FAQ – Yamaha Serial Number Guide

Yamaha golf cars are classified by generations. Each generation had few changes during its lifetime, but each generation had many changes. The following are easily-identifiable markers from each generation:

  • The G1 entire body flips backward to access the engine/battery compartment. The gas version used a 2-cycle engine.
  • The G2/G9 has a lever inside the fuel/charge port to access the engine/battery compartment.
  • The G3/G5 Sunclassic cars have a tempered glass windshield similar to a street car. The G3 gas has a 2-cycle engine, while the G5 has a 4-cycle engine.
  • The G1, G2, G3, G5, G8, G9, G14, and G16 cars are 36 volt, while the G19, G22, and G29 cars are 48 volt.
