No worries, Dave. Just a mix-up - it does seem an odd thing to have two so similarly named products offered by one retailer!
As I look at the specs, it appears that the two (Honda/PowerHorse) are very different in some important ways. You're right, the PowerHorse has the 30A plug, and that could be important to an RV owner. It also does have the dual-setup cables and, again, to an RV owner or to someone wanting to use it as a backup genset for a home this would be an important feature.
Both generators have the 'copper wound' heads, so that's a wash, and they're also about the same dB, too.
However, for boat owners the PowerHorse may have some drawbacks as opposed to the Honda. First, it comes with only a 2-year (versus Honda 3-year) warranty, and maintenance and repair parts for the unit may be significantly harder to obtain than for a Honda (air filters, carburetor rebuild kits, etc.). Indeed, I'm not sure where you'd get parts for the PowerHorse... do you know?
In addition, there are a wide range of accessories made or the Honda (see the Honda website and places like eBay & Amazon) which add flexibility to the unit, including such things as
propane & natural gas fuel conversion,
extended run fuel hookups,
lock-down brackets and
boxes,
oil-changing devices,
fabric covers (including a nice "Honda Marine" one in Sunbrella blue - I couldn't resist buying one for mine) and even
attachable light units (though the latter has little use on a boat!).
There's also one other very important difference... although both units have a standard load rating of 1600 watts, the PowerHourse can sustain a surge load above 1600 watts for only 4 seconds, whereas the Honda can sustain a load up to 2000 watts for up to 30 minutes. This could be important to those wanting to use more hearty AC units on the boat or devices with significant surge on startup.
Most importantly, though, the PowerHorse lacks a feature that could be particularly crucial to boat owners... it doesn't have a 12V output battery charging outlet, so it can't be used to directly recharge the boat's batteries. You'd have to buy a battery charger and run that off one of the 120V outlets. When I purchased my EU1000i that was one of the most important features to me, and I purchased the
special Honda cable that's offered to connect that outlet to my batteries (it's helpful, too, that it's a really LONG cable!). It will recharge at about 8 amps, so it charges almost as well as running the motor (10 amps). I was wary about having 120V extension cords and battery chargers running across my decks while out on the water - it just seemed a lot safer and much more simple and efficient to directly charge the battery at 12V.
And I know it's silly, but the cover is kinda cool... it exactly matches my sail cover and bimini.
