Hydraulic Drive Alternators
 

I have seen some comments recently about boats with hydraulically
driven alternators but have been unable to locate a source or any
additional information.

Does anyone here know where to locate either?

Anyone familiar with pros and cons vs belt driven?

I have used hydraulic drive alternators. I dont recommend them unless you MUST
locate an alternator in a place where belt drive is impractical. Complex, not
nearly as efficient as belt drive and it generates much more acoustic noise
than you'd expect.
