We have a good quote from Onan on a 21.5KW gen-set for a customer. We are hitting hard our Northern Lights vendors for a good price on their 20KW also. We are replacing a Hat's MD4 20Kw reef material pile. I noticed the later Onan's are coming with the Kobota blocks rather than the Shibaura blocks that N L & Onan shared. I have always been a Kobota fan but also have no complaints on the Shibaura either. Onan has fancy electrical thingies. N L has relays. N L has their own generator end. Onan uses the stanford-NextGen windings. Gear driven raw water pumps seem to be better on the N L. The N L heat ex-changer seems to be more serviceable. We also need the N2K I/O. The Onan would come with the J1939 and N2K option plugs into that. N L has a non company vendor to use for N2K I/O. Eager to read what other members have to say about these two packages. If you have any history on me, You already know I'm not a Kohler or Worse & break fan. Please don't bring that crap (no relation) up.
