Ready!

I found the unit to be well made. As big as it was, it is easier to move than I thought it would be. Well balanced. All features are well marked. I purchased the unit for power outage during severe weather. This unit replaces a smaller unit that could not handle all of our needs. The investment will be worth it when we lose power again out here in the country.

Powers almost whole house!

I researched a host of generators before deciding on the Generac GP6500. For me the Generac brand was the deciding factor and the GP6500 was the largest wattage I could fit into my budget. It was shipped promptly and arrived without so much as a scratch on the box. Assembly was quick and easy. Had a transfer switch(6 breaker) installed and everything in the house is usable except central air and washer and dryer. The generator started up on second pull and roared like a lion but powered everything I wanted it to power with room for more. I couldn't be happier. Almost looking forward to the next power outtage because I am ready for it now. I have not seen anything on this generator that is not well built and ready to last for a long time.

Very Impressed - A well manufactured machine

I just purchased the GP17500E, Assembly was straight forward (A 2 man job). The over all design of the generator was well thought out, such as the oil fill area is large enough to fill directly, no funnel needed, also the oil drain is a hose, just unscrew the cap and you are draining the oil, couldn't be easier. Customer Support was very knowledgeable and get this, open 24hrs 7 days a week, I thought my company only did that.. If you order on line just be aware on the shipping method, Box Truck means a 52 foot semi trailer which was to heavy to go up your drive way, I grabbed my neighbor who had a pickup truck, unloaded on to the pick up and brought to the house. It all worked out. The generator started right up.

Quality machine

After a 3 day outage this summer, I upgraded from a 5000 watt generator to the 6500 watt Generac and installed a larger transfer switch so I could power more items during our frequent power outages. The machine is obviously well built. It has a small footprint and it's easy to move and started on the first pull. Based on other reviews I thought it might be a little noisy. But it actually seems quieter than my old one.

This Unit is Fantastic!

I originally purchased the GP5500 unit, but traded it in for this GP7500E. The electric start is prefect. I set up the unit in no time and I had my wife come down to start it for the first time. She simply pushed the start button and it fired up. It actually runs quieter than other generators in the neighborhood. I would derfinitely recommend this unit to anyone, and I have. You can't beat the features for the price.

First Impession not good, Sence then perfect

Bought this generator as a home back up. First use was a long term power outage in cold weather. After 17 hours it pushed the little gasket/bushing out of a fitting where the two wires go through the crank case for the low oil sensor, It puked all the oil out of it on my driveway until the low oil sensor shut it off. Not good at 2am in 5 degree weather. In the dark I thought it blew up with all the oil. Diagnosed it the next day, pushed the bushing back in place with silicone sealant. Sense then it's been perfect. I like the generator now but at 2am the first use I was frustrated. I would still recommend this generator as I think this was a fluke and it's been perfect since

Easy to use, reasonably priced, Gets the job done nicely!

I already had to use my generator, because the local substation near us was shut down for about eight hours. had it up and running in about 15 minutes and ran 80-90% of the house without interuptions. Very pleased with this generator! I would highly recommend this generator!

Do your research and then buy this one.

I had purchased a Westinghouse Generator and it had all kinds of issues. Before I took it back I did finely get it to run. I don't know who makes there motor but it just sounded very cheep, loose and claney took it back Fast forward I decided after researching several other top notch units I decided on this Generac GP8000e. I was missing things not in the main box but the place I bought it from supplied it all so all was good. I connected the battery, it was charged up, added the oil added mid grade gas, turned on the gas flow to the carb and it started right up and this motor is tight and sounds like a top notch motor. My only regret would be the tool kit that Ace gave me was the cheapest 2 wrench's I think I have ever seen in my life and I don't think they are relevant to anything. i was also missing oil and they gave me Pennzoil and not Generac oil and I heard Generac is the best. Buy it you you wont be disappointed!!!

Unstoppable

Purchased about 4 years ago During power outages and I get a lot as I live in remote area I run my A/C 3 deep freezers. And 3 frigerator freezers also my well. Plus lights and power equipment if I'm in wood shop Quite the machine I know gas tank will run at least 14 hours I never shut off just refill with gas as it doesn't splash out with the filler screen Definitely worth it

It has what the average household needs.

Only time will tell if it holds up well over the long haul, or if the investment was a poor decision. Realistically I don't believe it is meant for heavy duty service, but if taken good care of, and with only emergency duty, I will expect a long service life (many years) of reliable service.
