zena marine alternator

They overbuild them for heavy duty aplications. Mostly welding and power generation for ambulance/fire and the like. Gang them together for 5 and 600 amp continuous dc welding.

+1 on Leece-Neville large case alternators. Unlike small case alternators, these will put out their rated power even when hot. Very solid.

I had a Leece-Neville on my last boat and had it rebuilt and some diodes replaced (the alternator had given heavy service for six years and the rebuild was about $100). These guys did the work and I was very happy. I did it all by email/mail.

Toledo Truck Parts

They also sold alternators and seemed quite familiar with marine applications so I think a call might uncover some great options. These are the kind of guys who seemed like they had bins of mounts hanging around (or if they couldn't find one they could make it in 20 minutes).

Once you get past 110 or so amps you have to go to twin belts. You'll need to think about the pulleys on your engine.

I need super clean AC. The true sine wave inverter I use creates and conditions 120vdc very well. It has also been extremely reliable.
Maybe a ventilated box or something over the genset to deal with the spray. Regarding the quality of the output I think the Honda EU2000 makes pretty clean AC. Have not hooked one to my scope but the power is from an inverter and not a standard generator winding and have heard several people comment that the output is very clean.

Sometimes it's necessary to state the obvious for the benefit of the oblivious.
