Looks interesting. The exhaust extension looks interesting as well. I wonder if a flexible extension going down into the water would reduce the operating noise? Do you have any info on the exhaust mod?

I don't think it would like the back pressure of the exhaust in the water.

The conversion is easy to do. There are a number of carburetor manufactures out there that sell LPG conversion kits.
I converted my 5000 emergency generator at home to run on natural gas.
Now when the power goes out it can run all night with out me having to get up and refuel. It also has a Low oil shut down just in case.
The conversion was about $200 and about 30 minutes of work.

I thought about doing it to my EU2000 but then therre was the problem of storing a propane tank on the boat plus trying to get the tank refilled at a marina.

I agree, it wouldn't be worth it for boating use, but I'm more interested in the exaust extention. I've heard the speculation that the back pressure would not be good for the unit, but I haven't heard definitive feedback from anyone who has tried it.

I agree, Doug! I would also not be too excited about the whole LPG idea for use on one's boat!


I'm still hoping that Honda will some day design an affordable liquid cooled/wet exhaust marine version of the EU2000 and EU3000 generators!
Wouldn't that be nice for the guys with smaller hulls?


As for what appears to be an exhaust extension..... for all we know, that may have been used during testing only.

I think so too. It's probably feeding into an exhaust gas extractor so the test room doesn't fill up with CO.

Unfortunately not. What I can tell is the genny was running
and the exhaust extension was laying on the floor. Was a pity that it was shown by a company that sells a lot of stuff. The sales I asked about it called a "specialist" who told me that it was running on LPG. But I took the foto with the tel. number on the tank so if I can't find the info at Honda I can call them.

If you think a big Hall on an Water sport exhibition is a test room, yes you might be right! And what ever you may think about the Germans, you can't deny they have some experience with it, don't you think? :rolleyes:

Only that it cost more to buy it like that and never gets used.

OK, But we have had some discussion up also about LPG running the engines. Especially with boaters from GB. Although it will run perfect the difficulties encountered like filling the tanks and a much heavier tank, higher LPG usage and less distance are contra productive for the use of LPG today, we all agreed on . The big exemption are the ski boats they mostly run on LPG over here. Running a Genny on LPG isn't a bad idea at all if you can over come some of the above aspects. Being able to fill the cylinder at the local gas stations fore sure would help a lot for usage as seen with the Honda. What I really fear is if the Honda can handle the higher heat of the LPG!

I suspect the ski boats use LPG because of cost.
That should not be a factor on a Honda as it uses little fuel.
The extra cost coupled with the safety issue of LPG just doesn't seem worth the cost or risk to me.
I once had a diesel motorhome with a propane running generator. I suspect that also was because of the additional cost of a diesel generator. While it worked well, I didn't like it for a couple of reasons.
It used the same limited fuel as my furnace and if I ran out in cold weather I had no backup genny for electric heat.
Propane wasn't and still isn't as easy to get as gas or diesel.

I once


The use of LPG by ski boats is done for costs only. The same goes for cars and if it was possible for bigger boats too!
What came up at first when we ran into the LPG Honda was it done to be economical if you use the Genny for a long extended time. LPG here costs 1/3 of gas and 1/2 the price of Diesel. Gas at the moment is € 1,44 the liter and diesel € 1,06 per liter. This are high way prices. for Marina prices add about 10%. As we have about double road tax for Diesel and LPG, but not yet having a boating tax and the much higher price of diesel of engines it's an easy calculation, that LPG would be the way to go, if there were no nasty things like where to get the LPG on the water? Not to name those heavy big LPG tanks, the weight they will add and the space they will take. Costs of the LPG installation about € 1500-4000,00 You already have a good installation for about € 1600-1700. So that isn't a real issue compared to the price of Diesel engines.

First off this is no major leap by any means. The US Govt had a fleet of Chevy 350 Pickups that were of 1972 vintage. If I remember right they even had or once had air bags. I drove them when I was a guard at the Federal Prison near Denver. Believe me when I say it's no big leap unless you can get cheap propane. The first thing I noticed was that they stunk to high heaven idling and tended to give you a headache. Also propane gives you a fair bit less mileage, something like 20 - 25% roughly.
Those trucks we had consisted of a switching mechanism over the carb which looked about as complicated as a simple electromechanical cut off and that cheap looking manifold. Then there was that 4' long 24" wide propane tank that took up a quarter of the box.
So at the end of the day you have an equally loud boat with an excessively large and very heavy fuel tank. It has to be filled by a special valve as barbecue bottles are. For all of that it won't go nearly as far and if you troll downwind it will give you a headache. Where can I get me one of those.............................:confused::confused::confused: Such a deal.

Who said it was? ;) About LPG in cars, I had my first LPG installation built in my first Audi 80, some where in the early seventies. But that's an aside. Walking through the boating lovers lane at the Dusseldorf boating show, what is written to be the biggest boat show in the world (what's in a name?) When I saw that Honda genny running on LPG and considering the tremendous love by US BOC members for a BBQ running on propane instead of charcoal, I just thought as I never saw one doing it , it was nice to show that also a Honda genny can run on different fuel than gas. And sorry but that's all Folks! :rolleyes:

Well done Roel. Yea, I would appreciate a translation. I did notice that the page has the word "marine" on it. Maybe this exhaust extension is designed for marine use??

I tried it last year seemed to lose a lot juice from my new 2000unit .......would not even keep the freeser below freezing 32degrees /don't know if I did somthing wrong or not but the difference in sound from the unit in or out of the water was not enough to risk it again ... Cost of the flexable hose "ouch" unable to use it for anthing else
