The best all-round generator available
The Yamaha EF2400is is the best and most functional generator available to RV operators in Australia. It is powerful, quiet and fuel efficient while continuously outputting 2000 watt sine inverter.
Purchased at Pitmans Motor Cycles, 420 Main North Road Blair Athol SA 5084 for $2,000.
This has only done 320 hours work. Started playing up going straight into overload and uprevving. Any service centres were to the point of non existent that could look at it to diagnose problem. Eventually found someone not entwined with Yamaha, turns out the inverter is the problem, would cost as much to repair it as buy a new one, and take 8 weeks to be able to get one.
The irony was I replaced a working cheapie with this because I thought it'd serve me better. I'll be binning this and going Honda. Biggest disappointing purchase in my life thus far. Do not go there. I just went to a shop to get a new one and he said they're so bad he won't sell them anymore and has pallet loads out the back with the same problems.

Great unit, reliable and economical.
I have had one of these for a couple of years now, and haven't really had a good chance to use it in anger during an extended outage or prolonged camping trip. It has seen a fair amount of duty in terms of providing lighting and running the odd fridge or freezer, and frankly I couldn't be happier with this unit.
I have to admit I picked mine up VERY cheap due to a run-out sale, so I'm probably a bit less critical than somebody who paid full whack for one of these.
It's very easy to get started with the recoil pull system (I hate the idea of ...battery-electric start, just another battery to die when you really need it) and it's pretty quiet even when loaded up. Power generated is very clean; I have seen some cheaper generators which advertise "pure sinewave" output struggle with powering battery chargers, anything motorised and LED lighting without flickering, all of which are only a challenge if your generator's output is modified sinewave or otherwise poor. No such issues here. Also, this generator is pretty frugal on petrol too, whether it's loaded up or not. Overall, a great generator. Yamaha has outdone itself with this one, and it's easily a match for the more expensive Honda competition.

Rubbish...I've had two...both with the same problem!
I bought my first one new. I wanted quality and thought that's what I was buying because its a Yamaha...right!! It wasn't too long before the Electronic Control Unit decided to quit, and that was the end of that, because they cannot be repaired because its encased in resin!!!
Stupidly I bought the same model second hand.....and the same thing happened again...rendering both units useless and worthless. I'[m now $$$$$ out of pocket...a bit of a slow learner!!
And to think I have a Honda 1kw 30 years old in my shed that has never let me down......

Great until it needs fixing.
Have had this unit for about 8 years with very little run time during that period. Due to corrosion I found I needed a new carburettor. Quoted 2 prices $600 and $800 Australian. The unit is only worth $2100 brand new. A Honda carburettor is $60. You do the math.
Purchased in January 2012 at Not sure for $2,400.
perfect back up generator for home.
purchased this generator as a back for home we often loose power in our area it can run the ducted heating & fridge at the same time easily, can run our 2400w electric kettle hair dryer toaster oven coffee machine washing machine dryer etc but not all at the same time have hooked up to a switched power board so just turn off one appliance & turn on what u need also very easy to service.

Off Grid Saviour
Have had this generator for 3 years as my alternative power source when free camping in our 22' caravan. We have been on the road for the past 5 years and have other generators to compare to.
Apart from regular servicing, which is really an oil change and air filter clean, i have not had a single problem with this generator. Has been used in the recent heatwave to run the air con on our van which it does with no problems. Has run continuously for 10 hrs (apart from stoppages to refuel) with faultless service.
Starts first pull everytime and...is reasonably quiet for a larger generator. Comparable to the similar sized honda. Currently has 258 hours of use. I have fitted an hour meter to monitor use for servicing purposes. I have no hesitation in recommending this generator.
Purchased in September 2015 for $1,899.
Awesome product. Very reliable and easy to use. Good size to transport on site or around the farm. Much better quality than the Chinese imports. It’s also a very quiet machine which is great
Purchased in April 2019 at Pickles Auctions for $600.
Have had for 7 years and use as little as 70 hours a year. Have had to pay to replace ecu at just over 5 years old and 2 years later the unit smoked and now requires further repairs. Always serviced correctly since new.
Purchased in October 2012 at Generator Store for $2,000.
I tested my caravan AC (older Ibis) on both Honda and Yamaha 2 generators. No go. Bought a cheapy 4.4kw - what a mistake, it would not power anything over 1600w. Bought the Yamaha iS 2400 and have not looked back. Runs AC, washing machine (300w) and battery charger (240w) at the same time. No Eco switch needed - it's in full time Eco as the oversized engine (171cc) has enough grunt to power up under full load. a bit heavy at 32kg, but that's not surprising with the large, easy-working engine. Starts easy, and I like the fuel gauge, so I can refill when it suits me.
Starts first time every time.
I bought my generator back in December from Totals tools and I have set it up on a fridge slide in the ute canopy. We are basically full time travellers and I have been using this genny in conjunction with the gas cooking to boil the kettle, cook toast and use the frying pan. In the 3 months we have owned it we have not had any issues with it. The main reason we bought it was to run the aircon which we haven't had to yet but we won't have a problem as it runs all the other appliances with ease. A bit heavy but on the fridge slide I don't have to man handle it. Runs super quiet as well.
The perfect Builders tool.
I have just finished a 650 sqm 2 storey home to lock up stage using only the Yamaha 2400 as my power supply. Permanent power is now connected and the money saved installing temp power almost paid for the inverter. Simply brilliant and a must have tool for remote building.
Perfect caravan genny!
Weighed up the options for a long time for home backup power and for our caravan and ended up with 2 prefered options. The Honda EU20i and the Yamy EF2400is. Decided on the Yamy for a few reasons. Extra power, fuel gauge and fuel tap. Our air cond is an old AirCommand Wren....no soft start...genny roars a bit on start up but purrs 5 seconds later. AirCommand weren't confident the honda EU20i would handle the hard start and that decided it for me. Yammy is heavier and bulkier but is a powerful unit. As far as the noise goes there is no such thi...ng as a quiet genny. Ive heard both units and they are bearable 10m away. Better 25m away or further but long leads arent a good idea either. You get used to the constant hum. I would be surprised if there is a caravan aircond the yammy couldn't handle. Definately recommend the Yammy EF2400is!
Very quiet and plenty of power
I needed to upgrade from my current generator a Honda eu10i as I've changed from camping to caravaning. So I did the compare the pair, on one hand the Honda eu20i & on the other the Yamaha ef2400is.
The Honda eu20i would have been the same as the eu10i in quality and a great unit, The Yamaha seem to have the extra punch alowing for the reducution in power output in hotter/colder climate or altitude.
I've owned a 4stroke Yamaha outboard engine for 9 years and I'm absolutely impressed with the finish, fuel efficiency & decibels, so I sold my ...
Excellent product, easy to start, and ultra reliable
I bought this genny tossing up between the Honda 2kw.
Was used to power the aircon in my caravan. But, unlike some competitors, I could run the Microwave AND aircon simultaneously!
It starts easily, runs a hell of a long time on a tank of fuel, and would be perfect for caravans where you have the room, especially larger vans
It's only fault is size and weight. It's big, heavy, and cumbersome. I could slog it around myself, but it's really a 2 person lift, and not something you'd want to toss around a camp sight without need.
Otherwise, if you were looking for a home backup genny, or one fixed into a larger van, it was bulletproof.
Quality Yamaha engineering, would gladly recommend to anyone.
Questions & Answers
Does turning the EF2400is upside down to drain fuel and retrieve an item accidentally dropped into fuel tank do any permanent damage ?
It has fresh fuel , oil and new spark plug but won't run . Has started but stops after a few seconds.
Did you find out? I just dropped something small in the tank and cant get it out and am hesitating to turn it upside down.
Never heard from any1 until now .
Probably over 12 months since I posted it .
I gave up on mine for now as we moved house cupla times .
I spoke to a lawn mowers mechanic, said it would just be oil blocking carby , he reckons all he does to 4 strokes is carry cleaner until they run .
How small is the thing you dropped in ?
My Stator has gone on my EF2400IS. I need to buy the part but from what i can se they are way to expensive. Do i have to buy genuine?
Mine went as well Ian and I ended up buying a new generator (same one). mine was 8 years old so for $1900 I just started again with a new one. What is the price to repair yours with genuine parts?
Would this generator be a good back up generator to an off grid solar system? Can it be wired in for automatic start? Does it have an RCD?
Roz, the Yamaha is2400 does not have electric start. It's a very reliable pull cord start. And it does not have an inbuilt RCD as far as I know. As a camping/caravan power unit, the RCD is inside the caravan. It would certainly make a good backup to a solar/battery off grid system. On a 48v system it could power a 40 amp 48v charger.
What about using it for charging batteries and using for powertools whilst building a house in a remote location? Will this sort of use damage the generator?

- This Yamaha generator features a max power rating of 2400 watts, or 2.4kW, and a rated output of 2000 watts, or 2kW. This is an expected and reasonable amount of power for a small portable inverter generator.
- A generous 6-litre fuel capacity allows this generator to operate for 9 hours on Eco mode, providing you're running at a quarter of the power load.
- A ‘smart throttle’ feature adjusts engine speed based on power load to maximise use of fuel and keep noise at a minimum level.
- At a quarter load, this generator operates at a noise level of 54dBA at 7 metres away, which is equivalent to the hum of a household fridge. At full load, it runs at a volume of 59dB, comparable to a conversation in a restaurant.
- The handles on either side of the generator make it easier to transport and carry.
