Client Critiques
This is a pretty high good quality unit, nicely designed. I chose it more than the Honda Eu2000i mainly because it has a fuel gage and is a hair lighter (2 pounds), and liked the styling much better. Specs are so close it's a tie... the Yamaha unit specs a bit quieter in "eco" throttle but the Honda specs a bit quieter at complete power. Prior to this invest in I had bought a Honeywell inverter generator (a substantially much less expensive Chinese-produced knock-off) from Costco which I returned, for the reason that I was unimpressed with the Honeywell unit's high quality and noise level. Though the price distinction is key, you get what you pay for in this case. Everyone hunting at the less expensive knock-offs must really take into consideration that a 5db raise in noise level is a major distinction, the way humans perceive it.
The most impressive point about this unit is how quiet it is. Even at full engine speed you can stand about 6 feet away and have a typical conversation with no raising your voice, or talk on a cell phone with out undue distraction. It features an "eco" setting which tapers down the engine throttle and noise when complete load is not necessary. At half-throttle or much less, from about 6 feet away it is about half as loud and amazingly quiet. I implemented it to run a 50-amp 12v battery charger and at full charge level the charger only expected the generator to operate at about half-speed, and when the charger tapered down the charge level to beneath 30-amps the generator became so quiet I literally forgot about it. It is Substantially quieter than my boat's inboard diesel engine, and a lot more effective than running the main engine just to top rated off the batteries. I also implemented it to power a heavy duty 120v grinder and it had no problems supplying the needed power, even on electric motor begin-up.
I got this mainly for charging our boat's batteries at anchor but I also wanted the ability to run power tools. The lighter 1000-watt inverter generators could simply deal with the charging application but not the much more power-hungry tools. Getting the added power also indicates the eco-throttle will most likely kick in earlier and the unit will operate quieter. The number-1 obtain criteria was "quiet" because I do not want to be distracted by incessant noise or be a undesirable neighbor in anchorages. The Honeywell was not quiet sufficient in my opinion.
If generators are abused it will lead to regulations banning them, so an appeal to other boaters and to campers: Please do not settle for "low-priced". Get a improved top quality inverter-generator unit that is quieter so you reduce noise pollution in get-away locations. (Leave your "contractors generator" at dwelling!) Also, please be considerate of neighbors and limit operating it to instances/areas you aren't as most likely to disturb other individuals... and do not leave your boat or campsite though it runs and runs. We all like our electric conveniences, but if you genuinely want 120v power alot more or much less regularly you ought to either remain property or get a dock/parking space where you can plug into "the grid". It really is rude to disturb others who are trying to get away to locate some peace and quiet.
Unfavorable: The unit ships devoid of engine oil, so you will need to shop for a quart of common four-stroke engine oil and fill it. You will also desire a funnel, and a pan to catch excess oil. There is no dipstick you have to have to fill to the level of the bottom of the filler hole till any much more runs out. It makes use of much less than 3/four quart. I consider they really should have included the needed amount of oil, and a plastic filler container with a spout, marked to show the appropriate quantity of oil to use.
Update two/22/2012: In general nevertheless particularly happy with the unit, but checking oil level is inconvenient (you will need to open the case with numerous screws) and altering the oil is a messy operation involving rags and clean-up since there is no neat way to capture the waste oil or overflow directly into a container. I consider the next generation of this product need to improve on that design issue and offer a dip stick or oil level indicator that is either externally accessible or located behind a speedy-access panel.
Update eight/29/11:
Getting owned this for nearly two years now I would add the following:
1) I have identified that it has adequate power to run the charger AND the hot water heater's 120v heating element at the identical time. It is near-max (running complete speed) but does not light the overload light when performing that and the charger is in bulk phase. Nice when you happen to be in an anchorage for a couple of days and haven't run the engine. Why run a 57hp diesel just to heat water and charge the property bank?
two) If I shut off the fuel and let the carburetor run dry before putting it away, it does not smell of gas with the fuel vent and fuel valve both closed. The maker advocates storing in a nicely ventilated area or garage, but odor from fumes is not a issue.
3) It really is also beneficial at property through power outages. I have a larger much louder 5500w contractors generator that plugs into a 12-circuit transfer switch wired by an electrician, but as a courtesy to neighbors I shut that off overnight. I can use this Yamaha unit with an extension cord to maintain just the refrigerator running overnight and it stays in 'eco mode' so it practically purrs. Also the fuel burn rate is highly low so it uses a fraction of what the bigger generator would use.
Have had zero challenges with this unit so far.
This generator is super quiet and the engine runs truly smoothly. It instantaneously adjustments it's operating speed just as fast as I can move the speed switch on a 1850 watt hair dryer I applied to test it. It doesn't involve oil and the angle of the oil fill hole is practically horizontal, producing it a small troublesome to fill even with a funnel, but they did put a nice tiny drip tray perfect below the opening so it doesn't go everywhere. The gas gauge is certainly good. Produced in Japan. Their competitor (Honda) has some nice videos on their website demonstrating the sound level of actual generators running and the equivalent size Honda generator is rather close in noise level to this a single. Yamaha should really do the exact same but until then, check out the Honda webpage.
Yamaha says this is CARB compliant on their website so I'm not certain why Amazon says it isn't. The label on the generator says it is a three on the 10 point California emission scale. Yamaha just isn't creating a massive deal of it like some other individuals do I suppose. This is a new model as of summer 2009. The starter cord is genuinely very easy to pull - as opposed to any other engine I've ever started by hand.
