Vehicle Information
Yamaha GP338 Snowmobile (1973-1975)
The Yamaha GP338, produced from 1973 to 1975, was an iconic sport snowmobile, renowned for its performance and agility. Powered by a 338 cm³ two-stroke, two-cylinder engine, it made its mark with innovations and various configurations throughout its production. Initially launched in 1973 with single or twin carburetor options, the series underwent a major evolution in 1974 with the introduction of the GP338F model. This model not only increased horsepower to 44 hp but also incorporated a slide suspension system ("slide boggie"), replacing the earlier wheel boggie design. In 1975, the lineup expanded with the GPX338G and GS338, with the GPX model offering performance-oriented features such as fan cooling and Autolube oil injection, solidifying its reputation as a "muscle sled."
