|zeehag||before my battery charger died on my formosa i connected it with my shore power cord and an adapter----worked fine--now i need to save for another charger .... lol ... i believe your combination will work--if it plugs into the machine and the boat , ya got it!!!!---ps--the combo didnt burn out the charger---it was an oooolllldddd one and got wet in the winter from a deck leak in my leaky teaky, go figger...lol.....should work for a long time on yours----|

I just bought a Honda EU2000i which I have not yet used and have a related question;
what do you use to connect it to the shore power inlet on the boat?
I was thinking of using one of my 25' shore power cords and one of these adapters;
Would that work? Any better methods?

|zeehag||6 yrs ago i swore i would never use a genny on my boat-----5 yrs ago i got a honda 1000eu----hated it--the song varied tooo much at idle--i traded it and some more money for a 2000eu honda and loved it until the thing stuck a valve --then i bought a briggs and stratton 3250--hate it---waaaaay tooo noisey----fixed the honda and now am thinking of saving allllllll my extra dollars for another one---they survive mistreatment and abuse and they are able to charge my boats' systems efficiently without the rabid noise problem---i always point into wind --unless current overtakes the wind speed---but the sound factor is such i can charge until late into night without bothering anyone else but myself--oh--i keep it on my cockpit on the lazarette-aimed astern---ran around in my dink to see how far it can be heard---honda--only as far as my own mooring lines----briggsy-----alllll the way to the other side of the moooring field!!!!! honda and yamaha and the big names are excellent---the off brands have made in china on them and last only 3 months-----honda rules!!!--ps--i have neither tv nor airconditioning---neither is needed on board a boat having flow - thru ventilation.....(my 2 cents)|

One thing to think about, re the off brands. I'm sure it is as true today, as it was in 92 when I bought my EB3500 Honda. Some of the charging electronics are not as good as what goes into the Honda's. If you put a Volt meter to the off brand, the Volts, altho it might be the Amps or watts, will vary below and above 12V by 2 maybe even 3 volts. Where as the Honda would not vary but by .1Volts, and one can run a computer with it, where as you can not with an offbrand.
My dad used to work for a regional telephone company, and they Used Honda's or equal for critical electronics when the main power grid shut down, but on the trucks when they needed portable power for tools, they had off brands.
My .02 on this. I will not say that Honda is the only genset with these tighter specs on the power output, I believe yamaha and some others are the same way, BUT it is worth trying to figure out what type of power you want.

Back on the topic of generators, does anyone know anything about some of the off brand "suitcase" gensets?
Sounds like there are a lot of the Hondas out there. But I have also come across a few that a significantly less in price. Such as:
All Power America Portable Generator 2000 Surge Watts, 1650 Rated Watts, Model# APG3010 | 1,000 - 4,999 Watts | Northern Tool + Equipment $330
The honda seem to go for around $750 used to >$1000 new.
The noise spec does appear to be worse. The one above is 68 dB. The honda is 53 to 59 dB. That's more than 3X quiter, which is fairly significant. Funny how the price is almost exactly proportional to the different in sound emission!

Peikenberry answered this perfectly, Wind Magic. I would only add that diesels burn hotter and under greater compression pressures than little gas engines like the Atomic 4 (ideal cylinder pressure of 95-115 PSI, if I remember correctly). They also tend to be heavier built, CC for CC. A short run will not heat the block equally entirely throughout the block, and as it's been explained to me, uneven heating can lead not only to the contamination issue mentioned above, but to microscopic fracturing of the metals due to uneven expansion and contraction. A diesel brought slowly to operating temperature and then kept there could indeed be expected to run for years.
Sailboat auxiliaries are kept off 95% of the time, run briefly, and then sit in a cold bilge again for a week. From what I know of the thermodynamics involved (a diesel is after all, a sort of elaborate kettle or a bolted together bomb), the way in which we typically run our auxiliaries is not ideal. I run my Atomic 4 for a couple of minutes before departure, mainly to confirm I haven't got spider goop in the vent (it will slow and stall as the weak fuel pump is overwhelmed by the vacuum in the tank). My diesel goes on for 15 minutes before I leave, and I try to avoid sudden throttle changes until I read a nice warm block temperature. Racers, on the other hand, are always late for the start line, and fire up their diesels as the last crew jumps on and then belt out to the course at seven knots for 10 minutes, and then shut off the engine. 150 minutes later, they repeat the exercise and then park the boat for six days in a basin with 10C water.
Which sounds better?

The recommedation for not running diesels for short periods is because when cold, diesels produce a lot of soot and acids that accumulate in the lubricants. When they are allow to get up to normal temps they burn those off and produce far less soot. Over a short life, that is a few years, it really makes no difference. But over the long run (no pun intended) of many years, it can shorten the time between rebuilds. But diesels are generally so much more reliable and need so much less mantenance than a gas engine that it really doesn't make a lot of difference.
Actually a diesel is happiest running without ever stopping, just keep feeding it fuel and lubricant. Some of the diesel engines that power aids to navigation for the USCG have been running almost continuously for ten or more years. I have heard anecdotal claims of 20 years for diesels in the artic that power oil company equipment.
John, thanks for your support.

We've had some informative discussions about this same topic in the past. Here are a few threads that I quickly dug up:
I haven't read PEikenberry's article, but we are of the same mind on this subject. In one or both of the threads above I cited the relevant USCG and ABYC guidance that strongly recommend against the use of portable gasoline gensets aboard recreational vessels.
