If you buy a real alternator, not a boat toy, you won't have a
problem.

If the alternator has "hot" rating, not a "cold" rating, then it will
carry nameplate rating.

Marine electrical devices are rated for a 50C ambient, not 40C for
land based installations.

These days, the above will limit you to Leece-Neville or some Delco
models.

The rest are basically toys.


As a former L-N design engineer, yes, my reply is biased, but
truthful.
