Over 700 miles and the smell is bad. The new is gone, it is exhaust smell. When Dad pulls it in the garage it stinks the entire garage. Going back for the 4th time tomorrow.

The gas fumes come up thru the engine compartment because there is no tail pipe. You will need to fabricate an extended exhaust pipe or you could try placing heavy duty weather strip between the seat and engine compartment.
Here is a diagram of the muffler:

Yikes, that does not sound very good for someone who scored 15 out of 100 on a mechanical reasoning aptitude test. Give me something to write and I can pull it off 100%. Fixing exhaust systems by a diagram...you got to be kidding!!! So what are people going to do who are like me? Is this a major problem with this new model? How come more people are not complaining? Just trying to understand.

Wow, sounds to me like the bottom of the exhaust unit maybe isn't properly fit to the panel under the engine compartment. We have no exhaust smell at all. Way less than our Efi with the extended tailpipe.
There was the horrible stink and smoke until the varnish burned off, but that didn't take long - maybe 200 miles at most. When ours was brand new you could tip the seat up and see the stinking smoke rising from the exhaust assembly -- but that didn't last. Happy now, so hope for you.

This past Tuesday I went to C&C and while there I got to test drive a new 2017 Yamaha.
The one I drove had a hard enclosure, I drove it with the doors open and closed
and I didn't notice any bad exhaust smell in either case.
Now I think the test vehicle had been driven often before
I drove it, which might have burned off any manufacturing coating on the muffler.
The ride and sound are much improved.

It really is quiet, for a gas cart. I was impressed.
I noticed the varnish smell, which the dealer says will burn off after 100-200 miles or before.
But no smell from actual gas fumes.

Dec. notes on service order stated "glass fibers inside exhaust came loose and wasn't catching carbon. Reattached and no more fumes are being released." I love the cart, just wish they could get this straight. This is all new and there are sure to be some things to work out.

Hi, just a friendly reply. We have a new EZ Go, we love it, quiet dependable. If everything else was the same, then consider this,,,,,,,,,,,,,,,, We do not burn gas, do you know that when you burn one pound, one pint of gas in an internal combustion engine,,,,,,,,,,,,,, it takes 14 pounds of air. So,,,,,,,,,,,,,,, 15 pounds of exhaust are shot out into the surroundings. Have you noticed the garbage you are breathing in the tunnels,,,,,,,,,,,, IT IS THERE FOLKS. We also have the auto water filling system for the batteries, so easy. A local independent cart mechanic was nearby and I asked him about the electric annual checkup he said there is almost nothing to do on it.
Have you seen the huge line of carts at local cart shop in there for maintenance? Have you seen the gas pump. Two years ago, I was shopping for my electric cart, they almost refused to talk to me,,,,,,,,,,,,,, they sell gas.
Sorry, my background is Engineering and Combustion,,,,,,,,,, well you could not give me a gas cart and I mean that.
Sorry for being so blunt, but I think you wanted an opinion so that is what you get for asking a Polish Engineer with combustion background.

bbbbbb :coolsmiley:

From bbbbbb. Where is the comment that anyone despises anything??????

Please. Let it be factual folks.

Regarding electric, SECO says with my charger, it costs 15 to 19 cents an hour to charge cart in the garage. If we run the gauge down to a bit over half full,, that means we do the rec centers (4) , two movies and three trips to the stores. For those of you who are from Rio Linda the gauge will be a little bit above the one half mark. That is about it for the week. Then at home it takes abut 4 hours or less to charge, so try to get your math polished up, that means about 60 to 76 cents. An earlier poster said he is considering electric, that is a fact.
Here is a small addition from an older Combustion person: To burn one pint, about one pound of gas in an internal combustion engine.......... (IF the engine is perfectly tuned and a lot of them are not) it takes 14 pounds of air. So 15 pounds of exhaust are going out the exhaust pipe. While going through the tunnels, a lot of it is there, try not to breathe those products, just a suggestion. last time I checked my cart does not have an exhaust pipe, I am glad to see that.

The electric v gas cart controversy has been ongoing for the 10 years that I have lived here. when we first move here the vast majority of golf carts were electric. As The villages expanded the number of gas carts increased. After 9 years I gave in and purchased an Yahama EFI because of one reason only, distance anxiety.

I ignore the 'gas smell issue and wonder how many people who defend electric carts based on environmental reasons don't also drive full electric cars.

It seems this thread was about Yamaha 2017 EFI gas carts.
How did it get railroaded?

Guess I'm late to the dance but here are my thoughts: I have a 2017 gas Yamaha cart. I have nearly 2000 miles on it and have never had any smell whatsoever. My wife has an electric cart but always rides with me when we are together. She has an acute sense of smell and has never noticed an odor either. Both she and I love the 2017 over the 2014 that I had before. My '17 is much quieter, the ride is vastly improved, the turn signal lights (inside the cab for ease of seeing) and the C&C windshield are four of my most favorite things about my cart. To repeat: perhaps I'm unusually fortunate but a smell is not a part of my world.

Like your wife, I also have an acute sense of smell, so I appreciate your comments.

I'm only guessing that there must be some kind of a problem that they're having trouble diagnosing. I really feel sorry for them but don't you not buy a product because one other person had a problem.
