Wow I'm really impressed! You guys know your sh........stuff!

'sticker, if you're flush with cash, buy a honda or yamaha genny. If not, one of these honda clones like these guys have are the next best thing IMO. There are several different brands out there that appear to be the same generator with different color paint and/or lay-out of the recepticles.
Keep in mind they weigh about 100lbs ready to run. That would be an issue with the 11 foot boat.
