I hear what you are saying, but seems to me you're re-inventing the wheel. Why would I want to hook up a small gas engine to an AC compressor when a small generator will run the AC unit as well as any other 110v appliance(s) I have on my boat. I can even take it home with me to use as a back up generator for those instances I lose power.
Not saying it is a bad idea, but if it was a good idea, someone would have developed one by now.

I used to have a 4700 BTU CruiseAir on my Catalina 30. On hot, sunny days here in VA, it didn't do much, but once the sun set, it started to be comfortable and by 11 pm, it was pretty cool in the boat. If I left the thermostat in its coldest position, it was very cold the next morning.

Re: Generator to run 6000btu window ac

Thanks for all the suggestions gentlemen Oh I should certainly mention I no longer have my Oday 22, I now have a Hunter 33. I have to update my profile. So far the AC has been doing a great job at keeping the boat cool. Had a couple fairly hot days and it done well and this was setting it at 72. At night it gets downright freezing in there. Guess I will have to see how it does in 95+ degree temps soon but I think it will still do well.

I been looking at different generators, seems like the Hondas are rated the best. However I also seen others (such as Hyundai Hy2000si, ETQ IN2500i, and Generac IX2000) pretty high ratings on those and about $300 to $400 less. However, I am still leaning on the Honda EU2000i. I mainly want it to run the ac and a small fridge.

First of all, I've never seen or even heard of anyone running an AC unit off of the boat's main propulsion engine.

Secondly, the OP has a 22 foot boat and I'm guessing, it has, at most, a 6 HP outboard. It's going to be pretty hard to put a auto type AC unit on an outboard.

That's the level where sustained exposure will begin to cause hearing loss.

Re: Generator to run 6000btu window ac

I'm looking at the Ryobi 2200, supposed to be 53 decibels - same as the ubiquitous Honda 2000 but rated at continuous 1800.

I read claims of 90 decibels. It is really not too bad for my purposes in the marina during daylight hours. In a quiet anchorage in the evening or morning hours, where sound carries easily over the water, you would probably quickly antagonize everyone within a half mile.

Re: Generator to run 6000btu window ac

I have both a cheap 1000 (advertised) watt 2 stroke generator and a 3500 watt (actual) 4 stroke generator. both are loud, but in different ways. The bigger genny is a steady
"ERRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR RRRRRR" while the small one pulses..."RINGDADINGDADINGDING..DaDINGDINGDING..DADINGDINGDI NG...da......RINNNNNNNGGGGGGGGGG!!!!! DADINGDINGDINGDING...." The 2-stroke bothers me more, because it always sounds a little bipolar, like it is not sure whether it is going to seize up and quit or whether it is going to go tearing across the boatyard and start dryhumping a passing Vespa. i always feel like i have to keep an eye on it when i use it, while the 4-stroke generator is just like a bass player- dependable, dull loud, and just keeps doing the same thing until made to stop.
