Looks good - let's hope I don't need it.

In one year our area had two major multi-day power outages. I purchased this generator after speaking with licensed electricians and reading on-line reviews. Set up was very easy and clear. I wanted to run a test with just a small amount of gasoline (1 qt) but I needed a gallon to get everything flowing. It started and I ran it for about 20 minutes - testing electrical capacity. Seems good - let's I hope I don't need it, but if I do, it's there and I'm confident it will get the job done.

Great Features and Value, but lacking in Documentation

I really think you did a good job designing this product. The Maintenance will be quite easy based on how it;s designed. I really like that the Oil Filter, & Air Filters are VERY EASY to access. Changing Oil with the attached discharge hose will be Easy & Clean. That being said, I really don't understand what you provide such useless Documentation. The assembly details are so Tiny I had to use a Mangnifier to be able to see them. Additionally the Hardware defined in many locations was not the Hardware required. It's really no n=more expensive to provide GOOD Documentation than it is to provide Poor Documentation. Additionally, I was missing Hardware, and had other Hardware that was not used. The instructions are Vague & unclear for anyone who has not assembled oner of these already. That part really needs to be rewriten!

Just what i expected!

I always do a major investigation before i purchase anything expensive.Sometimes it takes me weeks.I read everything including reviews.Finally after days of asking questions and reading many reviews i felt the Genarac GP6500 was right for me.I was right.Assembly was easy and took about 15 mins.Filled it with the oil that was provided and it started in two pulls.The unit was powerful enough to power up my whole house except the clothes dryer and electric oven.No more freezing in the winter or sitting in the dark.It is relativley quit and ran about 10 hrs on a tank of gas.I am very satisfied with my purchase and you can't beat the quality of Genarac.

No Alternator but great power

This generator has great power runs well when it's on but every day you have to jump start it because there isn't a alternator that charges the battery when it's on. It's a hassle trying to always make sure the battery has enough juice to start the generator. If not your out of luck.

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.

Association said no Propane

I checked with my HOA, they said no to Propane back up. So after researching what my needs were and knowing the quality of Generac. I purchased a GP17500 after talking with a Generac consultant I knew this would run my whole house. Live in Florida known for Hurricanes,I am worry free in the event power goes down.

Great unit with Excellent customer support

bought this unit, and had a major issue with it before it even had any hours on. I contacted customer support and had the issue resolved with one phone call. They sent out the parts right away, without any problems. now the unit runs perfectly. very happy with this purchase.

Hurricane Dorian

Purchased this unit just prior to hurricane hitting Nova Scotia. We lost power for three and a half days. This unit kept all the essentials running and kept us safe and dry. Didn't run it over night, but pretty much all of the waking hours and only had to refill the fuel tank once. No super heavy loads but it handled the refrigerator with no problems. Used it for coffee, microwave, induction cooktop, TV and internet. Delighted with the unit.

Purchased in 2014

I live in North Georgia, we have ice storms and snow storms and tornadoes, even tropical storms that knock out our power from time to time. My house was prewired for a generator and has a transfer box. This unit was pretty much a plug and play situation. It easily runs the heart of the house more then adequately. For the last 3 years we have had to use it for every year for anywhere from 4_days to 2 weeks and we ran it 24/7. Other then changing the oil and replacing the starter battery, its been maintenance free. I heartily recommend this unit to anyone that needs a generator.

GREAT BUY!

I'm a dealer/ electrician in Massachusetts and honestly have had no problems with any of the (10) 6500w/e that i have received in the last few months. They are easy to assemble, start easily and with the large capacity tanks, they run all day long. I also like the free battery charger and built in jack. Great product!
