Looking at upgrading to a TXT shuttle 6

[DFW Rusty]

Local golf cart dealer sells TXT shuttle 6, lifted, 22" tires.

I am having trouble getting ahold of this guy and my wife and I are supposed to go by there Friday and look at them and test drive one. I have been trying to google info on these all day and cant find much about what engine is in these.

I was hoping to get an Express L6, but we are paying cash right now and this fits our bill better.

Questions-

What engine is in these?

Is the engine reliable, does it have any known issues?

What should I expect the top speed to be, the only info I found is average speed is 19mph.

Any way to squeeze more out of the engine without taking away from the reliability of it? We plan to take this to the beach about 3 times a year and cruise dirt roads around my house and I really need it to be able to go about 20+ MPH to cruise the roads at Port Aransas.

Below is a pic of one of the units we are going to look at Friday.

I don't have an answer for you, but I do have a Sail boat in Port Aransas, and I just love that town, and the people. It is a small drinking town, with a fishing problem.

We decided to pass on the txt shuttle 6 for now. The ones he has were kinda slow. My phone gps clocked us at 18.5 mph on flat road. My wife and I agreed that if were going to get a new cart we want an express beach buggy.....

However, we are starting to lean towards a Polaris ranger. I was told by a buddy that supposedly beaches in Texas are starting to allow sxs on the beach now.
