Steve: IMO the Honda works so well as it is. My feeling is if it ain't broke don't fix it! As for the snow blower idea? Hmmm, well it is a shame to have the LEMCO motor just sitting around in the off season. If I were more of a tinkerer I might consider it. I'm sure some here on the list could make one in an afternoon. Wonder how much snow you could move with a 9 HP electric motor? I think Myles posted a link a few weeks ago to a manufactured one. It sure would have come in handy this week. I think I'll stick with just using the Honda for just heating the house and melting the walkway ice for now.  Capt. Mike

I was wondering if you converted it to a snow blower. :o) I was getting at using the Honda with an inverter to 48vDC. I have no experience with the Hondas so don't know if it was feasible or not but just thought for emergency runs or distance that it could be used in this manner. Hope you get down to the Chesapeake sometime, we can compare notes. Steve in Solomons

In the ideal world it probably would be most efficent to use a generator that puts out 48 volts DC (or whatever voltage the EP systems needs). But, does it weigh 47 lbs and can you lift it with one hand like I can with my Honda 2000i? Is it as quiet and compact as a Honda 2000i? I have not seen one. Yet. I've seen diesel generators that can put out 48 volts. But, personally I do not want to go back to have another diesel ICE installed below decks. I spent way too much time in the cramped engine area trying to get my old diesel started let alone maintaining it. If my Honda breaks I can carry it off the boat to be repaired or buy a new one for under $1000. The diesel genset costs $5k+ I could buy a lot of Hondas for that same price. BTW I also found another use for my Honda generator in the off season:

Let me ask this question. Wouldn't it make more sense to output a genset to an inverter and take the normal 120v output to your usable motor requirements, most of you are running at 48v? You could split off before the inverter to maintain your 12v requirements and in the case of 48V motors have a long range directly of the genset rather than run a charger to recharge before continuing. I'm not good with the math but I would think in most cases 10A off the 2k genny at 12v would be more than enough to handle most needs so let's say you then would have 40A to run the motor as long as you want. Make sense? Steve in Solomons Is it feasible/advisable to entertain the idea of keeping a small 1,000 or 1,500w generator on board for emergency backup and also potentially the option to recharge batteries after a stretch of WOT motoring to help compensate for the massive and quick powerdrain. A rough guess I'd think would be 100 minutes of charging w/1500 watt gen would be needed after 10 minutes of WOT, but maybe if you only burned for say 3 or 4 minutes at a time and ran it for 30 or 40 minutes, then we'd be talking more realistically/practically/feasibly. Especially since efficient generators of that sort get over 8 hours of runtime per gallon, though maybe only at half power output, so maybe 4 hours to be more reasonable, but still gets you a lot more practical use cheaply out of such a setup, no? You can get a used honda eu2000i for under a thousand dollars USD (even more powerful for my very rough calculations), so maybe 30 minutes of runtime for 4-5 minutes of burn. Starts to sound a lot less daunting than riding the edge of oblivion for 10 minutes WOT max for the day's motoring IMHO, and you could probably get that generator for closer to $500 or $600 and these are super quiet and clean burning generators.
