Yamaha EF2000iS Generator with LP/Propane conversion

my yamaha EF2600c can make full power on either LP or NG, tested many times with amp meters. Although, the surge recovery is not as good as when running on gas. I have run my 13,500 Mach III on LP many times.

Once again, blanket statements from people who read something...or something from another generator doesn't always apply. I thought we were talking about a yamaha generator. Although I don't have the exact model in question, I have real world experience to share.

Did not know it was a Polar Cub, you should be fine.

The Polar Cub 9.2 is rated at 1260 running watts.

I know it takes more to start it up, but I get favorable reports about Honda's EU2000 being able to handle it, so I'm hoping the Yamaha is up to the task. That, however, is based on gasoline. I won't know for a fact until I drop the coin and try it, unless somebody already knows otherwise. In that case, I'm all ears.
Thanks for bringing it up. It's an important consideration. I'm still on the fence about the value of the conversion, but I'm pretty sold on the Yamaha EF2000. Size and weight being big factors, of course. We have a 5000 watt generator at home that would require a very special occassion for me to lug it around.

EDIT: Update - Largely due to their dealer/parts accessibility and an easy extended run fuel tank, I bought a new, Honda EU2000 Companion from my local Honda dealer for $999 out the door. This was during Virginia's Hurricane Preparedness Tax Vacation. After getting a price over the phone, I asked the sales guy about them honoring the zero taxes on generators under $1,000. He started laughing because he thought I was joking. I told him to Google it and call me back. He called back. I went in and picked it up, no taxes. They didn't charge me their $49 "set-up" fee, either. I was the one laughing when he mentioned putting oil and gas in it for 49 bucks. Nice try. They put the oil and gas in it and fired it up, anyway.

I was concerned about it running properly at different RPMS. Does it work fine in eco mode where RPM is reduced if loads are low?

Been using a tri-fuel Honda 2K genset on propane with the TT for years. A spare 30 pound bottle of propane is loaded even if I don't bring the genset. No more gasoline to spill or go bad (unless the boat comes along). Also, I have NG at home.

If you look at the specs. on mh's generators it will give watts for gas and less watts for LP.

Does using propane really reduce a generator's electrical output, or could it be that that fuel consumption is higher for the same output? It is the same engine, same displacement, compression ratio, etc. And with an "over engined" generator like the eu3000i, would reduced engine power even come into play?

It's so much as LP not being efficient. LP does not have as many BTUs per gallon as gasoline.
But as said above, you don't need to worry about the carb gumming up. LP does NOT go bad.

The main advantage is that it won't have the carb gumming problems that gas often has when used infrequently...

So in a nutshell, the more you will use it the more gas makes sense.

Spot on here. What is the typical downrating for propane vs gas.

The 2000 probably won't run your AC.
