternators come in a number of configurations. I
would expect you can get a 60 amp one to fit. Unless you really need the
external voltage control, are you splitting the charge to multiple
batteries? That requirement might lessen your choices some.
