90 marathon, Predator 670, & club car transaxle
Hello everyone, I'm new to this golf cart stuff & could use some help. I've got a 90 marathon gasser, in the process of picking up a new predator 670, then I purchased a 94 club car transaxle. Will there be a chance this is all doable with the parts I've acquired? I've also ordered a true comet 780 clutch & a comet 214010a driven clutch, for the 1-3/16" belt. I would love to hear some thoughts on this. Btw I got a new honda gx390 too if that might be a better option. Thanks everyone & hope to hear some thoughts. Forgot to mention I got a 4" lift kit to install a little mash up of different years & models, but should all bolt in.

Re: 90 marathon, Predator 670, & club car transaxle
Also a quick note about me. I'm a certified automotive/diesel technician for 25+years. I've got a welder & plasma cutter & access to a lathe & mill. I've built about every type of ride on toy in my life I guy could think of, except a golf cart. So I'm up for the task, I think?

You might want to look around Vegascarts site at the installation manuals for some ideas for direction in your project. They do both 670 and 390-460 installations in many different carts.

Re: 90 marathon, Predator 670, & club car transaxle
With your skills you should be able to make it work. The transaxle will need a mounting fabricated as well as suspension. I vote for a 4 link
There's no comparision between the GX390 vs the Predator 670. The 390 is like 13/15 hp and the 670 is 22 hp, both rated around 3600-4000 rpm. If you put a rev kit and cam in either they will spool up past 5000 and have lots more of top end power, prob in the neighborhood of 18hp and 25hp respectively. I've had a 420 clone engine, a 440, and a built 460 clone and they run good, are compact and fit well into most carts without much modification, but they are a little chattery and have vibration. The 670 has WAAAYYY more power, is super smooth, and is not super loud with the muffler it comes with, but will likely need a dropped mounting and/or a lift kit to get it to fit, but worth the cost and effort IMO. If you have the means and budget, go with the 670, you won't regret it. |

Re: 90 marathon, Predator 670, & club car transaxle
If you want the best ride and handling lift kit get the Jakes LT kit. With a welder and skills you can make anything fit really, just takes time and tools etc. They're expensive but well worth the cost if you have the money to spend. The best handling cart I built had a sport ATV front end on it, cut it off of a Yamaha Warrior atv and used the hydraulic brakes etc. Used atv wheels and tires. It was a great handling cart. I've also used the Jakes LT kits on a few carts with excellent results, but nothing like the atv front end.
Oh, 94 club car? Is that the CCW rotation transaxle or the CW rotation? If it's CCW the engines you listed will work fine. If it's CW rotation you'll actually be using reverse for forward, yeah backwards, so gearing is low. I don't know club cars so you'll have to check into that. |
