Vehicle Information
Yamaha WaveRunner III 650 Personal Watercraft (1990-1996)
The Yamaha WaveRunner III 650, produced from 1990 to 1996, was a landmark personal watercraft, recognized as the world's first 3-seater PWC with reverse drive. This model primarily featured a robust 2-stroke, 633cc twin engine. From 1990 to 1995, the 633cc engine typically delivered 42 to 50 HP. A significant update occurred in 1996 when the WaveRunner III was upgraded to a more powerful 701cc engine, boosting output to 55 HP. Early 633cc models initially required fuel pre-mixing at a 50:1 ratio due to the absence of an oil injection system, a feature later introduced in subsequent model years. FAQ:
