The Honda 2000 generator has gotten a lot of discussion on the site particularly as it pertains to powering the boat’s AC units. I wrote a previous post describing my early experiences with this and gave mixed reviews. I had no problem powering the stern AC unit but did have difficulties with the 16,000 BTU main unit.
This year, I installed a Dometic SmartStart to the system and have had no issues running the main AC unit now. http://www.dometic.com/enie/Europe/Russia/Products/Marine/Marine-Leisure/SmartStart-Soft-Starter/
The SmartStart lessens the initial amp draw of the AC unit as it starts up. I give this solution a strong recommendation if you expect the Honda to power a large AC unit.
