Arild: Thanks for your post. You make some very good points about the Honda. We love ours too much and wouldn't leave the dock without it. I feel that a big advantage of the Honda is that nearly everyone else has one. This pretty well neutralizes the noise issue since, if I run mine now, how can the guy in the next boat over complain since he knows he will be running his later.
Another benefit is the Yahoo group devoted to the Honda at: http://autos.groups.yahoo.com/group/Honda_EU2000_Generators/ This group is more like a cult of people who love the Honda EU2000i so much they can't stand it. If you can't find the answer to your question here, you aren't going to find it. My only complaint about the Honda is its small gas tank, but the Yahoo group offers many, many ways to add a larger auxiliary tank. Some day, I'll get a round tuit.
