Product Details

There is no better upgrade than the EZGO Marathon High-Speed Motor-Controller Kit. We have several on the shelf that would be compatible with your Marathon since your eye gravitated right to the go-fast department. We can't blame you; we firmly believe the need for speed lives in us all. We were tired of seeing all these kits for the newer golf carts and no love for the vintage models. Thus the Marathon performance package was born. Now we can take that antique and make it a sleeper like no other. The first time you pull up on a brand new EZGO and blow his doors off, he's going to be trailing you till you decide to stop and tell him where you got the stuff to make your golf cart fly.

With the high-Speed conversion kit, you will get a six-horsepower motor and a 500 amp controller. You will also get a weld cable set that comes in four-gauge and a heavy-duty solenoid. You may want to also consider upgrading your forward reverse switch with a heavier one as well. Give us a call here at Buggies Unlimited, and we will get you set up right.

  • 36 volt E-Z-GO Marathon 1989-1994 (Lever style F/R switch)

From racing Barbie Powerwheels, to smoking Go Carts!!
Are you tired of getting beat by little kids and their 3mph power wheels? Get this kit, install it and hang on. Went from 10-12mph down hill with a tail wind, to a solid 25mph (GPS verified) flat land speed runner. I now tailgate cars and push them outa the way on the neighborhood streets. I own this place now. My golf cart is the the talk of the neighborhood. If you want to feel the power and get all chick's, get this kit. You won't regret it!

Perfect fit & impressive speed!
Seems to be really good, however, I need new batteries to really put it to the test.

I have a 1997 ezgo golf cart 36V. This cart has no lift and 17" wheels. Would like to upgrade to a higher torque and speed motor and controller. What can you offer? Thanks.....Jerry

33013 is going to give you the maximum torque! Even though ts recommended for lifted cars, this kit will work great for a non-lifted, it will just produce more torque! We have several customers that install the 33013 on stock golf carts and then use it to pull their boat or camper or work trailer! The possibilities are endless!

What is the reason this cant be used for lifted carts? i have 4in lift with 22in tires. 1994 marathon 36v.

I put this conversion kit in my '93 EZ GO Marathon 36v cart (not lifted). It is not recommended in a lifted cart because it really increases (almost doubles) the speed! In a lifted cart, with that much speed, you have a high risk of rollover. That's the danger & why it's NOT recommended.

I have a gas powered tub sideby side. I would like to make this into an electric vehicle and was wondering if one of your kits would wood for this. It would be nice if we could get it go 40-50mph 
Bob Allen thanks ?

Hello, with the right setup, almost anything could be done. You would need to have enough power to support the size of the side by side. But this would be a full custom build and would require a full electrical system based on a factory harness, so that's where you would need to start.

I have a 1987 Ezgo marathon electric will your high torque 1989 system fit mine?

Only if you have a controller in your cart now, and not the resistor coils.

I have a 1989 EZGO Marathon with 4" lift and 22" tires. Can i use this kit for that setup? Also, what type of fabrication will need to be done for mounting?

I have 91 Marathon with a 3” lift and 20” tires and have had the kit installed for over a year and a half with no issues. There are no modifications needed to mount the kit.

Will this be ok on a lifted marathon with 22” tires?

I have a '91 Marathon with a 3" lift (planning on going to 6") and 20" tires and it works with no issues. You will need to realize that it will be more prone to tipping then a standard height cart though.
