Yamaha G16 Engine Swap: Compatible Golf Cart Engines
Like every mechanical wonder, the JN6 301cc 3-stroke engine originally used in the Yamaha G16 golf cart wears off after a certain period. Therefore, we consider that replacing the engine is preferable to wasting money on repairs that don’t fix the problem of an old engine.
Different models of engines are identical to the electrical system and power delivery suitable for swapping the JN6 engine of the G16. Some of these are the Lifan 15HP, Duramax 16HP, Briggs and Stratton Pro series, and Predator 13HP.
However, we couldn’t just remove the old engine and put on a new one because many secondary factors must be addressed while swapping. You might want to read this article till the end to get in-depth information on the compatible engines for a Yamaha G16.
Best-Suited Engines For Yamaha G16 Golf Cart
We analyzed different engine kits after conducting multiple online and retail marketplace research to find the engine that would work best for my Yamaha G16. Here are the six most compatible engines we filtered out for my G16.
Predator 13HP Golf Cart Engine
The Predator 13HP engine is a small 4-stroke engine suitable to adjust in the mounting area of a Yamaha G16. It has a displacement of 420cc, producing 13 horsepower at 3,600 rpm.
The fuel type used in this engine is common gasoline with a compression ratio of 8.5:1.
However, being a moderate-level engine, it uses an air cooling system which works fine for a day to day activity.
It’s worth mentioning that the Predator 13HP engine is not specifically designed for use in the G16.
Therefore, we might have to modify the lift height of the vehicle and the electrical system to install the new engine.
Installing a Predator 13HP engine in a golf cart may significantly increase its power and speed, which could affect its handling and safety.
Duramax 16HP Golf Cart Engine
we found the Duromax engine to be the most powerful in producing horsepower in this segment.
For engine swapping in G16, we must remove the fuel tank, the battery, the wiring, and the solenoids apart from removing the old engine. It is because none of that applies to the Duromax.
The Duromax is a 16 HP, 420cc 4-stroke air-cooled engine with a horizontal shaft and a single cylinder.
It’s got an electric start, which we must hook to the electrical system. The Comet 40 series clutch works better with this engine.
It fits the engine, but the issue is it didn’t fit the belt. After researching, we found that the 40 series clutch uses a narrower belt, and the original driven clutch uses a wider belt. Therefore, there needs to be a modification with the belt also.
However, once all fit in, the engine works perfectly with the Yamaha G16 and revives it to roll on the golf course for an extended period.
The best part of swapping the stock engine of the G16 with the Duromax is no need for modification in the chassis and lift of the vehicle.
Lifan 15 Hp Golf Cart Engine
Similar to other engines, the Lifan 15 Hp has a displacement of 420cc with 4-Stroke OHV Industrial Grade. It runs on gasoline with an electric start. Moreover, the 18 Amp external charging system.
We were amused to see the universal mounting pattern of this engine. Hence, we need not install any lift kit for my golf cart to support this engine.
Although, we might need to purchase a comet 780 torque converter with a compatible belt for an efficient outcome from the engine.
The wirings are not color-coded, which can be an issue for beginners like me. Hence, replacing the engine and proceeding with the installation under the expert’s supervision is advised.
Briggs and Stratton Vanguard V-Twin Engine
The Biggs and Stratton engines are renowned for producing small engine units. Its vanguard is a 420cc, 4-stroke single-cylinder engine suitable for the Yamaha G16.
However, judging by the dimension of this engine kit, the G16 seems lower to me and requires an additional lift kit.
Moreover, it comes with an electric start, and thus, we need to hook additional wirings for the ignition.
Its 16 amp default charging system is suitable to support the electrical systems of my Yamaha G16.
