Being on the island of Pohnpei in the Federated States of Micronesia, my choices were limited. I did finally find a Yamaha EF2400iS generator(LOTS more money). A friend on a neighbor boat had one and let me borrow it to make sure it would run the Freedom 20. Worked like a charm so I returned to town and bought it. Once on board, I added oil
and filled the tank. Started up at first pull and my Xantrex meter showed the Freedom was putting out over 90 amps when it first fired up. It hasn't been any where near the number at any time we used the Honda. It slowly tapered off as the generator ran but it charged my batteries in about 2.5 hours instead of the normal 3.5 to 4 hours the Honda took.
It's much quieter than my Honda which makes fore happier neighbors here in the marina(so's my wife).
May be more than we needed but I have more faith in it(had a Yamaha before)than I think I would have had in the Generac.
