We're looking at the above 2 brands. Any comments on either brands would be welcome. Suggestions on other alternatives are also welcome.
Up until recently Onan has always been considered crude in comparison to Northern Lights, they were always noisier, didn't run as smoothly, made less stout, engines didn't last as long, and cheaper. The new electronic series is starting to change my mind on them after running several. They run much quieter, nicer and so forth and so on. But also more complicated with sensors and so forth. I definately feel they have surpassed Westerbeke and that the Westerbekes are pretty crude running nowadays in comparision.
I also have experience with a 16kw Northern lights and it always ran great and also a few 55kw northern lights. Both ran very smooth, were very very simple to work on, very quiet, used very few wear parts, were designed to go many many thousand hours. Northern lights would still be my first choice given a fresh install and space limitations.
