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 A$2,400.00.

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.

Great product


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 A$600.00.

not as good as I'd expect for a Jap machine


This is the second EF2400is Ive had. The first one after three years, the ECU failed. It was always an easy machine to start, usually first pull, but anyway I decided to stay with the brand...bought another one....and again the ECU failed..!!...after a few years..
Before the Yamaha I had a Honda...not once did i have a problem with it. It always started first time, and not once did it ever let me down. ...Im going back to Honda. You might be ranting how good your Yamaha is now.....but it will stop working sooner or later.....Honda's seem to go on for ever..!!

Purchased in August 2015 for A$2,200.00.

Not happy


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 A$2,000.00.

Excellent generator


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.

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.

EF2400IS - Great Geni


This generator is great. Quiet and efficient and starts real easerly. We bought this unit after researcing and comparing against the 20i Honda. i found that overall the Yamaha came out on top. If there was one thing i think the Honda had on this unit, it would be the ease of moving it.
Very low noise. Ease of operation.
Hard to move one out.

Questions & Answers

Richie Lasked

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.

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?

1 answer

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.

Thanks Rob
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?
