In the "For What It's Worth" column, I lost my elder 2008 EU2000i in February at the height of the then cold snap. It had about 2500 hours on it with less than stellar maintenance. Put the rod up through the piston, scraped the cylinder walls and all sorts of metallurgical nastiness ensued. And So It Goes.

A friend and his brother in West Texas both run the Yamaha 2400's. First one developed an oil leak from the casing at 1600 hours. The second one started leaking from the case at the same spot at 1840 hours. Both are experienced genny owners and real regular in their care for their machinery.

Now, my second EU2000i (2010) has about 1500 hours on it and it will NOT operate in parallel with a new companion unit for longer than 15 minutes without overheating and cutting out ... a real problem as SWMBO desires A/C in her bed chamber whenever it gets to be more than mid-70's out of doors. As noted by many before, that is unusual behavior in New England, but you have to make allowances as she was born and raised in Louisiana. (It's a mindset issue, I think...)

So, my experience of Honda EU2000i's is a useful life in the vicinity of 2000+ hours (rough average of the two). It isn't like they owe me anything. The new Companion is even quieter than my old ones. I just hope they've cured the starter rope wear issue. Given a combined cost of $2200 (bought at end of season and/or Louisiana Hurricane Preparedness Sales) the fixed cost has been about $0.25/KWH plus fuel & lube costs. Fuel costs have varied a great deal in the past nine years. At no time has it been less expensive to generate our own power than to buy grid power, except the fixed costs of bringing power to just this one site in Maine would exceed $10,000.00 for poles and installation.

As always, Your Mileage May Vary...

I say Yamaha for the very reason Wil describes. What he described is exactly what happens to timing belt-equipped non-free revving engines when the belt breaks. The engine goes out of time, the valves hit the pistons causing them to deform then they scrape the cylinder walls and start tearing up the engine. Not ALL Hondas have the timing belt but the 2000's do.

Yamaha 2400 has a metal timing gear (no belt) that is all one piece with the cam.

There are more differences but this one is a major difference. There are those that would argue that those belts don't break that often but the potential remains resulting in engine failure. My dad, having a Japanese pickup truck engine with timing belt fail years ago, will never buy a vehicle with a timing belt- just for that reason. He got a Toyota Camry in 1997 (he was misled by sales on that one. When he found out otherwise, sold it in less than a year). An oil leak is quite different than a torn up engine. Additional information is that the Yamaha government engine life ratings are significantly longer

The hour-rating on the Yamaha and Honda are EPA-required specs for the expected life of the emissions system, not the engine itself. Neither Honda or Yamaha have any kind of "engine life" specification or warranty.

Caveat: I work for Honda, but the preceding is my opinion alone.

Yes, I like my Yamaha 2400, but will it run a 15k btu AC on a newer AS? (2014 to 2017), or will I need to upgrade when we purchase or next 25-28 foot AS?
