Converting an electric golf cart to gas is possible but requires replacing the entire drivetrain, not just swapping one fuel source for another

An electric golf cart runs on a battery pack and electric motor. A gas golf cart runs on an internal combustion engine, fuel tank, and carburetor or fuel injection system. These are fundamentally different powertrains. Converting one to the other means removing the battery, motor, and controller, then installing an engine, transmission, fuel system, and exhaust system in their place.

The conversion is technically feasible because golf cart frames are straightforward and modular, but it is labor-intensive and expensive. Most people find it cheaper to buy a used gas cart outright than to convert an electric one. The conversion also voids any remaining warranty on the original cart and may affect its resale value.

Key Takeaways

  • A full conversion requires removing the electric motor, battery pack, and controller, then installing an engine, fuel tank, carburetor, and exhaust system.
  • Conversion kits exist for some popular models like Club Car and EZGO, but they are expensive and require mechanical skill to install correctly.
  • You will need to handle disposal of the battery pack responsibly, as lead-acid batteries contain hazardous materials and cannot go in regular trash.
  • The total cost of parts, labor, and disposal often exceeds the price of buying a used gas cart in working condition.
  • After conversion, your cart may not meet local emissions or noise regulations if you plan to use it on public roads.

What parts you need to remove and install

Removing the electric system means taking out the battery pack (usually four to six lead-acid batteries weighing 60 to 100 pounds each), the electric motor bolted to the frame, and the motor controller that regulates power. These parts are wired together and mounted in specific locations on the chassis.

Installing the gas system means adding a small internal combustion engine (typically 200 to 400 cubic centimeters), a fuel tank, a carburetor or fuel injection system, an exhaust pipe with muffler, and an ignition system with spark plugs. The engine must be mounted securely to the frame, aligned with the existing transmission or a new one, and connected to the fuel and exhaust lines. You will also need to install a new battery for the ignition system, which is separate from the old traction batteries.

Some conversions use a direct bolt-on approach if a kit is available for your cart model. Others require custom fabrication of engine mounts, fuel line routing, and exhaust placement. The more custom work required, the higher the labor cost and the greater the risk of poor fit or performance issues.

Conversion kits and where to find them

Conversion kits are sold by aftermarket suppliers for popular golf cart models, particularly Club Car DS and EZGO TXT carts. A kit typically includes the engine, carburetor, fuel tank, exhaust system, engine mounts, and hardware needed to bolt everything together. Kits do not usually include labor or specialized tools.

Suppliers like TrailerTec, Bintelli, and other golf cart parts vendors sell these kits online or through local dealers. Prices range widely depending on engine size and quality, but expect to pay $1,500 to $3,500 for the kit alone. Installation labor, if you hire a mechanic, can add another $1,000 to $3,000 or more if custom work is needed.

Before buying a kit, verify that it is designed for your exact cart model and year. A kit for a Club Car DS will not fit a Club Car Precedent, and a kit for an EZGO TXT will not fit an EZGO RXV. Mismatched kits lead to poor fitment, performance problems, and wasted money.

Battery disposal and environmental responsibility

Golf cart batteries are lead-acid batteries, the same type used in cars. They contain lead and sulfuric acid, both hazardous materials. Dumping them in the trash is illegal in most places and harmful to the environment. They must be recycled or disposed of through a licensed facility.

When you remove the battery pack, contact a local battery recycler, auto parts store, or hazardous waste facility to arrange pickup or drop-off. Many retailers like Advance Auto Parts and AutoZone accept old batteries for recycling, sometimes offering a small credit if you buy a replacement battery from them. Some recyclers charge a small fee for disposal if you are not buying a new battery. Call ahead to confirm what they accept and what the process costs.

Cost comparison: conversion versus buying used

A conversion kit costs $1,500 to $3,500. Labor to install it ranges from $1,000 to $3,000 or more. Battery disposal adds $50 to $150. Miscellaneous parts, fasteners, and adjustments add another $200 to $500. Total cost is typically $2,750 to $7,150.

A used gas golf cart in working condition can often be found for $2,000 to $5,000 depending on age, mileage, and condition. You avoid the conversion labor, the risk of installation errors, and the hassle of battery disposal. A used cart also comes with an established history and known performance, whereas a converted cart is essentially an experiment.

The conversion makes financial sense only if you have a specific attachment to your current cart, access to free or very cheap labor, or a need for a custom setup that used carts do not offer. For most owners, buying used is the simpler and cheaper path.

Mechanical skill required and common installation mistakes

A conversion is not a weekend project for someone without mechanical experience. It requires removing and installing engine components, routing fuel and exhaust lines safely, securing the engine to the frame without vibration or misalignment, and testing the ignition and fuel systems. Mistakes can result in fuel leaks, exhaust fumes inside the cab, poor engine performance, or fire risk.

Common errors include mounting the engine off-center, causing vibration and frame stress; routing fuel lines too close to the exhaust, risking fuel vapor ignition; failing to find the fuel tank properly, causing it to shift during turns; and not grounding the electrical system correctly, leading to starting problems or electrical fires. These are not minor inconveniences—they are safety hazards.

If you do not have experience with small engines, welding, and fuel system work, hire a mechanic who has done golf cart conversions before. Ask for references and photos of previous conversions. A good mechanic will charge more but will deliver a safe, reliable result.

Local regulations and where you can use a converted cart

Gas golf carts produce exhaust emissions and engine noise. Many municipalities restrict their use on public roads, in residential neighborhoods, or in parks. Some areas require emissions testing or noise certification before a gas cart can be registered for street use. Rules vary by city and county, so check with your local code enforcement office or planning department before converting.

If you plan to use the cart only on private property—your own land, a private golf course, or a private community—regulations are typically less strict. If you want to drive it on public roads or in regulated areas, you may face fines or confiscation if the cart does not meet local standards.

Electric carts, by contrast, produce zero emissions and minimal noise, making them legal in most places without special registration or testing. If local regulations are a concern, staying electric may be the simpler choice.

Frequently Asked Questions

Can I convert just the battery to a larger capacity instead of switching to gas?

Yes, and this is often a better option than a full gas conversion. Upgrading to lithium-ion batteries or adding more lead-acid batteries increases range and power without the cost and complexity of a gas engine. Lithium upgrades cost $2,000 to $4,000 but avoid the disposal hassle and keep your cart quiet and emission-free.

Will a converted gas cart have the same performance as a factory gas cart?

Not necessarily. A converted cart may have less power, rougher acceleration, or reliability issues if the engine is undersized or poorly installed. Factory gas carts are engineered as complete systems. A conversion is a retrofit, and retrofits often have compromises.

Can I convert back to electric if I change my mind?

Technically yes, but it is expensive and impractical. You would need to source a new motor, battery pack, and controller, and reinstall them. Most people who convert to gas and regret it straightforward buy a new electric cart rather than convert back.

What size engine should I use for my golf cart?

Most golf cart conversions use engines between 200 and 400 cubic centimeters. Smaller engines (200cc) are quieter and more fuel-efficient but slower. Larger engines (400cc) are faster but noisier and consume more fuel. Match the engine size to how you plan to use the cart and what local noise limits allow.

How often will I need to maintain a converted gas cart?

Gas engines require regular oil changes (every 50 to 100 hours of use), air filter replacements, spark plug maintenance, and carburetor cleaning. You will also need to winterize the fuel system if you store the cart for long periods. Maintenance is more frequent and complex than an electric cart, which needs only battery charging and occasional brake service.
