Default Motorized Cooler Cart: Gas or Electric

I finally have some time for a project and have a great idea. I am going to build a cooler cart.

Im not sure if i want to use a 7hp tecumseh or a razor e-100 motor.

If i were to use the 7hp it would be mounted outside of the cooler, on the back.
The electric motor i would mount on the inside of the cooler.

The e-100 scooter i have has already been modified and currently runs off of 48 volts.

I am leaning towards using the engine, for the raw power and torque.

I have hills around were i live and will probably drive the cooler to the grocery store once its done.

Future plans involve a cooler trailer...

I have plenty of materials and supplies to build whatever, but id like to keep it basic (belt or chain) so I am open to suggestions...

So, should I build a beefy, fast gas powered cooler, or an electric cooler?

i would look into 4WD, a full cooler, you, running gear, could be a lot of weight. electric would have the power, but on the whole inefficient.

Your right mike, Even the modified e-100 motor wouldnt pull me plus a full cooler .

Im going to go for a trike design.

What gear ratio would be best for this engine? Im looking for speed (20-25+ MPH?), but also enough torque to pull a heavy load( Me,A full cooler, and possibly a full cooler trailer-about 200-300 LBS total) I will sacrifice some torque for more speed if needed,but not a lot.

I found a video of a motor cooler, It looks like the engines inside the cooler? Is that at all possible due to air circulation?

the engine would get really hot. and if you put the engine in there you warm up your beer.

gearing will depend mainly on engine rpm. i have a pretty light frame with a 6.5hf and single wheel drive. my engine is not on par and only does 22 max. nominal rpm is 5500 +/- 300. 6:1 is what most guys run, if there's enough torque ~30mph roughly. with that weight i would try 6:1 to 8:1. make sure the fluid level is high enough not to slosh. things could get hairy quick. i would run live axle. and i would try a cvt/auto tranny. it will help alot.

You would have to cut vents into the cooler so the engine would get enough air, but whats the point of a cooler kart if the cooler is full of engine and not beer?

Thank you for pointing that out, i dont know what i was thinkin!

I would like to put the engine in the cooler for the looks, if you have a suggestion on how to do that let me know.

Now that that is said, warm beer is NOT acceptable for the cooler cart! there would be no point in having the cooler cart if the problem isnt solved.

If the engine is in the cooler, the cooler cart will have a cooler trailer (maybe 2) for cold beer Problem solved!

Or, just extend the cooler a little with some sheetmetal for the engine, just make sure you have vents to let fresh air in.

How much air flow would an engine of this size need? Its originally from a snow blower, would it have a lower overheating point than an engine from a warm weather machine?

if you have now decided to put the engine in the cooler, you could partiton the cooler. one compartment for beer, one for engine. on the sides of the cooler make louvers to allow air in, and remove the back or make bigger louvers to allow the air out.

The engine will be enclosed whether i put it in the cooler or in a sheet metal box. An air scoop might look good... A fan isnt a bad idea, i was planning on mounting a motorcycle battery on it anyways.

How about a small electric motor at each of the 4 wheels. My
kid's gator has a motor at each wheel no bigger than my drill
motor.
